PRELIMINARY DATA SHEET MAD 4868A Micronas May 11, 2004; 6251-636-1PD 3 Micronas Audio Delay 1. Introduction The Micronas Audio Delay IC MAD 4868A acts as a delay line for TV audio and consumer audio applica- tions. The IC is designed for synchronizing audio and video signals ensuring “Lip Sync” by delaying the audio signal with the same amount of time as the video signal is delayed in a TV’s video processing. For TV designs, independent signals for loudspeakers, headphones, and line-out or S/PDIF out must be pro- vided, resulting in the need to delay six independent audio channels. Especially modern flat panel TVs (LCD- or plasma- TVs) require “Lip Sync” because of their video deinter- lacing, processing, scaling, and pixel-oriented display. In battery-operated “wireless TVs” using digital trans- mission, the compression/ decompression also may delay video more than audio. Therefore, additional audio delay is necessary. Consumer audio applications such as A/V-Receivers or HTiB can also use MAD 4868A to offer “Lip Sync” as an additional feature to delay audio according to the video delay appearing in the TV, beamer, or monitor used in a home cinema setup. The MAD 4868A is equipped with all interfaces, as well as embedded RAM. This makes the IC easy to use and avoids RAM availability and pricing problems. In its PMQFP44-1 package with 0.8 mm pitch, the MAD 4868A requires only little PCB space but is suit- able for wave soldering and reflow soldering. 1.1. Features – 32 k audio samples RAM: Total delay time of 680 ms at 48 kHz or 1020 ms at 32 kHz sampling rate – 32/18-bit word width: 32-bit High-Resolution mode or 18-bit Standard mode – Sampling rates from 32 kHz to 48 kHz for serial 8-channel mode are supported – Sampling rates from 4 kHz to 192 kHz for parallel 2-channel mode are supported – Memory allocation: MAD 4868A’s memory can be allocated for 1…8 audio channels. Delay time can be programmed for each channel individually. 1.2. Interfaces – 8-channel Micronas I 2S input and output: In combination with Micronas ICs (serial mode) (e.g. MSP 44/46xyK, MAS 35xyH), eight audio channels can be routed through MAD 4868A by using four lines only. –4 ×2-channel standard I2S inputs and outputs (paral- lel mode) allow routing eight audio channels with sampling rates of 4…192 kHz through MAD 4868A 2C control for delay time programming – Address select to set one out of two available I 2C addresses 1.3. Miscellaneous – No crystal required: The MAD 4868A derives all internal clocks from the I2S clock. – Very few external components required – 5 V or 3.3 V single supply voltage – Very low power consumption – 5 kHz to 192 kHz sampling rates – Cascadable, extendable: Two MAD 4868As can be cascaded to extend the delay time, either in 8-channel (serial) mode using one data line or in 2-channel (parallel) mode using up to four data lines.

Between 1 and 8 channels can be delayed indi- vidually by a programmable number of samples n The delay RAM offers, depending on the accumulated adjusted delay, a word width of 32 or 18 bits. The accumulated delay must not exceed 7FF0 hex (32752dec) samples (i.e. 682 ms @ 48 kHz F s). As the bit clock (I2S_DEL_CL) is limited to 12.288 MHz and the used I2S bus format has a fixed word length of 32 bit, the maximum sample rate f s is 192 kHz in parallel mode (2-channels per data line) and 48 kHz in serial mode (8-channels on I2S_DEL_IN1/OUT1). 2.2. I2S Bus Interface The MAD 4868A has four I2S data input lines and four I2S data output lines which together with I2S_DEL_WS and I2S_DEL_CL form one I 2S bus interface for vari- ous sample rates in serial (8-channel) or parallel (2- channel) mode. The I2S_DEL_CL, I2S_DEL_WS, and I2S_DEL_IN1...4 are inputs to the MAD 4868A (tristate) while I2S_DEL_OUT1...4 are outputs. Bit[1:0] of the CONTROL register set the output driver active or tristate and its strength to weak or strong (see Table 3–3 on page 10). The interface works only in synchronous slave mode and with a fixed wordlength of each audio sample of 32 bits. Two different opera- tional modes can be adjusted as described in the fol- lowing sections.

2.2.1. Serial Mode - One Data Line The MAD 4868A is capable of receiving signals with up to eight audio samples in a fixed 8-channel I 2S for- mat on one data line (serial mode). The interface con- sists of the pins: – I2S_DEL_IN1: I 2S data input, with 8 audio channels per I2S_DEL_WS cycle and 32 bit per audio sample – I2S_DEL_OUT1: I2S data output, with 8 audio channels per I2S_DEL_WS cycle and 32 bit per audio sample – I2S_DEL_CL: I2S clock – I2S_DEL_WS: I2S word strobe signal defines the frame start at the sample rate. As the bit clock must not exceed 12.288 MHz, the maximum sample rate is limited to 48 kHz when the MAD 4868A is operated in this mode. This mode is used for the connection to the Delay Line Interface of the MSP 44/46xyK. In serial mode, the number of audio channels must be even and less or equal eight. A timing diagram is shown in Fig. 4–8 on page 21. In this mode, it is possible to mute each output channel individually by means of the CONTROL register bit[2:9.] Note: DVSUP2 drives the pins DA_IN_2...4 and DA_OUT_2...4. To avoid radiation from not con- nected pins, it is recommended not to connect DVSUP2 when MAD 4868A is to be used in Serial Mode. 2.2.2. Parallel Mode - Four Data Lines The MAD 4868A is capable of receiving stereo signals on up to four I2S data lines in Parallel Mode with a total of up to eight audio channels. The interface consists of the pins: – I2S_DEL_IN1, I2S_DEL_IN2, I2S_DEL_IN3, I2S_DEL_IN4: I 2S data input with 2 audio channels per I2S_DEL_WS cycle and 32 bit per audio sample – I2S_DEL_OUT1, I2S_DEL_OUT2, I2S_DEL_OUT3, I2S_DEL_OUT4: I 2S data output with 2 audio channels per I2S_DEL_WS cycle and 32 bit per audio sample – I2S_DEL_CL: I2S clock – I2S_DEL_WS: I2S word strobe signal defines the left and right sample at the sample rate. As the bit clock must not exceed 12.288 MHz, the sample rate can be a maximum of 192 kHz when MAD 4868A is operated in this mode. This mode is used for connection to e.g. the I 2S interface of the Mic- ronas MSP 34/44xyG or any other audio DSP .
PRELIMINARY DATA SHEET MAD 4868A Micronas May 11, 2004; 6251-636-1PD 7 2.3. Delay Line The MAD 4868A has a delay line of 32k Words of RAM built in. The RAM can be split up into portions of differ- ent length to delay between 1 and 8 channels of audio. This makes the MAD 4868A very flexible. All channels can be delayed individually. The maximum amount of adjusted delay must not exceed 7FF0 hex (32752 dec) samples. Equipped with a pointer unit and programmed with variable pointer offsets for the delay channels 1 to 8, the programming of the individual delay times is real- ized by means of its own control register for each delay channel (see Table 3–3 on page 10). The delay time depends on the used sample fre- quency on the I 2S-bus. Since, not the delay time, but the number of delayed samples is programmed, the corresponding number of samples is calculated using the follwing formula: In the pointer unit, the offsets are used as increments for the address pointer to receive the correct RAM address of the delayed sound samples. Note: Reprogramming the delay length of a channel affects the output of the channels with higher numbers. Due to the “linked list” principle of the RAM organisation, the upper channels read from “wrong memory” until it is filled up with new audio samples. Therefore, it is recommended to mute the output of the delay line for the max programmed delay time of all channels. 2.4. Word Width The audio sample word width inside the RAM of the MAD 4868A depends on the adjusted number of sam- ples for the delay. MAD 4868A automatically switches the word width to 32 bit if the total delay length is below 3FF8hex (16376 dec) i.e. half of the maximum length. Otherwise, the delay line is 18 bit wide. By means of bit[14] of the CONTROL register, a read out value is available in parallel mode which indicates the internally adjusted word width. 2.5. Output Data Mute The output data channel 1-8 can be muted by means of the CONTROL register bit[2:9]. In serial mode, each output data channel can be muted individually, while in parallel mode, all channels 1-8 have to be adjusted individually to the same value. It is recommended to mute the output data channels during the power-up sequence of the MAD 4868A, as well as during re- adjustment of the delay time during normal operation. To avoid any audible disturbances, the minimum mute time must be at least the maximum programmed delay time of all channels. 2.6. Reset The Reset is active low and resets the I 2S and I 2C- interfaces of the MAD 4868A. Since there is no RAM clear facility, the output of the MAD 4868A after reset is random, as long as no valid samples have been inserted and passed the delay line (e.g. after Reset, enable the I 2S bus output but keep Mute active until the maximum programmed delay time is passed). 2.7. RAM Clear A RAM Clear can be performed manually. It is recom- mended to apply a manual RAM Clear after the power- up of the MAD 4868A. Mute the output data channel 1- 8, apply a digital zero signal on all used channels. This can be achieved, for example, by selecting an I input with a prescaler setting to Mute in the MSP 44/ 46xyK for all used MAD 4868A input channels. The digital zero signal must be applied for at least the max- imum programmed delay time of all channels. nx = number of samples tms = time in milliseconds fs = sample rate nx tms x() fs×() 1 –=

- Control Interface 3.1. I2C Bus Interface The MAD 4868A is controlled via its I 2C bus slave interface. The IC is selected by transmitting an MAD 4868A device address. In order to allow two MAD 4868A ICs to be connected to a single bus, an address select pin (ADR_SEL) has been implemented. With ADR_SEL pulled to high or low, the MAD 4868A responds to dif- ferent device addresses. A device address pair is defined as a write address and a read address. Writing is done by sending the write device address, followed by the subaddress byte and the data bytes. Reading is done by sending the write device address, followed by the subaddress byte. Without sending a stop condition, reading of the addressed data is com- pleted by sending the device read address and read- ing two bytes of data. See Table 3–1 for a list of available device addresses. See Table 3–2 for a list of available subaddresses. A general timing diagram of the I 2C bus is shown in Fig. 3–1 on page 9.
