Advance Information MT9162 7-163 Overview The 5V single rail Codec features complete Analog/ Digital and Digital/Analog conversion of audio signals (Filter/Codec) and an analog interface to a standard analog transmitter and receiver (Analog Interface). The receiver amplifier is capable of driving a 20k ohm load. Functional Description Filter/Codec The Filter/Codec block implements conversion of the analog 0-3.3 kHz speech signals to/from the digital domain compatible with 64 kb/s PCM B-Channels. Selection of companding curves and digital code assignment are programmable. These are ITU-T G.711 A-law orµ-Law, with true-sign/Alternate Digit Inversion. The Filter/Codec block also implements a transmit audio path gain in the analog domain. Figure 3 depicts the nominal half-channel for the MT9162. The internal architecture is fully differential to provide the best possible noise rejection as well as to allow a wide dynamic range from a single 5 volt supply design. This fully differential architecture is continued into the analog interface section to provide full chip realization of these capabilities for the external functions. A reference voltage (V Ref), for the conversion requirements of the Codec section, and a bias voltage (V Bias), for biasing the internal analog sections, are both generated on-chip. VBias is also brought to an external pin so that it may be used for biasing external gain setting amplifiers. A 0.1µF capacitor must be connected from V Bias to analog ground at all times. Likewise, although VRef may only be used internally, a 0.1µF capacitor from the VRef pin to ground is required at all times. The analog ground reference point for these two capacitors must be physically the same point. To facilitate this the V Ref and VBias pins are situated on adjacent pins. The transmit filter is designed to meet ITU-T G.714 specifications. An anti-aliasing filter is included. This is a second order lowpass implementation with a corner frequency at 25 kHz. The receive filter is designed to meet ITU-T G.714 specifications. Filter response is peaked to compensate for the sinx/x attenuation caused by the 8 kHz sampling rate. Companding law selection for the Filter/Codec is provided by the A/ µ companding control pin. Table 1 illustrates these choices. Table 1: Law Selection Analog Interfaces Standard interfaces are provided by the MT9162. These are:

  • The analog inputs (transmitter), pins AIN+/AIN-. The maximum peak to peak input is 3.667Vpp µ− law and across AIN+/AIN- 3.8Vpp A-law.
  • The analog outputs (receiver), pins AOUT+/ AOUT -.This internally compensated fully differential output driver is capable of driving a load of 20k ohms. PCM Serial Interface A serial link is required to transport data between the MT9162 and an external digital transmission device. The MT9162 utilizes the strobed data interface found on many standard Codec devices. This interface is commonly referred to as Simple Serial Interface (SSI). The required mode of operation is selected via the CSL2-0 control pins. See Table 2 for selections based in CSL2-0 pin settings. Quiet Code The PCM serial port can be made to send quiet code to the decoder and receive filter path by setting the RxMute pin high. Likewise, the PCM serial port will send quiet code in the transmit path when the Code ITU-T (G.711) µ -Law A-Law + Full Scale 1000 0000 1010 1010 + Zero 1111 1111 1101 0101 -Zero (quiet code) 0111 1111 0101 0101 - Full Scale 0000 0000 0010 1010

MT9162 Advance Information 7-164 Table 2: Bit Clock Rate Selection TxMute pin is high. When either of these pins are low their respective paths function normally. The -Zero entry of Table 1 is used for the quiet code definition. SSI Mode The SSI BUS consists of input and output serial data streams named Din and Dout respectively, a Clock input signal (CLOCKin), and a framing strobe input (STB). A 4.096 MHz master clock is also required for SSI operation if the bit clock is less than 512 kHz. The timing requirements for SSI are shown in Figures 5 & 6. In SSI mode the MT9162 supports only B-Channel operation. Hence, in SSI mode transmit and receive B-Channel data are always in the channel defined by the STB input. The data strobe input STB determines the 8-bit timeslot used by the device for both transmit and receive data. This is an active high signal with an 8 kHz repetition rate. SSI operation is separated into two categories based upon the data rate of the available bit clock. If the bit clock is 512 kHz or greater then it is used directly by the internal MT9162 functions allowing synchronous operation. If the available bit clock is 128 kHz or 256 kHz, then a 4096 kHz master clock is required to derive clocks for the internal MT9162 functions. Applications where Bit Clock (BCL) is below 512 kHz are designated as asynchronous. The MT9162 will re-align its internal clocks to allow operation when the external master and bit clocks are asynchronous. Control pins CSL2, CSL1 and CSL0 are used to program the bit rates. CSL
