DESCRIPTION

The PCM4104 is a high-performance, four-channel digital-to-analog (D/A) converter designed for use in professional audio applications. The PCM4104 supports 16- to 24-bit linear PCM input data, with sampling frequencies up to 216kHz. The PCM4104 features lower power consumption than most comparable stereo audio D/A converters, making it ideal for use in high channel count applications by lowering the overall power budget required for the D/A conversion sub-system. The PCM4104 features delta-sigma architecture, employing a high-performance multi-level modulator combined with a switched capacitor output filter. This architecture yields lower out-of-band noise and a high tolerance to system clock phase jitter. Differential voltage outputs are provided for each channel and are well-suited to high-performance audio applications. The differential outputs are easily converted to a single-ended output using an external op amp IC. The PCM4104 includes a flexible audio serial port interface, which supports standard and time division multiplexed (TDM) formats. Support for TDM formats simplifies interfacing to DSP serial ports, while supporting a cascade connection for two PCM4104 devices. In addition, the PCM4104 offers two configuration modes: Standalone and Software-Controlled. The Standalone mode provides dedicated control pins for configuring a subset of the available PCM4104 functions, while Software mode utilizes a serial peripheral interface (SPI) port for accessing the complete feature set via internal control registers. The PCM4104 operates from a +5V analog power supply and a +3.3V digital power supply. The digital I/O is compatible with +3.3V logic families. The PCM4104 is available in a TQFP-48 package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Input data word length is 24 bits with triangular PDF dither added for dynamic range and THD+N tests. Idle channel SNR is measured with both the soft and zero data mute functions disabled and 0% full-scale input data with no dither applied. The measurement bandwidth is limited by using the Audio Precision 10Hz high-pass filter in combination with either the AES17 20kHz low-pass filter or AES17 40kHz low-pass filter. All A-weighted measurements are performed using the Audio Precision A-weighting filter in combination with either the 22kHz or 80kHz low-pass filter. Measurement mode is set to RMS for all parameters. The AVERAGE measurement mode will yield better typical performance numbers. (2)Idle Channel SNR is not limited by word length.

Software mode operation provides full access to the features of the PCM4104 by allowing the writing and reading of on-chip control registers. This is accomplished using the four-wire SPI port. The following paragraphs provide a brief description of each function available when using Software mode. Digital Attenuation The audio signal for each channel can be attenuated in the digital domain using this function. Attenuation settings from 0dB (unity gain) to −119.5dB are provided in 0.5dB steps. In addition, the attenuation level may be set to the mute state. The rate of change for the digital attenuation function is one 0.5dB step for every eight LRCK periods. Each channel has its own independent attenuation control, accessed using control registers 1 through 4. The reset default setting for all channels is 0dB, or unity gain (no attenuation applied). Digital De-Emphasis The de-emphasis function is accessed through Control Register 5 using the DEM[1:0] bits. The reset default setting is that the de-emphasis is disabled for all four channels. De-emphasis filter operation is described in the Standalone Mode Configuration section of this data sheet. Soft Mute Each of the four D/A converter channels has its own independent soft mute control, located in Control Register The reset default is normal output for all four channels with the soft mute function disabled. The MUTE input (pin 10) also functions in Software mode, with a high input forcing soft mute on all four channels. Zero Data Mute The PCM4104 includes a zero data detection and mute function in Software mode. This function automatically mutes a given channel when 1024 consecutive LRCK periods of all zero data are detected for that channel. The zero data mute function is enabled and disabled using the ZDM bit in Control Register 5. The zero data mute function is disabled by default on power up or reset. Output Phase Reversal The PCM4104 includes an output phase reversal function, which provides the ability to invert the output phase for all four channels, either for testing or for matching various output circuit configurations. This function is controlled using the PHASE bit, located within Control Register 5. The output phase is set to noninverted by default on power up or reset. Sampling Mode Sampling mode configuration was discussed earlier in this data sheet, with Table 1 providing a reference for common sampling and system clock frequencies. The FS0 and FS1 bits located in Control Register 6 are used to set the sampling mode. The sampling mode defaults to Single Rate on power up or reset. Power-Down Modes The power-down control bits are located in Control Register 6. These bits are used to power down pairs of D/A converters within the PCM4104. The PDN12 bit is used to power down channels 1 and 2, while the PDN34 bit is used to power down channels 3 and 4. When a channel pair is powered down, it ignores the audio data inputs and sets its outputs to a high-impedance state. By default, the power-down bits are disabled on power up or reset. Software Reset This reset function allows a reset sequence to be initiated under software control. All control registers are reset to their default state. The reset bit, RST, is located in Control Register 6. Setting this bit to 1 initiates a one-time reset sequence. The RST bit is cleared by the initialization sequence. Audio Data Formats, LRCK Polarity, and BCK Sampling Edge Control Register 7 is used to configure the PCM4104 audio serial port. Audio serial port operation was discussed previously in this data sheet; refer to that section for more details regarding the functions controlled by this register. The control register definitions provide additional information regarding the register functions and their default settings.
