DESCRIPTION

The PCM4202 is a high-performance, stereo audio analog-to-digital (A/D) converter designed for professional and broadcast audio applications. The PCM4202 architecture utilizes a 1-bit delta-sigma modulator per channel, incorporating a novel density modulated dither scheme for improved dynamic performance. The PCM4202 supports 24-bit linear PCM output data, with sampling frequencies up to 216kHz. The PCM4202 can also be configured to output either 64x or 128x oversampled, 1-bit direct stream digital (DSD) data for each channel. Support for PCM and DSD output formats makes the PCM4202 suitable for a variety of digital audio recording and processing applications. The PCM4202 includes a flexible audio serial port inter- face, which supports standard audio data formats. Audio data format selection, sampling mode configuration, and high-pass filter functions are all programmed using dedi- cated control pins. The PCM4202 operates from a +5V analog power supply and a +3.3V digital power supply. The digital I/O pins are compatible with +3.3V logic families. The PCM4202 is available in a small SSOP-28 package. I2S is a registered trademark of Royal Philips Electronics B.V., The Netherlands.

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.

These differences are noted here for clarity. /C0068The full-scale input of the PCM4202 is 6.0VPP differential, while it is 5.0VPP for the PCM1804. This is a result of the PCM4202 having an internal +3.0V voltage reference, and the PCM1804 having an internal +2.5V voltage reference. /C0068The PCM1804 includes +5V tolerant digital inputs. The PCM4202 does not include these because the digital inputs are designed for interfacing to +3.3V logic. /C0068The reset pin (RST) pin of the PCM4202 has an internal pull-up resistor. For the PCM1804, this pin has an internal pull-down resistor. /C0068When operating in Master mode with Single Rate sampling selected, the audio serial port bit clock (BCK) is equal to 64f S for the PCM1804, while the BCK rate is equal to 128fS for the PCM4202. /C0068The following pins on the PCM4202 and PCM1804 have different names, but they perform the same functions.
