3 Description
The PCM175x devices are stereo digital-to-analog
converters (DACs) based on TI's enhanced delta-
sigma architecture which employ 4th-order noise
shaping and 8-level amplitude quantization to achieve
excellent dynamic performance and improved clock
jitter tolerance. The PCM175x devices easily interface
with audio DSP and decoder chips because of the
devices' support of industry-standard audio data
formats with 16- and 24-bit data. The PCM175x
devices can be controlled in a hardware mode, or a
full set of user-programmable functions is accessible
through a three-wire serial control port, which
supports register-write functions.
The PCM1753 is pin-compatible with the PCM1748,
PCM1742, and PCM1741, except for pin 5.
