DESCRIPTION
The PCM175x is a CMOS, monolithic, integrated
circuit, which includes stereo digital-to-analog
converters and support circuitry in a small 16-lead
SSOP package. The data converters use TI's
enhanced multilevel delta-sigma architecture, which
employs 4th-order noise shaping and 8-level
amplitude quantization to achieve excellent dynamic
performance and improved tolerance to clock jitter.
The PCM175x accepts industry standard audio data
formats with 16- to 24-bit data, providing easy
interfacing to audio DSP and decoder chips.
Sampling rates up to 200 kHz are supported. 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.
