DESCRIPTION
The PCM3501 is a low cost, 16-bit CODEC designed
for modem Analog Front End (AFE) and speech pro-
cessing applications. The PCM3500’s low power op-
eration from +2.7V to +3.6V power supplies, along
with an integrated power-down mode, make it ideal for
portable applications.
The PCM3501 integrates all of the functions needed for
a modem or voice CODEC, including delta-sigma
digital-to-analog and analog-to-digital converters, in-
put anti-aliasing filter, digital high-pass filter for DC
blocking, and an output low-pass filter. The synchro-
nous serial interface provides for a simple, or glue-free
interface to popular DSP and RISC processors. The
serial interface also supports Time Division Multiplex-
ing (TDM), allowing up to four CODECs to share a
single 4-wire serial bus.
