Single-Channel CODEC
The W681512 single channel voice CODEC is an
analog-to-digital and digital-to-analog converter
that complies with ITU-T G.712 specifications.
The CODEC features complete µ-Law and A-Law
companders (pin selectable) that are designed to
comply with ITU-T G.711 specifications. The chip
also offers a fully differential analog output.
In order to provide the cleanest possible signal,
the W681512 CODEC complies with the ITU-T
G.712 recommendation for analog-to-digital pre-
filters (also known as anti-aliasing filters) and
Digital-to-Analog post filter (signal smoothing
filter).
The W681512 CODEC contains an additional
analog power amplifier that drives higher current
output. The power amplifier gain levels can be
adjusted via a set of external resistors to drive an
output level of up to 6.3V, peak-to-peak, across a
300-Ω load.
The PCM interface for the W681512 produces 8-
bit digital data (µ-Law or A-Law) at a sampling
rate of 8kHz. It can communicate in four different
clock formats; short frame sync, long frame sync,
IDL and CGI. The W681512 is available in 20-pin
SOP and SSOP packaging.
For evaluation and prototyping purposes, a
development kit, the W681512DK, is available to
provide the system designer with a flexible
method for developing and testing an application
on a single, standalone platform.
