Single Channel
CODEC
The W6810 single channel CODEC is an analog-
to-digital and digital-to-analog converter that
complies with the specifications of the ITU-T G.712.
The CODEC includes a complete -Law and A-Law
companders (pin selectable) that are designed to
comply with the specifications of the ITU-T G.711.
In order to provide the cleanest signal possible, the
W6810 CODEC complies with the ITU-T G.712
recommendation for the Analog to Digital pre filters
(also known as anti-aliasing filters) and the Digital-
to-Analog post filter (signal smoothing filter).
The W6810 CODEC contains an additional analog
power amplifier to drive a higher current output. The
power amplifier gain levels can be adjusted by a set
of external resistors to drive an output level of up to
6.3V peak-to-peak across a 300-
The PCM interface of the W6810 produces 8-bit
digital data ( -Law or A-Law) at a sampling rate of
8kHz and can communicate in four different clock
formats, short frame sync, long frame sync, IDL
and CGI. The W6810 is available in four different 20-
pin packages; PDIP, SOG, SSOP and TSSOP.
For evaluation and prototyping purposes, a
development kit, the W6810DK, is available to
provide the system designer with a flexible method
for developing and testing an application on a
single, standalone platform.
