W6810 SINGLE CHANNEL VOICECODEC
1. GENERAL DESCRIPTION
The W6810 is a general-purpose single channel PCM CODEC with pin-selectable -Law or A-Law companding.
The device is compliant with the ITU G.712 specification. It operates off of a single +5V power supply and is
available in 20-pin SOG, SSOP, and TSSOP package options.. Functions performed include digitization and
reconstruction of voice signals, and band limiting and smoothing filters required for PCM systems. The filters are
compliant with ITU G.712 specification. W6810 performance is specified over the industrial temperature range of
–40C to +85C.
The W6810 includes an on-chip precision voltage reference and an additional power amplifier, capable of driving
300 loads differentially up to a level of 6.3V peak-to-peak. The analog section is fully differential, reducing noise
and improving the power supply rejection ratio. The data transfer protocol supports both long-frame and short-
frame synchronous communications for PCM applications, and IDL and GCI communications for ISDN
applications. W6810 accepts seven master clock rates between 256 kHz and 4.096 MHz, and an on-chip pre-
scaler automatically determines the division ratio for the required internal clock.
For fast evaluation and prototyping purposes, the W6810DK development kit is available.
