1. GENERAL DESCRIPTION
The W6810 is a general-purpose single channel PCM CODEC with pin-selectable
μ
-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 PDIP, 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 –40
°
C to +85
°
C.
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.
