Introduction

AI Translation

The W681310 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 from a single +3V 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. W681310 performance is specified over the industrial temperature range of -40°C to +85°C. The W681310 includes an on-chip precision voltage reference and an additional power amplifier, capable of driving 300Ω loads differentially up to a level of 3.544V 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. W681310 accepts eight master clock rates between 256 kHz and 4.800 MHz, and an on-chip pre-scaler automatically determines the division ratio for the required internal clock. For fast evaluation and prototyping purposes, the W681310DK development kit is available.
