1. GENERAL DESCRIPTION
The
W681512
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 +5V
power supply and is available in 20-pin SOG (SOP), SSOP and TSSOP package. 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.
W681512
performance is specified over the industrial temperature range of –40
°
C to +85
°
C.
The
W681512
includes an on-chip precision voltage reference and an additional power amplifier,
capable of driving 300
Ω
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.
W681512
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.
