1. GENERAL DESCRIPTION
The
dedicated to the USB accessory market by supporting a derivative 2MHz clock. The device is
compliant with the ITU G.712 specification. It operates from a single +5V power supply and is
available in 20-pin SOP package option. 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.
temperature range of –40°C to +85°C.
The
capable of driving 300Ω 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.
master clock rate, and an on-chip pre-scaler automatically determines the division ratio for the
required internal clock.
