DESCRIPTION
The IDT821024 is a single-chip, four channel PCM CODEC with on-
chip filters. The device provides analog-to-digital and digital-to-analog
conversions and supports both a-law and
μ
law companding. The digital
filters in IDT821024 provides the necessary transmit and receive filtering
for voice telephone circuit to interface with time-division multiplexed
systems. All of the digital filters are performed in digital signal processors
operating from an internal clock, which is derived from MCLK. The fixed
filters set the transmit and receive gain and frequency response.
In the IDT821024 the PCM data is transmitted to and received from
the PCM highway in time slots determined by the individual Frame Sync
signals (FSR
and FSX
, where n = 1-4) at rates from 256 KHz to 8.192
MHz. Both Long and Short Frame Sync modes are available in the
IDT821024.
The IDT821024 can be used in digital telecommunication applications
such as PBX, Central Office Switch, Digital Telephone and Integrated Voice/
Data Access Unit.
