QUAD PCM CODEC WITH  
PROGRAMMABLE GAIN  
IDT821034  
DESCRIPTION:  
FEATURES:  
· 4 channelCODEC withon-chipdigitalfilters  
· Software Selectable A-law/m-lawcompanding  
· Programmablegainsetting  
The IDT821034 is a single-chip, four channel PCM CODEC with on-  
chip filters and programmable gain setting. This device provides both  
m-Law and A-Law companding digital-to-analog and analog-to-digital  
conversions based on ITU-T G.711 - G.714 specifications. The digital  
filters in IDT821034 provides the necessary transmit and receive filtering  
for voice telephone circuit to interface with time-division multiplexed  
systems. The IDT821034 has a flexible PCM interface with software  
selectable timing modes and independently programmable time slot for  
each transmit and receive channel. It also integrates the SLIC signaling  
functions through internal registers. The CODEC and SLIC control/status  
registers are accessed via the Serial Control Interface.  
· Automatic master clock frequency selection: 2.048MHz, 4.096  
MHz or 8.192MHz  
· Flexible PCM interface with up to 128 programmable time slots,  
data rate from 512 kbits/s to 8.192 Mbits/s  
· 5 SLIC signaling pins per channel  
· FlexibleSerialControlInterfacetomicrocontroller  
· Software programmable timing modes  
· TTLandCMOScompatibledigitalI/O  
· MeetsorexceedsITU-TG.711-G.714requirements  
· +5Vsinglepowersupply  
The IDT821034 can be used in digital telecommunication applications  
such as PBX, Central Office Switch, Digital Telephone and Integrated Voice/  
Data Access Unit.  
· Low power consumption: 100mW Typ.  
· Operating temperature range: -40 °C to +85 °C  
· Packages available: 52 pin PQFP
