QUAD NON-PROGRAMMABLE  
PCM CODEC  
821024  
DATASHEET  
DESCRIPTION  
FEATURES  
4 channel CODEC with on-chip digital lters  
Selectable A-law or μ-law companding  
Master clock frequency selection: 2.048 MHz, 4.096 MHz or  
8.192 MHz  
The IDT821024 is a single-chip, four channel PCM CODEC with on-  
chip lters. The device provides analog-to-digital and digital-to-analog  
conversions and supports both a-law and μ−law companding. The digital  
lters in IDT821024 provides the necessary transmit and receive ltering for  
voice telephone circuit to interface with time-division multiplexed systems.  
All of the digital lters are performed in digital signal processors operating  
from an internal clock, which is derived from MCLK. The xed lters set  
the transmit and receive gain and frequency response.  
- Internal timing automatically adjusted based on MCLK and frame  
sync signal  
Separate PCM and master clocks  
Single PCM port with up to 8.192 MHz data rate (128 time slots)  
Transhybrid balance impedance hardware adjustable via external  
components  
Transmit gains hardware adjustable via external components  
Low power +5.0 V CMOS technology  
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  
(FSRn and FSXn, 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 Ofce Switch, Digital Telephone and Integrated  
Voice/Data Access Unit.  
+5.0 V single power supply  
Package available: 32 pin PLCC, 44 pin TQFP
