Product Description

DESCRIPTION
The IDT821054 is a feature rich, single-chip, programmable 4-channel PCM CODEC with on-chip filters. Besides the µ-Law/A-Law companding and linear coding/decoding (14 effective bits + 2 extra sign bits), the IDT821054 also provides 1 FSK generator for sending Caller-ID messages, 2 programmable tone generators per channel (which can generate ring signals) and 2 programmable chopper clocks for SLICs.
FEATURES
