IDT821054APFG - Brand New Integrated Circuit Systems Interface - CODECs
-
DESCRIPTION
The IDT821054A 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 IDT821054A also provides 2 programmable tone generators per channel (which can generate ring signals) and 2 programmable chopper clocks for SLICs.
