IDT821068 - Integrated Device

IDT821068 OCTAL PROGRAMMABLE PCM CODEC

The IDT821068 is a feature rich, single-chip, programmable 8 channel PCM CODEC with on-chip filters. Besides the A-Law/ µ-Law companding and linear coding/decoding (16-bit 2’s complement), IDT821068 provides 2 programmable Tone generators per channel (which can also generate ring signals), 1 FSK generator, 1 programmable Teletax Signal generator and 2 progra.
