IDT82V1068

The IDT82V1068 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 2ís complement), the IDT82V1068 provides 2 programmable tone generators per channel (which can also generate ring signals), 4 FSK generators shared by 8 channels and 2 programmable chopper clocks for the SLIC.
