UPD9611 Datasheet, PDF (1/28 Pages) NEC – FOUR-CHANNEL PCM CODEC

PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
µPD9611
FOUR-CHANNEL PCM CODEC
The µPD9611 incorporates 4-channel A-law/µ-law PCM CODECs compliant with ITU-T Recommendation G.711/
G.714 and is suitable for applications such as PBX analog subscriber line circuits.
Its gain setting circuit allows transmit/receive gain to be set for 4 channels independently by externally inputting
digital signals.
