UPD9611

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. FEATURES Single-chip CMOS monolithic LSI ITU-T Recommendation G.711/G.714 compliant Four-channel PCM CODECs integrated on a single chip Compatible with A-law and µ-law Digital gain setting for each channel Transmit : +7.5 to –8.0 dB (0.5 dB step) Receive : 0 to –15.5 dB (0.5 dB step) Data transfer system: Transmit/receive synchronization Data rate: 2048 kHz +5 V single power supply Power down function for each channel Low power consumption ORDERING INFORMATION Part Number Package 48-pin shrink SOP (375 mil) µPD9611GT The information in this document is subject to change without notice.
