UPD9611 Datasheet Four-channel Pcm Codec

Manufacturer: NEC (now Renesas Electronics)

Overview: 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.

Key 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.
