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
