M65863FP

This Audio Decoder for Dolby Digital (AC-3)^*1 M65863FP is a single device. The device decodes AC-3 bitstreams into PCM audio. Dolby Digital (AC-3) is a multi-channel audio coding algorithm developed by Dolby Laboratories, Inc.
• Decoding
  1) 5.1 ch AC-3 bitstream
  2) Dolby Pro Logic^*1 encoded 2ch Dolby Digital (AC-3) bitstream
  3) Dolby Pro Logic encoded 2ch PCM data
• All input combinations from 1 to 5.1 channels
• Output : mono 5.1 surround
• Sampling rates : 32kHz, 44.1 kHz, 48 kHz and 96 kHz (96 kHz is for linear PCM only)
• Supports a maximum bit rate of 640 kbps at a full service (up to 448 kbps when 32 kHz sampling rates)
• 2 DIR (Digital Audio Interface Receiver)/ADC input interfaces
• Serial input bitstream interface for DEMUX
• PCM output interface
   Standard 3-wire DAC output interface (data,clock,LR clock), 16/18/20/24 bit DAC word size
• Supports IEC958 digital audio output for Dolby Digital (AC-3) data stream
• I²C^*2 interface and clocked serial (4 line) interface for host microcontroller
• Generates audio test noise
• 2nd DSP I/F (twice higher PCM transfer rate)
• Controllable dynamic range compression
• Programmable center and surround channel delays
• Dialogue level control
• No external memory required (M65863FP doos not have memory space for surround delay)
