Buffalo-III Integration Guide
by Leon van Bommel
Stereo (2-Channels)
  • PCM (I2S), or
  • DSD, or
  • S/PDIF (Consumer-level or TTL-level)

  • Outputs:
    Stereo (2 Channels)
  • Can be combined for mono

  • Power requirements:
    5.25VDC for powering onboard regulators.

  • Four-layer circuit board optimized for mixed signals
  • Based on the ESS Sabre32 Reference (ES9018) DAC chip
  • Pre-configured for 2-channel (stereo) operation
  • High-precision, ultra-low-phase noise clock and integrated reclocking
  • Optional external master clock connections
  • Three seperate series shunt regulator modules (Tridents) for Digital supplies
  • Dual series shunt voltage regulator module for AVCC supplies
  • Direct DSD, I2S and S/PDIF inputs supporting up to 32-bit/192kHz
  • Switchable stereo S/PDIF input, or 2 channels of PCM/DSD
  • Accepts both consumer-level and TTL-level S/PDIF input
  • 2-Channel (stereo) outputs can be used in current-output or voltage-output mode (depends on output stage used)
  • All connections by direct or optional terminal blocks (included)
  • Optional U.FL connections for digital inputs and external Master Clock
  • Built in digital volume control using the including volume pot
  • Onboard microcontroller and 16 configuration switches
