• Manufacturer Part Number: LC8901Q
• Description: Digital Audio Interface Receiver
• Manufacturer: Sanyo

Microprocessor Interface Input
1. Input pin setting
2. Audio data output mode setting
The data input pins DIN1 to DIN4 have built-in amplifiers and can receive signals from a minimum amplitude of
400 mVp-p to a maximum amplitude of V
only for use with optical inputs. Amplifiers must be inserted before the inputs if these pins are to be used with
coaxial input.
The data input system multiplexer is controlled by input from the microprocessor interface. The tables show the
relationship between the microprocessor interface I5 to I13 codes and the data demodulation, DOUT1, and DOUT2
signals. Bits I0 to I4 and I15 are ignored.
There are two audio data output modes, one with a 16-bit MSB first format and one with a 20-bit LSB first format.
The I14 code determines the setting.
