FDigital control specifications
(1)
(2)
(1) Surround is ON when the bit data is 0, and OFF when
the bit data is 1.
(2) Pins 1 through 4 are set so that the output transistors
will turn OFF if data is not input when the power is turned
ON. They turn ON when the bit data is 1, and OFF when
the bit data is 0.
(3) “H” level is 4V or greater. “L” level is 1V or less.
(4) Make the end of each control command LOW.
FVolume data settings (reference values)
640
Audio ICs
Data format: total of 23 bits
Timing (recommended conditions)
(5) The MUTE function can be controlled externally if the
VC (volume control) pin is configured as shown in the dia-
gram above. Attenuation is equal to the figure for attenu-
ation when volume is at M
