FDigital control specifications

(1) Data format: total of 23 bits

(2) Timing (recommended conditions)

BH3854AS / BH3854AFS

(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)

(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 MIN.
