BCLK

Luminance output pin for the S pin.
The output amplitude (output current
for 1 LSB) of the DAC is specified
using an external resistor, and this pin
controls the value of the current flow-
ing per bit.
When there is HIGH input at the signal
input pin, which switches to and from
the low power consumption mode, this
turns off the output from the YOUT
and COUT pins.
Output for the internal clock.
When CLKSW is HIGH, the VCLK buff-
er output.
When CLKSW is LOW, the VCLK 1 / 2
cycle output.
