DC-restore clamp reference input. In an AC-coupled configuration
(DC-Restore clamp enabled), the sync tip of composite video inputs
will be restored to this level. Set to 0.3V to 0.7V for optimum
performance.
In an DC-coupled configuration (DC-Restore clamp disabled), this pin
should be tied to ground.
Do not let the VREF pin float! A floating VREF pin drifts high and, if
the clamp function is enabled, will cause all of the outputs to
simultaneously try to drive ~4V DC into their 150Ω loads.
Serial Latch. Serial data is latched into ISL59530 on rising edge of
SLATCH.
