DESCRIPTION
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.
Serial data clock
Serial data input
Serial data output. Can be tied to SDI of another ISL59530 to enable
daisy-chaining of multiple devices.
Reset input. Pull high then low to reset device, but not needed in
normal operation. Tie to ground in final application.
Power supply for SDO pin. Tie to +5V for a 0V to 5V SDO output
signal swing.
