• Manufacturer Part Number: ADV3203
• Manufacturer: AD [Analog Devices]

The internal connection of the ADV3202/ADV3203 is
controlled by a TTL-compatible logic interface. Serial loading
into a first rank of latches preprograms each output. A global
update signal moves the programming data into the second
rank of latches, simultaneously updating all outputs. A serial
out pin allows devices to be daisy chained together for single
pin programming of multiple ICs. A power-on reset pin is
available to prevent bus conflicts by disabling all outputs.

The ADV3202 can operate on a single +5 V supply, powering
both the signal path (with the VPOS/VNEG supply pins) and
the control logic interface (with the VDD/DGND supply pins).
However, to easily interface to ground referenced video signals,
split supply operation is possible with ±2.5 V. (The ADV3203 is
intended to operate on ±3.3 V.) In the case of split supplies, a
flexible logic interface allows the control logic supplies
(VDD/DGND) to be run off +3.3 V/0 V to +5 V/0 V while the
core remains on split supplies.
