Product specification

RGB/YUV and fast blanking switch

TDA8601

FEATURES

• YUV/RGB and fast blanking switch

• 3-state output

• Selectable clamp:

– passive (with diodes) or

– active clamp

• Bandwidth greater than 22 MHz

• Fully ESD protected

• Latch-up free.

APPLICATIONS

• Standard and high definition television sets

• Peri-television sets.

GENERAL DESCRIPTION

The device is intended for switching between two RGB or

YUV video sources. The outputs can be set to a

high-impedance state to enable parallel connection of

several devices.

A HIGH level on SEL (pin 5) selects the video inputs of

Channel 2. The IOCNTR control pin (pin 16) defines the

3-state outputs and clamp inputs:

• HIGH = 3-state outputs (also for test; active clamp)

• LOW = passive clamp at the video inputs (diode)

• Sandcastle: the video signal is clamped with an active

clamp during the sync pulse.
