TDA8601

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.

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.
