750MHz Gain of 1 Triple
2:1Video Multiplexer
The LT6556 is a high speed triple 2:1 video multiplexer
with an internally xed gain of 1. The individual buffers
are optimized for performance with a 1k load and feature a
2VP-P –3dB bandwidth of 450MHz, making them ideal for
driving very high resolution video signals. Separate power
supply pins for each amplier boost channel separation
to 72dB, allowing the LT6556 to excel in many high speed
applications.
While the performance of the LT6556 is optimized for dual
supply operation, it can also be operated with a single sup-
ply as low as 4.5V. Using dual 5V supplies, each amplier
draws only 9.5mA. When disabled, the ampliers draw
less than 330A and the outputs become high impedance.
For applications requiring a xed gain of 2, refer to the
LT6555 datasheet.
The LT6556 is available in 24-lead SSOP and ultra-compact
24-lead QFN packages.
