750MHz Gain of 1 Triple

2:1Video Multiplexer

DESCRIPTIO

FEATURES

■

750MHz –3dB Small Signal Bandwidth

The LT 6556 is a high speed triple 2:1 video multiplexer

■

450MHz –3dB 2V Large-Signal Bandwidth

with an internally ﬁxed gain of 1. The individual buffers

are optimized for performance with a 1k load and feature a

P-P

■

120MHz 0ꢀ1dB Bandwidth

High Slew Rate: 2100V/µs

2V –3dB bandwidth of 450MHz, making them ideal for

P-P

Fixed Gain of 1; No External Resistors Required

72dB Channel Separation at 10MHz

52dB Channel Separation at 100MHz

drivingveryhighresolutionvideosignals. Separatepower

supply pins for each ampliﬁer boost channel separation

to 72dB, allowing the LT6556 to excel in many high speed

applications.

–87dBc 3rd Harmonic Distortion at 10MHz, 2V

Low Supply Current: 9.5mA per Ampliﬁer

6.5ns 0.1% Settling Time for 2V Step

While the performance of the LT6556 is optimized for dual

supplyoperation, itcanalsobeoperatedwithasinglesup-

ply as low as 4.5V. Using dual 5V supplies, each ampliﬁer

draws only 9.5mA. When disabled, the ampliﬁers draw

less than 330µA and the outputs become high impedance.

For applications requiring a ﬁxed gain of 2, refer to the

LT6555 datasheet.

≤ 330µA per Ampliﬁer When Disabled

Differential Gain of 0.033%, Differential Phase of 0.022°

Wide Supply Range: 2.25V ꢀ4.5Vꢁ to 6V ꢀ12Vꢁ
