Description


The GB4551 is a high performance video buffer with DC restore primarily used for accurate back porch clamping. The circuit features of GB4551 a wideband differential amplifier that can be configured as a gain stage. The output signal voltage is limited to +2V above the clamp level in order to prevent damage to crosspoints or other circuits connected to the output.

The clamping action occurs when the STROBE (STB) input is taken to ground. GB4551 application would be for DC restoration during the back porch period. In this case the negative-going back porch pulse would be derived from an external sync separator circuit.

The GB4551 will operate from ± 9V to ±12V power supplies and will directly interface with Gennum's video crosspoint switches. The 8 pin SIP package is ideally suited for space restricted board layouts.
