The GB4550 and GB4550A are high performance monolithic video buffer/clamps made on Gennum's LSI process. They feature 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 connected to the output.
The clamping level can be set for normal sync tip clamping by connecting pin 4 to -0.286 volts. For other applications, the clamping voltage level can be varied from -5.5 to +5.5 volts.
The GB4550A features a tight delay spread of only ±0.15 degrees while the GB4550 maintains a ± 1.5 degree delay
spread. Both devices operate from ± 9 to ±12 V 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.
