The GB4550 and GB4550A are high performance monolithic video buffer/clamps made on Gennum's LSI process. The feature of GB4550A 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 of GB4550A 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 of GB4550A is ideally suited for space restricted board layouts.
