DATA SHEET  
FEATURES  
DESCRIPTION  
adjustable clamp level from -5.5 V to +5.5 V at ±10 V  
The GB4550 and GB4550A are high performance mono-  
lithic 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.  
supplies.  
ultra low differential gain (0.02% typ.) and  
differential phase (0.03° typ.)  
wideband unity gain: GB4550 ±0.2 dB at 25 MHz  
GB4550A ±0.1 dB at 25 MHz  
both drive 150pF loads at full power, flat to 10 MHz.  
GB4550A — tight delay spread of ±0.15°at colorburst.  
convenient 8 pin SIP packaging.  
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.  
both can be configured as a gain stage with reduced  
The GB4550A features a tight delay spread of only ±0.ꢀ5  
degrees while the GB4550 maintains a ±.5 degree delay  
spread. Both devices operate from ±± to ±2 V power  
supplies and will directly interface with Gennum's video
