GB4571 Video Buffer with  
Precision Strobed DC Restore  
DATA SHEET  
FEATURES  
DESCRIPTION  
The GB4571 is a high performance video buffer with DC  
restore used primarily for accurate back porch clamping. Key  
features include operation from ±4.5 ꢀ to ±1±.3 ꢀ supply  
voltages, fast recovery from sudden changes in DC offset,  
±.1dBflatnesstoMHandavailabilityofindustrystandard  
DIP and SOIC packages.  
accurate clamping to within ± 1 mV  
less than 1 mV clamping distortion  
variable clamping range (VEE + 3.0 V to VCC - 4.5 V)  
ultra low differential gain and differential phase  
fast recovery from sudden changes in DC offsets  
less than ± 0.15° phase delay variation at 3.58 MHz  
± 0.1 dB flatness to 80 MHz  
In the typical back porch clamping application, a negative  
going back porch pulse from an external sync separator (such  
astheGS4ꢂꢂ1orGS4ꢂꢂ3)isappliedtotheGB4571'sSTROBE  
input. While STROBE is low, the GB4571 determines the  
correct DC level shift that should be applied to the input signal  
by integrating over the entire back porch period. This reduces  
sensitivity to noise and improves the accuracy of the DC  
restoration compared to systems using sample and hold  
techniques. Typical clamping accuracy of ±1 mꢀ is achieved  
by the GB4571.
