AVAILABLE PACKAGING
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 V to ± 13.2 V supply
voltages, fast recovery from sudden changes in DC offset,
± 0.1 dB flatness to 80 MHz and availability of industry standard
DIP and SOIC packages.
In the typical back porch clamping application, a negative
going back porch pulse from an external sync separator (such
as the GS4881 or GS4882) is applied to the GB4571's STROBE
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 mV is achieved
by the GB4571.
