The GB4570 is a high performance video buffer/clamp used primarily for sync tip clamping of video signals. Key features include operation from ± 4.5 to ±13.2 V supply voltages, ±0.1 dB flatness to 80 MHz and availability of industry standard DIP and SOIC packages.
In a typical video application, the GB4570 clamps the sync tip to a known voltage. The clamping level can be set for normal sync tip clamping by connecting pin 3 to - 0.286 volts. For applications requiring non-standard sync tip clamping, the clamping voltage applied to pin 3 may be varied.
The GB4570 features a tight delay spread of only ± 0.15° at color burst frequencies and less than ± 1 millivolts clamping distortion.
