GB4570 Product details

DESCRIPTION

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, ±0.1dB 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.



FEATURES

•accurate sync tip clamping (±2 mV typical)

•less than 1 mV clamping distortion

•variable clamping voltage (VEE +3V to VCC -4.5 V)

•ultra low differential gain and differential phase

•less than ±0.15°phase delay variation at 3.58 MHz

•±0.1 dB flatness to 80 MHz

•±4.5 to ±13.2 V supply voltage range



APPLICATIONS

• Sync tip clamping of NTSC, PAL, SECAM and RGB Video Signals

• Input buffering and clamping

• Inter-system video signal clamping
