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
