GB4550 & GB4550A

Monolithic Video Buffer/Clamp

DATA SHEET

FEATURES

DESCRIPTION

• adjustable clamp level from -5.5 V to +5.5 V at ±10 V

The GB4550 and GB4550A are high performance mono-

lithic video buffer/clamps made on Gennum's LSI process.

They feature a wideband differential amplifier that can be

configured as a gain stage. The output signal voltage is

limited to +2V above the clamp level in order to prevent

damage to crosspoints connected to the output.

supplies.

• ultra low differential gain (0.02% typ.) and

differential phase (0.03° typ.)

• wideband unity gain: GB4550 ±0.2 dB at 25 MHz

GB4550A ±0.1 dB at 25 MHz

• both drive 150pF loads at full power, flat to 10 MHz.

• GB4550A — tight delay spread of ±0.15°at colorburst.

• convenient 8 pin SIP packaging.

The clamping level can be set for normal sync tip clamping

by connecting pin 4 to -0.286 volts. For other applications,

the clamping voltage level can be varied from -5.5 to +5.5

volts.

• both can be configured as a gain stage with reduced

The GB4550A features a tight delay spread of only ±0.ꢀ5

degrees while the GB4550 maintains a ±ꢀ.5 degree delay

spread. Both devices operate from ±± to ±ꢀ2 V power

supplies and will directly interface with Gennum's video

crosspoint switches.

• Pb-free and Green

PIN CONNECTIONS

The 8 pin SIP package is ideally suited for space restricted

board layouts.
