DESCRIPTION
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.
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.
The GB4550A features a tight delay spread of only
±
0.15
degrees while the GB4550 maintains a
±
1.5 degree delay
spread. Both devices operate from
±
9 to
±
12 V power
supplies and will directly interface with Gennum's video
crosspoint switches.
The 8 pin SIP package is ideally suited for space restricted
board layouts.
APPLICATIONS
