FEATURES
• wideband, unity gain, stable operation
(± 0.1 dB at 100 MHz when CL = 27 pF)
(full power BW = 120 MHz when CL = 47 pF).
• selectable high and low current operating
modes (IL = 10 mA or IL = 20 mA)
• drives high capacitance loads (CL = 180 pF)
to 70 MHz at -3 dB.
• extremely low differential phase and gain
• convenient 8 pin DIP / SOIC packaging
• 100 µW disabled power consumption

DATA SHEET
DESCRIPTION
The GB4600 is a high performance, monolithic unity gain
video buffer made on Gennum's proprietary LSI process.
The device features a stable wideband topology capable
of driving high capacitance video busses.
Optimal system power/bandwidth can be achieved by
using the high/low current mode select (I-SET). In addition,
the GB4600 can be disabled by taking the ENABLE pin to
ground. The ENABLE input is TTL and 5 V CMOS compatible.
The GB4600 operates from ±4.5 to ±5.5 V power supplies
and typically draws 30 mA of current when I-SET is not
connected. The supply current drops by approximately
50% when I-SET is directly connected to VEE.
A typical application for the GB4600 is interfacing Gennum's
wide range of video crosspoint switches. The 8 pin PDIP
and 8 pin SOIC packaging is ideally suited for space
restricted board layouts.
APPLICATIONS
• Input and output buffering in wide crosspoint matrices
• Inter-board video signal buffering
• Inter-system video signal buffering
