ISL59837

200MHz Single Supply Video Driver With Charge Pump and Power Down

DATASHEET

The ISL59837 is a revolutionary device that allows true single-

supply operation of video amplifiers. Designed for systems

requiring output swing below ground but lacking a negative

power supply, the ISL59837 generates the required negative

rail internally from a +3.3V power supply. This allows for

DC-accurate coupling of video onto a 75

 double-terminated

line. The buffers have an integrated 6dB, eliminating the need

for external gain-setting resistors. An external reference

voltage can be applied to the REF pin to shift the analog video

level down by the desired amount. The charge pump and

amplifiers can be placed in a power down mode, consuming

less than 1mA of current.

Features

• Triple single-supply buffer

• Generates negative rail from from single +3.3V supply

• No output DC blocking capacitor needed

• 200MHz -3dB bandwidth

• 50MHz 0.1dB bandwidth

• Fixed gain of 2 output buffer

• Charge pump power down function (0.1mA typical)

• Outputs are high impedance in power-down mode

• Amplifier enable/disable function control

• Pb-free plus anneal available (RoHS compliant)

Applications

• Driving video

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
