Dual Channel, Single Supply Video

Reconstruction Filter with Charge Pump

The ISL59832 is a dual channel, single supply video driver

with reconstruction filter and charge pump. It is designed to

drive SDTV displays with S-Video (Y/C) signals. It operates

on a single supply (3.0V to 3.6V) and generates its own

negative supply (-1.5V) using a regulated charge pump.

Input signals can be AC- or DC-coupled. When AC-coupled,

the sync tip clamp sets the blank level to ground at the

output of Channel 1 thus ensuring that the sync-tip voltage

level is set to approximately -300mV at the back-termination

resistor of a standard video load. Channel 1 also has a sync

detector whose output is available at SYNC_OUT pin. In a

typical application where the luma is connected to

Channel 1, and chrominance is connected to Channel 2,

SYNC_IN is connected to SYNC_OUT thus providing timing

to Channel 2. Channel 2 has a keyed clamp which sets the

output to ground when SYNC_IN is driven to the logic high

state. The ISL59832 is capable of driving two DC- or

AC-coupled standard video loads. The ISL59832 features a

9MHz nominal -3dB frequency and 40dB of attenuation at

27MHz. Nominal operational current is 31mA. When

powered down, the device draws 1µA maximum supply

current. The ISL59832 is available in 16 Ld TQFN package.

Ordering Information

NOTE: These Intersil Pb-free plastic packaged products employ

special Pb-free material sets, molding compounds/die attach

materials, and 100% matte tin plate plus anneal (e3 termination finish,

which is 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.
