FN6267.1
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
4th order Butterworth reconstruction filter that provides 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.
