ISL59532

Data Sheet

February 7, 2007

FN7432.5

32x32 Video Crosspoint

The ISL59532 is a 300MHz 32x32 Video Crosspoint Switch.

Each input has an integrated DC-restore clamp and an input

buffer. Each output has a fast On-Screen Display (OSD)

switch (for inserting graphics or other video) and an output

buffer. The switch is non-blocking, so any combination of

inputs to outputs can be chosen, including one channel

driving multiple outputs. The Broadcast Mode directs one

input to all 32 outputs. The output buffers can be individually

controlled through the SPI interface, the gain can be

programmed to x1 or x2, and each output can be placed into

a high impedance mode.

The ISL59532 offers a typical -3dB signal bandwidth of

300MHz. Differential gain of 0.025% and differential phase of

0.05擄, along with 0.1dB flatness out to 50MHz, make the

ISL59532 suitable for many video applications.

The switch matrix configuration and output buffer gain are

programmed through an SPI/QSPI鈩?compatible three-wire

serial interface. The ISL59532 interface is designed to

facilitate both fast updates and initialization. On power-up, all

outputs are high impedance to avoid output conflicts.

The ISL59532 is available in a 356 ball BGA package and

specified over an extended -40擄C to +85擄C temperature range.

The single-supply ISL59532 can accommodate input signals

from 0V to 3.5V and output voltages from 0V to 3.8V. Each

input includes a clamp circuit that restores the input level to

an externally applied reference in AC-coupled applications.

The ISL59533 is a fully differential input version of this device.

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.
