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°, 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™-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°C to +85°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.
