Crosspoint switch routes video signals

Milpitas, Calif. — Intersil Corp.'s video crosspoint switch is said to be the first of its kind — integrating four separate 16 x 16 crosspoint switches to create a 32 x 32 matrix (or two 32 x 16 switches).

The ISL59532 32 x 32 video crosspoint switch features 320-MHz bandwidth, crosstalk of -85 dB at 6 MHz, 0.025 percent differential gain and 0.05 degrees differential phase.

The crosspoint switch has an integrated DC-restore clamp on every input and each output has a fast onscreen display (OSD) switch. Applications include security video, video switchers and routers, keyboard, video, mouse (KVM), broadcast video and other video applications.

The ISL59532 switch is the first in a family of parts that will include 32 x16 and 16 x 16 switches, all with single-ended input and differential input versions, all using the same footprint. The gain of the output amplifiers can be individually programmed to a gain of plus 1 or plus 2 through the SPI interface. The same interface can be used to place any output into a high impedance tri-state, so that several 32 x 32 crosspoint switches can be linked together, creating even larger matrices.

“The ISL59532 has higher integration than competitive devices, both with the number of input and output channels in one package, but also with its additional functions, such as DC-restore and its fast OSD switch,” said Kathryn Tucker, marketing manager for Intersil's video products group.

The ISL59532 is available now in 356-pin BGA package and is priced at $105.00 in 1,000-unit quantities. Click here for the ISL59532 data sheet.
