Video crosspoint switches more in one
The ISL59532 is billed as the industry's first 32 x 32 video crosspoint switch.
New from Intersil, the ISL59532 is billed as the industry's first 32 x 32 video crosspoint switch The device integrates the four separate 16 x 16 crosspoint switches currently used, to create a 32 x 32 matrix (or two 32 x 16 switches)

Ultra-low-power MOSFETs prolong battery life
Intersil has launched its advanced new DenseTrench power MOSFET family of discrete power devices designed for higher-efficiency low-voltage power switching applications.
Programmable up-converter simplifies basestations
Intersil has added a new highly integrated quad up-convertor to its CommLinkT family of digital radio ICs for fixed basestation applications.
Further reducing board space and costs, the ISL59532 has an integrated DC-restore clamp on every input.
Each output of the device has a fast OSD (on-screen display) switch, again reducing the need for extra silicon around the device.
The ISL59532 features 320MHz bandwidth, 0.1dB flatness to 50MHz, a crosstalk figure of -85dB at 6MHz and a differential gain and phase of 0.025%/0.05 degree.
The device is ideal for security video, video switchers and routers, KVM (keyboard, video, mouse), broadcast video and other video applications.
The ISL59532 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, and all using the same footprint, making it easy to scale designs up or down.
Additionally, system level design is made easier by several features of the ISL59532.
The gain of the output amplifiers can be individually programmed to a gain of +1 or +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.
With the ISL59532, Intersil is the first in the industry to offer this level of integration.
The device 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.
Additionally, the IS59532 has very little crosstalk (-85dB), a significant improvement over competitive devices in the industry.
The ISL59532 is available now in 356-pin BGA (ball grid array) package.
