The ISL59530 is a 300MHz 16x16 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 16 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 ISL59530 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 ISL59530 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 ISL59530 interface is designed to facilitate both fast updates and initialization. On power-up, all outputs are high impedance to avoid output conflicts.

The ISL59530 is available in a 356 ball BGA package and specified over an extended -40°C to +85°C temperature range.

The single-supply ISL59530 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 ISL59531 is a fully differential input version of this device.
