ISL59531

® ISL59531 Data Sheet March 21, 2006 FN6251.0 PRELIMINARY 16x16 Video Crosspoint with Differential Inputs The ISL59531 is a 16x16 integrated video crosspoint switch matrix with differential input and On-Screen Display (OSD) insertion. The ISL59531 is ideal for routing video signals in security and video-on-demand systems. This device operates from a single +5V supply. Any output of the 16 video inputs cable can be switched to any of the 16 outputs. OSD information can be inserted into any output through an internal, dedicated fast 2:1 mux (15ns switching times) located before the output buffer. Also, any input can be broadcast to all 16 outputs. Each output can be tri-stated and its gain set to +1 or +2 through the SPI interface. The ISL59531 offers a -3dB signal bandwidth of 320MHz. The differential gain and differential phase of 0.025%, along with 0.1dB flatness out to 50MHz, making the ISL59531 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 ISL59531 interface is set up to facilitate both fast updates and initialization. On power-up, all outputs are initialized in the disabled state to avoid output conflicts www.DataSheet4U.com within the user system. The ISL59531 has single-supply signal operation. It can accommodate input common mode voltages from 0V to 3.5V and 0V to 4V at the outputs. The ISL59531 is available in a 356-pin BGA package and spec...
