The ISL59533 is a 32x32 integrated video crosspoint switch matrix with input and output buffers and On-Screen Display (OSD) insertion. The ISL59533 is ideal for routing video signals in security and video-on-demand systems. This device operates from a single +5V supply. Any output can be switched to any of the 32 input video signal sources and OSD information through an internal, dedicated fast 2:1 mux (15ns switching times) located before the output buffer. Also, any one input can be broadcast to all 32 outputs.
The ISL59533 offers a -3dB signal bandwidth of 300MHz. The differential gain and phase at 0.01% and 0.03° respectively, along with 0.1dB flatness out to 35MHz, make the ISL59533 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 ISL59533 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 within the user system.
The ISL59533 is available in a 356-pin BGA package and specified over an extended -40°C to +85°C temperature range.
The ISL59533 has single-supply signal operation. It can accommodate input and output voltages from ground to >3.5V. It also has fully differential inputs. The differential input span is ±1.5V. The output offset is applied via a group reference input. |
