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
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
specified over an extended -40°C to +85°C temperature
range.
The ISL59530 is a single-ended input version of this device.
For capacitor-coupled applications, the ISL59530 inputs
include a clamp circuit that restores the input level to an
externally applied reference.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
