General Description
The ISL59531 is a 16x16 integrated video crosspoint switch
matrix with differential input and output buffers and On-
Screen Display (OSD) insertion. This device operates from a
single +5V supply. Any output can be switched to any of the
16 input video signal sources and OSD information through
an internal, dedicated fast 2:1 mux located before the output
buffer. Also, any one input can be broadcast to all 16
outputs.
Each output X is defined as:
Voutx = Avx*(INx-INBx+REF)
Where Avx = 1, or Avx = 2. Note that all REF’s are common
between channels and must be externally well buffered
and/or bypassed.
The ISL59531 offers a -3dB signal bandwidth of 320MHz.
The differential gain and differential phase of 0.025% and
0.05° respectively, along with 0.1dB flatness out to 50MHz.
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 facilities
are initialized in the disabled state to avoid output conflicts
within the user system.
Digital Interface
The ISL59531 uses a simple 3-wire SPI compliant digital
interface to program the outputs. The ISL59531 can support
the clock rate up to 5MHz.
Serial Interface
The ISL59531 is programmed through a three-wire serial
interface. The start and stop conditions are defined by the
ENA signal. While the ENA is low, the data on the SDI (serial
data input) pin is shifted into the 16-bit shift register on the
positive edge of the SCLK (serial clock) signal. The LSB
(bit 0) is loaded first and the MSB (bit 15) is loaded last (see
Table 1). After the full 16-bit data has been loaded, the ENA
is pulled high and the addressed output channel is updated.
The SCLK is disabled internally when the ENA is high. The
SCLK must be low before the ENA is pulled low.
The Serial Timing Diagram and parameters table show the
timing requirements for three-wire signals.
