Data at DIN is clocked on
negative edge of SCLK into 112-
bit Complete Matrix Mode
register. DOUT supplies original
data in 112 SCLK pulses later.

Data in serial 112-bit Complete
Matrix Mode register is

which control the switching
matrix.

Data at DIN is routed to
Individual Output Address Mode
shift register. DIN is also
connected directly to DOUT so
that all devices on the serial bus
may be addressed in parallel.

4-bit chip address A3–A0 is
compared to D14–D11. If equal,
remaining 11 bits in Individual
Output Address Mode Register
are decoded, allowing
reprogramming for a single
output.
AOUT signals successful
individual matrix update.

Asynchronous reset. All outputs
are disabled. Other logic remains
unchanged.
Analog Inputs
The MAX4358 offers 32 analog input channels. Each
input is buffered before the crosspoint matrix switch,
allowing one input to cross-connect up to 16 outputs.
The input buffers are voltage feedback amplifiers with
high-input impedance and low input bias current. This
allows the use of very simple input clamp circuits.
OSDFILL and OSDKEY Inputs
Intended for on-screen display insertion, the 16 OSD-
FILL inputs are buffered analog signal inputs that are
routed to a dedicated output buffer through a fast 2:1
MUX. The signal presented to the output buffer is
selected from the programmed analog input signal
(IN_) and the dedicated OSDFILL input signal.
Switch Matrix
The MAX4358 has 512 individual T-switches making a
32 16 switch matrix. The switching matrix is 100%
nonblocking, which means that any input may be rout-
ed to any output. The switch matrix programming is
output-referred. Each output may be connected to any
one of the 32 analog inputs. Any one input can be rout-
ed to all 16 outputs with no signal degradation.
Digital Interface
The digital interface consists of the following pins: DIN,
DOUT, SCLK,
AOUT, UPDATE, CE, A3–A0, MODE, and
RESET. DIN is the serial-data input, DOUT is the serial-
data output.
