Fe a t u re s

The MAX4356 is a 16 ✕ 16 highly inte gra te d vide o

crosspoint switch matrix with input and output buffers

and On-Screen Display (OSD) Insertion. This device

operates from dual ±3V to ±5V supplies or from a sin-

gle +5V supply. Digital logic is supplied from an inde-

p e nd e nt s ing le + 2.7V to + 5.5V s up p ly. Ind ivid ua l

outputs can be switched between an input video signal

source and OSD information through an internal, dedi-

c a te d fa s t 2:1 mux (40ns s witc hing time s ) loc a te d

before the output buffer. All inputs and outputs are

buffered, with all outputs able to drive standard 75Ω

reverse-terminated video loads.

✕ 16 16 Nonblocking Matrix with Buffered Inputs

and Outputs

✕ Operates from ±3V, ±5V, or +5V Supplies

✕ Individually Programmable Output Buffer Gain

(A = +1V/V or +2V/V)

✕ High-Impedance Output Disable for Wired-OR

Connections

✕ Fast-Switching (40ns) 2:1 OSD Insertion Mux

✕ 0.1dB Gain Flatness to 14MHz

The switch matrix configuration and output buffer gain

are programmed via an SPI/QSPI^™-compatible, three-

wire serial interface and initialized with a single update

s ig na l. The uniq ue s e ria l inte rfa c e op e ra te s in two

modes facilitating both fast updates and initialization.

On power-up, all outputs are initialized in the disabled

state to avoid output conflicts in large-array configura-

tions.

✕ -62dB Crosstalk, -110dB Isolation at 6MHz

✕ 0.02%/0.12° Differential Gain/Differential Phase

Error

✕ Low 195mW Power Consumption (0.76mW per

Point)

Superior flexibility, high integration, and space-saving

packaging make this nonblocking switch matrix ideal

for routing vid e o s ig na ls in s e c urity a nd vid e o-on-

demand systems.
