32 x 16 Nonblocking Video Crosspoint Switch

with On-Screen Display Insertion and I/O Buffers

General Description

Features

✕ 32 16 Nonblocking Matrix with Buffered Inputs

and Outputs

The MAX4358 is a 32 ✕ 16 highly integrated video

crosspoint switch matrix with input and output buffers

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

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

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

pendent single +2.7ꢀ to +5.5ꢀ supply. Individual

outputs can be switched between an input video signal

source and OSD information through an internal, dedi-

cated fast 2:1 mux (40ns switching times) located

before the output buffer. All inputs and outputs are

buffered, with all outputs able to drive standard 75Ω

reverse-terminated video loads.

✕ Operates from a ±3V, ±5V, or +5V Supply

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

✕ Each Output Individually Addressable

✕ Individually Programmable Output Buffer Gain

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

✕ High-Impedance Output Disable for Wired-OR

Connections

The switch matrix configuration and output buffer gain

are programmed through an SPI/QSPI™-compatible,

three-wire serial interface and initialized with a single

update signal. The unique serial interface operates in

two modes facilitating both fast updates and initializa-

tion. On power-up, all outputs are initialized in the dis-

abled state to avoid output conflicts in large-array

configurations.

Superior flexibility, high integration, and space-saving

packaging make this nonblocking switch matrix ideal

for routing video signals in security and video-on-

demand systems.

✕ 0.1dB Gain Flatness to 12MHz

✕ Minimum -62dB Crosstalk, -110dB Isolation at

6MHz

✕ 0.05%/0.1° Differential Gain/Differential Phase

Error

✕ Low 195mW Power Consumption (0.38mW per

point)
