MAXIM MAX4358 User Manual

General Description
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 ±3V to ±5V supplies or from a sin­gle +5V supply. Digital logic is supplied from an inde­pendent single +2.7V to +5.5V supply. Individual outputs can be switched between an input video signal source and OSD information through an internal, dedi­cated 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 75 reverse-terminated video loads.
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 initializa­tion. On power-up, all outputs are initialized in the dis­abled 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-on­demand systems.
The MAX4358 is available in a 144-pin TQFP package and specified over an extended -40°C to +85°C tem­perature range. The MAX4358 evaluation kit is available to speed designs.

, unless otherwise noted.
Typical values are at TA= +25°C. )
Note 1: Associated output voltage may be determined by multiplying the input voltage by the specified gain (A
V
)
and adding output
offset voltage. Gain is specified for IN_ and OSDFILL_ signal paths.
Note 2: Logic level characteristics apply to the following pins: DIN, DOUT, SCLK, CE, UPDATE, RESET, A3–A0, MODE, AOUT, and
OSDKEY_.
Note 3: Switching transient settling time is guaranteed by the settling time (t
S
) specification. Switching transient is a result of updat-
ing the switch matrix.
Note 4: Input test signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0 to 100IRE). IRE is a unit of
video-signal amplitude developed by the International Radio Engineers: 140IRE = 1.0V.
Note 5: All devices are 100% production tested at +25°C. Specifications over temperature limits are guaranteed by design.

Naming Conventions:
• All parameters with time units are given “t” designation, with appropriate subscript modifiers.
• Propagation delays for clocked signals are from active edge of clock.
• Propagation delay for level sensitive signals is from input to output at 50% point of a transition.
• Setup and Hold times are measured from 50% point of sig­nal transition to 50% point of clocking signal transition.
• Setup time refers to any signal that must be stable before active clock edge, even if signal is not latched or clocked itself.
• Hold time refers to any signal that must be stable during and after active clock edge, even if signal is not latched or clocked.
• Propagation delays to unobservable internal signals are modified to setup and hold designations applied to observ­able IO signals.
