AC ELECTRICAL CHARACTERISTICS—MAX9546 Driving MAX9547

+25°C, unless otherwise noted.) (Note 2)

Note 2:

Note 3:

Defined as differential output to single-ended input.

Note 4:

Input is AC-coupled.

Note 5:

compensation of the active clamp. The source resistance is 400Ω max. The clamp should remain stable in this condition.

Note 6:

Differential mode is measured as (OUT+ - OUT-). Common mode is measured as OUT+ + OUT-

2

Note 7:

A fault is when the outputs both sink and source current and the amount of extra current sink or source is greater than 3mA.

Note 8:

Common-mode balance is measured as 20log((OUT+ - OUT-) / (OUT+ + OUT-)).

2

Note 9:

Ground between MAX9546 and MAX9547 can be a ±2V difference.

Note 10: A loss-of-signal is when the input video signal of the MAX9547 does not change (cross 100mV level from sync tip) for 10

video lines.

Note 11: Input capacitor for this test is 0.33µF.
