Note 2:
Note 3:
Note 4:
Note 5:
All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Defined as differential output to single-ended input.
Input is AC-coupled.
The RC time constant (3Hz) formed by the source resistance (R
S
) and coupling capacitor (C
IN
) is usually used for lead
compensation of the active clamp. The source resistance is 400
max. The clamp should remain stable in this condition.
Differential mode is measured as (OUT+ - OUT-). Common mode is measured as OUT+ + OUT-
Note 6:
2
Note 7:
Note 8:
A fault is when the outputs both sink and source current and the amount of extra current sink or source is greater than 3mA.
Common-mode balance is measured as 20log((OUT+ - OUT-) / (OUT+ + OUT-)).

Note 9:
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.
Ground between MAX9546 and MAX9547 can be a ±2V difference.
