Note 2: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 3: Defined as differential output to single-ended input.
Note 4: Input is AC-coupled.
Note 5: The RC time constant (3Hz) formed by the source resistance (RS) and coupling capacitor (CIN) is usually used for lead
compensation of the active clamp. The source resistance is 400Ω max. The clamp should remain stable in this condition.
Note 6: Differential mode is defined as (OUT+ - OUT-). Common mode is defined 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 defined as 20log((OUT+ - OUT-) / (OUT+ + OUT-)).
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.
