AC ELECTRICAL CHARACTERISTICS—MAX9546 Driving MAX9547
(VCC = +8.5V, RL = 220 across OUT+ and OUT-, RL = 75 (MAX9547), ZZT = 75, TA = -40°C to +85°C. Typical values are at TA =
+25°C, unless otherwise noted.) (Note 3)
Note 3:
All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 4:
Defined as differential output to single-ended input.
Note 5:
Input is AC-coupled.
Note 6:
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 400 max. The clamp should remain stable in this condition.
Note 7:
Differential mode is measured as (OUT+ - OUT-). Common mode is measured as OUT+ + OUT-
2
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.
Note 9:
Common-mode balance is measured as 20log((OUT+ - OUT-) / (OUT+ + OUT-)).
2
Note 10: These results were measured with a MAX4144 receiver, other receivers may affect results.
Note 11: Ground between MAX9546 and MAX9547 can be a ±2V difference.
Note 12: 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 13: These results were measured with a MAX4447 transmitter and a MAX4012 buffer amplifier with a gain of 4. Using other
devices may affect results.
Note 14: MAX9547 topology shown in Figure 3.
Note 15: Input capacitor for this test is 0.33F.
