Input Signal: (comply with VESA) Level: 0 to 700mv Positive Rise/Fall time: < 5ns Overshoot: < 10% of maximum transition. Impedance: 75 ± 5% Current Sink and Source When low level is asserted, the maximum current sink from any single monitor sync input node to the driver is 2.0mA. When high level is asserted, the maximum current source from the driver to any single monitor sync input node is 500uA.
