Note 1: AC specifications are guaranteed by design and characterization.

Note 2: Differential voltage is defined as VP-P = (V+ - V-). Inputs and outputs must be AC-coupled for proper operation.

Note 3: Output transition time measured using a 0000011111 pattern, with transmit PE off.

Note 4: Transmit PE compensates for 20in of 6-mil-wide differential stripline in FR-4 or equivalent path loss.

Note 5: Jitter after paths from RX to OUT_ or IN_ to TX. Measured with no jitter on the input, using a ±K28.5 pattern, and a path con-

sisting of the MAX3786 alone.

Note 6: Jitter after EQ for the paths from RX to OUT_ or IN_ to TX. Measured with no jitter on the input, using a ±K28.5 pattern, and a

path consisting of the MAX3786 plus 20in of 6-mil-wide differential stripline in FR-4 on the output.

Note 7: Total time for LOS to enable/disable the outputs.

Note 8: Measured with a 100mV sinusoidal common-mode signal in the 2MHz ≤ f ≤ 200MHz range.

(VCC = 3.3V, TA = +25°C, unless otherwise noted.)
