(2) Based on characterization data over the full range of recommended operating conditions of the device. Jitter is measured in accordance
with SMPTE RP 184, SMPTE RP 192, and the applicable serial data transmission standard: SMPTE 424M, SMPTE 292M, or SMPTE
259M.
(3) Measured with Pseudo Matrix Pathological test signal.
(4) Specification is ensured by characterization.
(5) Input return loss is dependent on board design. The LMH0344 exceeds this specification on the SD344 evaluation board with a return
loss network consisting of an 8.2 nH inductor in parallel with a 0.5 pF capacitor in parallel with the 75Ω series resistor on the input.
