(2) Based on design and 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) Specification is ensured by characterization.
(4) Input return loss is dependent on board design. The LMH0394 exceeds this specification on the SD394 evaluation board with a return
loss network consisting of a 5.6 nH inductor in parallel with a 75Ω series resistor on the input.
