Due to SMPTE naming convention, all SMPTE Engineering Documents will be numbered as a two-letter prefix and a number.

Documents and references with the same root number and year are functionally identical; for example ST 424-2006 and SMPTE 424M-

2006 refer to the same document.

(3)

Based on characterization data over the full range of recommended operating conditions of the device. Jitter is measured in accordance

with RP 184, RP 192, and the applicable serial data transmission standard: ST 424, ST 292, or ST 259.

(4)

Measured with Pseudo Matrix Pathological test signal.

(5)

Specification is ensured by characterization.

(6)

Input return loss is dependent onboard 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 75

Ω series resistor on the input.
