(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) LMH0387 equalizer launch amplitude fine tuning set to nominal via the SPI by writing 30h (“00110000 binary”) to SPI register 02h. (4) Specification is ensured by characterization. (5) Return loss is dependent on board design. The LMH0387 exceeds this specification on the SD387 evaluation board.
