Note 6: The differential output voltage and offset voltage are adjustable via the SPI.
Note 7: The equalizer automatically shifts equalization stages at cable lengths less than 140m (Belden 1694A) to reduce power consumption. This power savings
is also achieved by setting Extended 3G Reach Mode = 1 via the SPI.
Note 8: 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.
Note 9: Input return loss is dependent on board design. The LMH0384 exceeds this specification on the SD384 evaluation board with a return loss network
consisting of a 5.6 nH inductor in parallel with the 75Ω series resistor on the input.
