---|---|---|---|---|
7-6 | EMP_LANE_B[5:4] | R/W | 0h | These bits along with bits 3-0 of register 72h set the de-emphasis for lane B. These bits select the amount of de-emphasis for the JESD output transmitter. The de-emphasis value in decibels (dB) is measured as the ratio between the peak value after the signal transitions to the settled value of the voltage in one bit period. 0 : 0 dB 1 : –1 dB 3 : –2 dB 7 : –4.1 dB 15 : –6.2 dB 31 : –8.2 dB 63 : –11.5 dB Others: Do not use |
