7-2 | SEL EMP LANE x (where x = 1, 0, 2, or 3) | R/W | 0h | These bits select the amount of de-emphasis for the JESD output transmitter. The de-emphasis value in dB is measured as the ratio between the peak value after the signal transition to the settled value of the voltage in one bit period. 000000 = 0 dB 000001 = –1 dB 000011 = –2 dB 000111 = –4.1 dB 001111 = –6.2 dB 011111 = –8.2 dB 111111 = –11.5 dB |
