TX-IDLE-SET-TO-IDLE
Max time to transition to idle VIN = 1Vpp, 10 Gbps 6.5 ns
after differential signal EQ = 00, DE = 0
T
TX-IDLE-TO-DIFF-DATA
Max time to transition to valid VIN = 1Vpp, 10 Gbps 3.2 ns

(4) Force +/- 100 uA on output, measure delta V on the Output and calculate impedance. Mismatch is the percentage difference of OUTn+
and OUTn- impedance driving the same logic state.
(5) Default VOD used for testing. DE = -1.5 dB level used to compensate for fixture attenuation.
