Notes:

1. Diﬀerential impedance is measured between D_in+ and D_in- over the range 4 MHz to 2 GHz.

2. These are unﬁltered 20% - 80% values measured with a 550 MBd 101010 pattern.

3. Inter-channel Skew is deﬁned for the condition of equal amplitude, zero ps skew input signals.

4. Deterministic Jitter (DJ) is deﬁned as the combination of Duty Cycle Distortion (Pulse-Width Distortion) and Data Dependent Jitter. Determin-

istic Jitter is measured at the 50% signal threshold level using a 3.125 GBd Pseudo Random Bit Sequence of length 2 -1 (PBRS7), or equiva-

lent, test pattern with zero skew between the diﬀerential data input signals.

5. Total Jitter (TJ) includes Deterministic Jitter and Random Jitter (RJ). Total Jitter is speciﬁed at a BER of 10 for the same 3.125 GBd test pat-

-12

tern as for DJ and is measured with all channels operating.

6. The speciﬁed optical output power, measured at the output of a 2meter test cable, will be compliant with IEC 60825-1 Amendment 2, Class

1M Accessible Emission Limits, AEL Regulatory Compliance section.
