SERDES High Speed Data Receiver
Table 3-9. Serial Input Data Specifications
Input Data Jitter Tolerance
A receiver’s ability to tolerate incoming signal jitter is very dependent on jitter type. High speed serial interface stan-
dards have recognized the dependency on jitter type and have specifications to indicate tolerance levels for differ-
ent jitter types as they relate to specific protocols. Sinusoidal jitter is considered to be a worst case jitter type.

1. This is the number of bits allowed without a transition on the incoming data stream when using DC coupling.
2. This is the typical number of bit times to re-lock to a new phase or frequency within +/- 300 ppm, assuming 8b10b encoded data.
3. AC coupling is used to interface to LVPECL and LVDS. LVDS interfaces are found in laser drivers and Fibre Channel equipment. LVDS inter-
