Level II Medium Run Receiver Specifications

1. DC coupling compliance is optional (Load Type 1). Only receivers that support DC coupling are required to meet this

parameter.

2. Load Type 0 with min T_Vdiff, AC-Coupling or floating load. For floating load, input resistance must be > 1K Ohm.

3. For Load Type 1: T_Vtt and R_Vtt = 1.2V +5% / -8%.
