(1) Typical values represent most likely parametric norms at VDD = 2.5V, TA = 25°C., and at the Recommended Operation Conditions at the time of product characterization and are not ensured.
(2) The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not ensured.
(3) Allowed supply noise (mVp-p sine wave) under typical conditions.
(4) Propagation Delay measurements will change slightly based on the level of EQ selected. EQ = 00 will result in the shortest propagation delays.
(5) In GEN3 mode, the output VOD level is not fixed. It will be adjusted automatically based on the VID input amplitude level. The output VOD level set by DEM_x[1:0] in GEN3 mode is dependent on the VID level and the frequency content. The DS100MB203 repeater in GEN3 mode is designed to be transparent, so the TX-FIR (de-emphasis) is passed to the RX to support the PCIe GEN3 handshake negotiation link training.
