Notes:

1. In general, the clock reference symbol for this section is based on the symbols RGT to represent RGMII and RTBI timing. For

example, the subscript of t

RGT

represents the TBI (T) receive (RX) clock. Also, the notation for rise (R) and fall (F) times

follows the clock symbol. For symbols representing skews, the subscript is SK followed by the clock being skewed (RGT).

2. This implies that PC board design requires clocks to be routed so that an additional trace delay of greater than 1.5 ns is added

to the associated clock signal.

3. For 10 and 100 Mbps, t

RGT

scales to 400 ns ± 40 ns and 40 ns ± 4 ns, respectively.

4. Duty cycle may be stretched/shrunk during speed changes or while transitioning to a received packet clock domains as long

as the minimum duty cycle is not violated and stretching occurs for no more than three t

RGT

of the lowest speed transitioned.

5. Duty cycle reference is LV

/2.
