2.6.3.6
The following table shows the TBI single-clock mode receive AC timing specifications.
For recommended operating conditions, see
The following figure shows the TBI single-clock mode receive AC timing diagram.
2.6.3.7
The following table presents the RGMII and RTBI AC timing specifications.
Freescale Semiconductor
For recommended operating conditions, see
RX_CLK clock period
RX_CLK duty cycle
RX_CLK peak-to-peak jitter
Rise time RX_CLK (20%–80%)
Fall time RX_CLK (80%–20%)
RCG[9:0] setup time to RX_CLK rising edge
RCG[9:0] hold time to RX_CLK rising edge
Note:
1. The frequency of RX_CLK should not exceed the frequency of gigabit Ethernet reference clock by more than 300 ppm.
2. System/board must be designed to ensure the input requirement to the device is achieved. Proper device operation is
Data to clock output skew (at transmitter)
Data to clock input skew (at receiver)
Clock period duration
Duty cycle for 10BASE-T and 100BASE-TX
guaranteed for inputs meeting this requirement by design, simulation, characterization, or functional testing.
