FIFO, GMII, MII, TBI, RGMII, RMII, and RTBI AC Timing
Specifications
The AC timing specifications for FIFO, GMII, MII, TBI, RGMII, RMII and RTBI are presented in this
section.
8.2.1
FIFO AC Specifications
The basis for the AC specifications for the eTSEC’s FIFO modes is the double data rate RGMII and RTBI
specifications because they have similar performance and are described in a source-synchronous fashion
like FIFO modes. However, the FIFO interface provides deliberate skew between the transmitted data and
source clock in GMII fashion.
When the eTSEC is configured for FIFO modes, all clocks are supplied from external sources to the
relevant eTSEC interface. That is, the transmit clock must be applied to the eTSECn’s TSECn_TX_CLK,
while the receive clock must be applied to pin TSECn_RX_CLK. The eTSEC internally uses the transmit
