Ethernet: Enhanced Three-Speed Ethernet (eTSEC), MII Management
clock to synchronously generate transmit data and outputs an echoed copy of the transmit clock back out
onto the TSECn_GTX_CLK pin (while transmit data appears on TSECn_TXD[7:0], for example). It is
intended that external receivers capture eTSEC transmit data using the clock on TSECn_GTX_CLK as a
source- synchronous timing reference. Typically, the clock edge that launched the data can be used, since
the clock is delayed by the eTSEC to allow acceptable set-up margin at the receiver. Note that there is
relationship between the maximum FIFO speed and the platform speed. For more information, see
NOTE
The phase between the output clocks TSEC1_GTX_CLK and
TSEC2_GTX_CLK (ports 1 and 2) is no more than 100 ps. The phase
between the output clocks TSEC3_GTX_CLK and TSEC4_GTX_CLK
(ports 3 and 4) is no more than 100 ps.
A summary of the FIFO AC specifications appears in Table 26 and Table 27.
