4.4.3.14
The eTSEC3 protocol inputs, shown in
the eTSEC3 controller. Note that the value latched on these signals during POR is accessible through the
memory-mapped PORDEVSR (POR device status register) described in
Status Register (PORDEVSR).”
4.4.3.15
As shown in
clock--either a 100MHz or 125MHz LVDS differential clock. This one clock is applied to an internal PLL
whose output creates the clock used by all four SGMII SerDes lanes. The result is always a 1.25Gbaud
transmission/receive rate on each lane. Note that the value latched on this signal is accessible through the
memory-mapped SerDes Control and Status Register described in
Register 3
