... Receiver Byte Clocks. Two 180 degrees out-of-phase 62.5 MHz clock signals that are recovered by the receiver section. The received bytes are alternately clocked by the rising edges of these signals. The rising edge of RX_CLK<1> aligns with a comma character when detected. 4 PI90SD1636A SERDES Gigabit Ethernet Transceiver PS8641 10/14/04 ...
