6.1.4.1. GMII Clock Signals
Name | I/O | Description |
---|---|---|
rx_clk_125 | I | 125 MHz receive clock for the RX datapath on MAC side |
tx_clk_125 | I | 125 MHz transmit clock for the TX datapath on MAC side. |
rx_clk_62_5 | I | 62.5 MHz receive clock for the RX datapath on PCS side. Intel® recommends that this clock and rx_clk_125 share the same clock source. This clock must be synchronous to rx_clk_125. Their rising edges must align and must have 0 ppm and phase shift. |
tx_clk_62_5 | I | 62.5 MHz transmit clock for the TX datapath on PCS side. Intel® recommends that this clock and tx_clk_125 share the same clock source. This clock must be synchronous to tx_clk_125. Their rising edges must align and must have 0 ppm and phase shift. |
