5.2.2.8.1Clock Rates

The TFCLK and RFCLK can be independent of each other in SPHY mode operation. TFCLK and RFCLK should be common to all the Network Processor devices. The IXF1104 MAC requires an individual single clock source for the device transmit path and a single clock source for the device receive path.

The IXF1104 MAC allows this interface to be overclocked so that all four IXF1104 MAC ports can operate at 1 Gbps. This allows data transfer at data rates of up to 4.0 Gbps when operating at an overclocked frequency of 125 MHz.

Note: SPHY operates at a maximum frequency of 125 MHz.
