Unit Notes

3. This parameter is dependent on the Ethernet clock frequency. The delay is equal to 5 Ethernet clock periods ± 3 ns. For

example, with an Ethernet clock of 400 MHz, the min/max delay is 12.5 ns ± 3 ns.

4. tenet_clk is the Ethernet clock period (Frame Manager clock period).

5. For recommended operating conditions, see Table 3.
