Notes:

1. Clock tolerance is ±50 ppm

2. By default, the SFP‑AG‑CO‑02 is a full duplex device in preferred master mode

3. Automatic crossover detection is enabled. External crossover cable is not required

4. 10/100/1000 BASE‑T operation requires the host system to have an SGMII interface with no clocks, with a SERDES that does not support SGMII, the module will operate at 1000BASE‑T only.
