Caution: Power consumption and surge current are higher than the specified values in the SFP MSA
Low‑Speed Signals
MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA), are open drain CMOS signals. Both MOD_ DEF(1) and MOD_DEF(2) must be pulled up to host_Vcc.

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.
