FCLF8520P2BTL, FCLF8521P2BTL and FCLF8522P2BTL 1000BASE-T SFP Product Specification
II.
The FCLF8520P2BTL, FCLF8521P2BTL and FCLF8522P2BTL have an input voltage range of 3.3 V +/- 5%. The 4 V
maximum voltage is not allowed for continuous operation.

Caution: Power consumption and surge current are higher than the specific values in the SFP MSA
III. Low-Speed Signals
MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA), are open drain CMOS signals (see section VII, “Serial
Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2) must be pulled up to host_Vcc.
