FCMJ-8520/8521-3 1000BASE-T SFP Product Specification
II.
The FCMJ-8520/8521-3 has an input voltage range of 3.3 V +/- 5%. The 4 V maximum
voltage is not allowed for continuous operation.
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.
