3 / 7 page FCLF-8520/8521-3 1000BASE-T SFP Product Specification Finisar II. +3.3V Volt Electrical Power Interface The FCLF-8520/8521-3 has an input voltage range of 3.3 V +/- 5%. The 4 V maximum voltage is not allowed for continuous operation. +3.3 Volt Electrical Power Interface Parameter Symbol Min Typ Max Units Notes/Conditions Supply Current Is 320 375 mA 1.2W max power over full range of voltage and temperature. See caution note below Input Voltage Vcc 3.13 3.3 3.47 V Referenced to GND Maximum Voltage Vmax 4 V Surge Current Isurge 30 mA Hot plug above steady state current. See caution note below Caution: Power consumption and surge current are higher than the specified values in the SFP MSA Table 2. +3.3 Volt electrical power interface 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.
