Notes:

1. Circuit ground is connected to chassis ground

2. PHY disabled on TDIS > 2.0V or open, enabled on TDIS < 0.8V

3. Should be pulled up with 4.7k - 10k Ohms on host board to a voltage between 2.0 V and 3.6 V. MOD_DEF(0) pulls line low to indicate module is plugged in.

4. LVTTL compatible with a maximum voltage of 2.5V.

Not supported on 10/100/1000BASE-T.

+3.3V Volt Electrical Power Interface

The SFP-1000BASE-T/SFP-1000BASE-T-SGMII has an input voltage range of 3.3 V +/- 5%.

The 4V maximum voltage is not allowed for continuous operation.

+3.3 Volt Electrical Power Interface

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.

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.

Serial Communication Protocol

All SFPs support the 2-wire serial communication protocol outlined in the

SFP MSA. These SFPs use an MCU, can be accessed with address of A0h.

The 1000BASE-T physical layer IC can also be accessed via the 2-wire serial bus

at address ACh. For details interfacing with the PHY IC, see Marvell data sheet

titled "Alaska Ultra 88E1111 Integrated Gigabit Ethernet Transceiver"

(Marvell document number MV-S100649-00).
