Description
SM100GSB-20A Copper Small Form Pluggable
(SFP) transceivers are based on the SFP Multi Source Agreement (MSA).
They are compatible with the Gigabit Ethernet and 1000BASE-T standards
as specified in IEEE Std 802.3 . The 1000BASE-T physical layer IC (PHY)
can be accessed via I2C, allowing access to all PHY settings and features.
The 1000BASE-T uses the SFP's RX_LOS pin for link indication. If pull up
SFP's TX_DISABLE pin, PHY IC be reset..

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.

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.
