Description
SM 10GL Copper Small Form Pluggable (SFP) transceivers are based on
the SFP Multi Source Agreement (MSA) . They are compatible with the
10Gbase-T / 5Gbase-T / 2.5Gbase-T / 1000base-T standards as specified
in IEEE Std 802.3 . SM 10GL uses the SFP's RX_LOS(must be pulled up on
host) pin for link indication. If pull up or open SFP's TX_DISABLE pin,
PHY IC be reset.

+3.3V Volt Electrical Power Interface
The SM 10GL has an input voltage range of 3.3 V +/- 5%. The 4V
maximum voltage is not allowed for continuous operation.

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.
