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.

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.

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.
