USXGMII SFP+ RJ45 电口模块

PRODUCT DESCRIPTION
SFP+-10GBASE-T 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 . SFP+-10GBASE-T 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. PHY disabled on TDIS > 2.0V or open, enabled on TDIS < 0.8V
2. 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.
