2.PRODUCT DESCRIPTION
BDTR-FB-P1RC Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) . They are compatible with the 100base-T copper SFP module standards as specified in IEEE Std 802.3 . BDTR-FB-P1RC uses the SFP's RX_LOS pin for link indication. If pull up SFP's TX_DISABLE pin, SWITCH IC be reset.

Notes:
- Circuit ground is connected to chassis ground
- PHY disabled on TDIS > 2.0V or open, enabled on TDIS< 0.8V
- 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.
- LVTTL compatible with a maximum voltage of 2.5V.
