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:
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.
