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.

5. +3.3V
Volt Electrical Power Interface

The
BDTR-FB-P1RC has an input voltage range of 3.3 V +/- 5%. The 4V maximum voltage
is not allowed for continuous operation.

+3.3 Volt Electrical Power Interface

Supply Current	Is		–	300	mA	1.0W max power over full range of voltage and temperature. See caution note below
Input Voltage	Vcc	3.13	3.3	3.47	V	Referenced to GND
Maximum Voltage	Vmax			4	V
Surge Current	Isurge		TBD		mA	Hot plug above steady state current. See caution note below

Caution:
Power consumption and surge current are higher than the specified values in the
SFP MSA

6.
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
