Description
www.DataSheet4U.com
The LCP-2125 series are hot pluggable 3.3V Applications
Small-Form-Factor transceiver modules designed z Switch to Switch interface
expressly for high-speed communication z Switched backplane applications
applications that require rates up to 2.125Gb/s.
The transceiver is data rate transparent, which z File server interface
means it can support 2x Fiber channel as well as
GbE (1.25Gb/s) and 1x Fiber channel (1.062Gb/s).
Performance
The LCP-2125 series are designed to be z LCP-2125A4EDR Data Link up to 300m in
compliant with SFF-8472 SFP Multi-source
Agreement (MSA) with digital monitoring functions:
50/125μm Multi Mode Fiber
Temperature, VCC, TX optical power, TX laser bias
current, and RX received optical power.
The post-amplifier of the LCP-2125 series also
includes a Loss of Signal (LOS) circuit that
provides a TTL logic-high output when the received
optical level is bellow a preset LOS Assert
threshold.

1 page Notes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor on the host
board. Pull up voltage between 2.0V and VccT, R+0.3V. When high, output indicates a laser fault of some kind.
Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
2) TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module
with a 4.7 – 10 K Ω resistor. Its states are:
Low (0 – 0.8V):
Transmitter on
(>0.8, < 2.0V):
Undefined
High (2.0 – 3.465V): Transmitter Disabled
Open:
Transmitter Disabled
3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K – 10KΩresistor on the
host board. The pull-up voltage shall be VccT or VccR (see Section IV for further details). Mod-Def 0 is grounded
by the module to indicate that the module is present Mod-Def 1 is the clock line of two wire serial interface for
serial ID Mod-Def 2 is the data line of two wire serial interface for serial ID
4) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor.
Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates the received optical power is
below the worst-case receiver sensitivity (as defined by the standard in use). Low indicates normal operation. In
the low state, the output will be pulled to < 0.8V.
5) VeeR and VeeT may be internally connected within the SFP module.
6) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be
terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus
not required on the host board. The voltage swing on these lines will be between 370 and 2000 mV differential
(185 – 1000 mV single ended) when properly terminated.
7) VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% at the SFP
connector pin. Maximum supply current is 300mA. Recommended host board power supply filtering is shown
below. Inductors with DC resistance of less than 1=should be used in order to maintain the required voltage at the
SFP input pin with 3.3V supply voltage. When the recommended supply-filtering network is used, hot plugging of
the SFP transceiver module will result in an inrush current of no more than 30mA greater than the steady state
value. VccR and VccT may be internally connected within the SFP transceiver module.
8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω
differential termination inside the module. The AC coupling is done inside the module and is thus not
required on the host board. The inputs will accept differential swings of 500 – 2400 mV (250 – 1200
mV single-ended), though it is recommended that values between 500 and 1200 mV differential (250 –
600 mV single-ended) be used for best EMI performance.
