Description
The LCP-155xxxx series is a hot pluggable 3.3V
Small-Form-Factor transceiver module designed
expressly for high-speed communication
applications that require rates of up to
155Mbit/sec. It is compliant with the ATM,
SONET OC-3/SDH STM-1 standards, as well as
the SFP Multisource Agreement (MSA).
The LCP-155xxxx transceivers provide with the
LC receptacle that is compatible with the
industry standard LC connector. The transceiver
is also compatible with industry standard RFT
connector and cage.
The post-amplifier of the LCP-155xxxx also
includes a LOS (Loss Of Signal) circuit that
provides a TTL logic-high output when an
unusable optical signal level is detected.
The LCP-155xxxx transceiver is a Class 1 eye
safety product. The optical power levels, under
normal operation, are at eye safe level.

Notes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10K 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 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 – 10Kresistor 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 – 10K 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 100 differential lines which should be
terminated with 100 (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 300 mA. Recommended host board power supply filtering is shown
below. Inductors with DC resistance of less than 1Ω 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 30 mA 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 100
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.
