Figure 4. SFP Host Board Mechanical Layout
Note
1) Tx Fault is an open collector output that shall be pulled up with a 4.7k - 10kΩ resistor on the host board. Pull
up voltage between 2.0V and VccT+0.3V. When high, output indicates a laser fault of some kind. Low
indicates normal operation.
Tx Fault is asserted when bias current of laser exceeds the factory-calibrated threshold level.
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 4.7kΩ resistor.
3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7k - 10kΩ resistor on
the host board. The pull-up voltage shall be VccT.
Mod-Def 0 indicates 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 output that shall be pulled up with a 4.7k - 10kΩ resistor. Pull up
voltage between 2.0V and VccR+0.3V. Low indicates normal operation.
5) 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.
6) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differen-
tial termination inside the module. The AC coupling is done inside the module and is thus not required on the
host board.

Calibration constants for External Calibration Option, 2 wire address A2h
11. Calibration Calculation (SCP6EC4-GL-#N-xx)
Transceiver temperature: Temperature, T, is given by
T = TSLOPE * TAD + TOFFSET
Where TAD is 16-bit signed 2's complement A/D value at bytes 96-97, TSLOPE is unsigned
fixed-point value at bytes 84-85 and TOFFSET is signed 2's complement value with LSB equal
to 1/256 deg-C at bytes 86-87. The result, T, is 16-bit signed 2's complement value with
LSB equal to 1/256 deg-C.The monitored output is the junction temperature of the diode inside the transceiver,
hence, there is some discrepancy between the output and transceiver case temperature of the point illustrated in
section 3 mechanical dimension.
Supply voltage: Voltage, V, is given by
V = VSLOPE * VAD + VOFFSET
Where VAD is 16-bit unsigned A/D value at bytes 98-99, VSLOPE is unsigned fixed-point
value at bytes 88-89 and VOFFSET is signed 2's complement value with LSB equal to 100 µV at
bytes 90-91. The result, V, is 16-bit unsigned value with LSB equal to 100 µV.
Address #Bytes Name Description

78-79 2 IOFFSET 16-bit signed 2's complement calibration data for laser
bias current. Byte 78 is MSB. Byte 79 is LSB.
80-81 2 TPSLOPE Unsigned fixed-point calibration data for laser output
power. Byte 80 is MSB. Byte 81 is LSB.
82-83 2 TPOFFSET 16-bit signed 2's complement calibration data for laser
output power. Byte 82 is MSB. Byte 83 is LSB.

temperature. Byte 84 is MSB. Byte 85 is LSB.

transceiver temperature. Byte 86 is MSB. Byte 87 is LSB.
88-89 2 VSLOPE Unsigned fixed-point calibration data for supply voltage.
Byte 88 is MSB. Byte 89 is LSB.

Laser bias current: Current, I, is given by
I = ISLOPE * IAD + IOFFSET
Where IAD is 16-bit unsigned A/D value at bytes 100-101, ISLOPE is unsigned fixed-point
value at bytes 76-77 and IOFFSET is signed 2's complement value with LSB equal to 2 µA at
bytes 78-79. The result, I, is 16-bit unsigned value with LSB equal to 2 µA.
Laser output power: Power, TP, is given by
TP = TPSLOPE * TPAD + TPOFFSET
Where TPAD is 16-bit unsigned A/D value at bytes 102-103, TPSLOPE is unsigned fixed-point
value at bytes 80-81 and TPOFFSET is signed 2's complement value with LSB equal to 0.1 µW at
bytes 82-83. The result, TP, is 16-bit unsigned value with LSB equal to 0.1 µW.
Received power: Power, RP, is given by
RP = RP4 * RPAD
4 + RP3 * RPAD
3+ RP2 * RPAD
2 + RP1 * RPAD + RP0
Where RPAD is 16-bit unsigned A/D value at bytes 104-105 and RP4, RP3, RP2, RP1 and RP0
are single precision floating-point values at bytes 56-75. The result, RP, is 16-bit unsigned
value with LSB equal to 0.1 µW.
