PRODUCT OVERVIEW
The SPLC-20-9D-2-B optical Video Small Form Factor
Pluggable (V_SFP) transceivers are high performance
integrated duplex data links for bi-directional
communication over single mode optical fiber. These
transceivers are designed to transmit/receive data rates
from 143Mbps to 1.485Gbps and are compatible with the
following standards:
SMPTE 292M (HDTV -- 1.485Gbps)
SMPTE 297M/259M (SDTV -- 143/177/270/360Mbps)
The Stratos Lightwave V_SFP transceiver is hot pluggable
which allows a suitably designed enclosure to be changed
from one type of external interface to another simply by
plugging in a V_SFP having the alternative external
interface. The SPLC-20-9D-2-B operates using a single
3.3V supply.
This optoelectronic transceiver module is a Class 1 Laser
product compliant with FDA Radiation Performance
Standards, 21 CFR Subchapter J. This component is also
Class 1 Laser compliant according to International Safety
Standard IEC-825-1.
LONG WAVELENGTH LASER
The SPLC-20-9D-2-B transmitter is provided with 1310nm
FP laser with angle polished fiber stub.
LONG WAVELENGTH RECEIVER
The SPLC-20-9D-2-B receiver is provided with long wave-
length (1270 - 1620nm) PIN pre-amp with angle polished
fiber stub.

NOTES:
(4) ± RX_2: Floating; Not internally connected
(5) ± TX_2: Floating; Not internally connected
(6) TX2_DIS: Floating; Not Internally Connected.
(7) ± RX_1: These are the differential receiver CML level outputs. They are AC coupled 100ohm differential lines which
should be terminated with 100ohm (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 400 and 1200mV differential (200-
600mV single ended) when properly terminated. Refer to figure 2 for recommended receive data lines terminations.
(8) Vcc: are the receiver and transmitter power supplies. They are defined as 3.3V±5% at the V_SFP connector pin.
Maximum supply current is 300mA. Recommended host board power supply filtering is shown in figure 5. When the
recommended supply filtering network is used, hot plugging of the V_SFP module will result in an inrush current of no
more than 30mA greater than the steady state value.
(9) ± TX_1: are the differential transmitter inputs. They are AC coupled differential lines with 100ohm differential termi-
nation 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 swing of 300 - 1860 mV differential (150-930mV single ended).
(10) TX1_DIS: is an input that is used to shut down the transmitter optical output when laser fault condition (internally
latched) occurs. . It is internally pulled up with a 4.7K - 10K ohm resistor. The states are:
Low (0 - 0.8V):
(>0.8, <2.0V):
High (2.0 - 3.465V):

Table D.2d: Example of floating point representation
This portion of the memory map contains real-time measurements of V_SFP transceiver temperature, laser bias
current, transmitted optical power, received optical power and transceiver supply voltage. The real-time diagnostics
registers are shown in table D.3 below.
The V_SFP transceivers are externally calibrated which means that the measurements are raw A/D values and must be
converted to real world units using calibration constants stored in EEPROM locations 56 – 95 at 2 wire serial bus
address A3h (Table D.2). The conversion process is described on following page. The alarm threshold values should
be interpreted in the same manner as real-time 16 bit data (i.e. They must be processed using the calibration
constants before they can be evaluated).

Digital state of the TX_DISABLE Input Pin. Updated within 100msec of
change of pin.
6 Soft TX Disable
110
Read/write bit that allows software disable of laser. Writing ‘1’ disables laser.
Turn on/off time is 100 msec max from acknowledgement of serial byte
transmission. This bit is “OR”d with the hard TX_DISABLE pin value.
Note,TX_DISABLE pin is default enabled unless pulled low by hardware. If
Soft TX Disable is not implemented, the transceiver ignores the value of this
bit. Default power up value is 0.
5-1 Reserved
0 Data_Ready_Bar
Res erved
Indicates transceiver has achieved power up and data is ready. Bit remains
high until data is ready to be ready at which time the device is sets the bit low.
