Application Notes
Electrical Interface: Signal interfaces are compatible with
the SFP MSA specification. The high speed DATA interface
is differential AC-coupled internally and can be directly
connected to a 3.3V SERDES IC. All low speed control and sense
output signals are open collector TTL compatible and should
be pulled up with a 4.7 - 10kΩ resistor on the host board.
TX_Fault: The output indicates LOW when the transmitter
is operating normally and HIGH with a laser fault including
laser end-of-life. TX Fault is an open collector/drain output and
should be pulled up with a 4.7 - 10kΩ resistor on the host board.
TX_Disable: When the TX Disable pin is at logic HIGH,
the transmitter optical output is disabled. The laser is also
disabled if this line is left floating, as it is pulled high inside
the transceiver.
Serial Identification and Monitoring: The module definition
of SFP is indicated by the MOD_ABS pin and the 2-wrie serial
interface. Upon power up, the 2-wrie interface appears as NC
(no connection), and MOD_ABS is TTL LOW. When the host
system detects this condition, it activates the serial protocol
(standard two-wire I²C serial interface) and generates the
serial clock signal (SCL). The positive edge clocks data into the
EEPROM segments of the device that are not write protected,
and the negative edge clocks data from the device. The serial
data signal (SDA) is for serial data transfer. The host uses SDA
in conjunction with SCL to mark the start and end of serial
protocol activation. The supported monitoring functions
are temperature, voltage, bias current, transmitter power, all
alarms and warnings, and software monitoring of TX Fault. The
device is internally calibrated.
The data transfer protocol and the details of the mandatory
and vendor specific data structures are defined in the SFP MSA,
and SFF-8472, Rev. 9.4.
Power Supply and Grounding: The power supply line should
be well-filtered. All power supply bypass capacitors should be
as close to the transceiver module as possible.
