Gigabit Ethernet SFP Multimode Transceiver with Digital Diagnostics TRPAG1SXLAES Product Description The TRPAG1SXLAES SFP ber optic transceiver with integrated digital diagnostics monitoring functionality provides a quick and reliable interface for Gigabit Ethernet1000BASE-SX multimode applications. The diagnostic functions, alarm and warning features as described in the Multi-Source Agreement (MSA) document, SFF-8472(Rev. 9.4), are provided via an I2C serial interface. A highly reliable 850nm wavelength Vertical Cavity Surface Emitting Laser (VCSEL) is used in the transmitter. The transceiver satises Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-60825 standards. The TRPAG1SXLAES transceiver connects to a standard 20-pad SFP connector for hot plug capability. This allows the system designer to make conguration changes or maintenance by simply plugging in dierent types of transceivers without removing the power supply from the host system. The transceiver has bail-type latch, which oers an easy and convenient way to release the module. The latch is compliant with the SFP MSA. The transmitter and receiver DATA interfaces are AC coupled internally. LV-TTL Transmitter Disable controlinput and Loss of Signal output interfaces are also provided. The transceiver operates from a single +3.3V power supply over an operating case temperature range of -40°C to+85°C. The housing is made of plastic and metal for EMI immunity.

The high speed DATA interface is differential AC-coupled internally with 0.1μF 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 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 SFP that are not write protected, and the negative edge clocks data from the SFP. The serial data signal (SDA) is for serial data transfer. The host uses SDA in conjunction with SCL to mark the startand end of serial protocol activation. The supported monitoring functions are internal temperature, supply voltage, bias current, transmitter power, average receiver signal, all alarms and warnings and software monitoring of TX Fault/LOS. The device is internally calibrated. Loss of Signal (LOS): The Loss of Signal circuit monitors the level of the incoming optical signal and generates a logic HIGH when an insufficient photocurrent is produced. 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 that should be pulled up with a 4.7 - 10kΩ resistor on the host board. TX Fault is latched per SFP MSA. The data transfer protocol and the details of the mandatory and vendor specific data structures are defined in the SFPMSA, and SFF-8472, Rev. 9.4 TX_Disable: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled (less than -45dBm). Power supply and grounding: The power supply line shouldbe well-filtered. All 0.1μF power supply bypass capacitors should be as close to the transceiver module as possible. Serial Identification and Monitoring: The module definition of SFP is indicated by the three module definition pins, MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2). Upon power up, MOD_DEF(1:2) appear as NC (no connection), and MOD_DEF(0) is TTL LOW.
