Multi-rate 10-Gigabit SR-1XFP Transceiver with Digital Diagnostics TXP1XGDS1x Pb Product Description The TXP1XGDS1x XFP multi-rate fiber optic transceivers with digital diagnostics monitoring functionality provide a quick and reliable interface for 10G short reach applications. The diagnostic functions, alarm and warning features as described in the XFP Multi-Source Agreement (MSA) are provided via standard I2C serial interface. The transceivers are compliant with the XFP Multi-Source Agreement and are designed to support SONET/ SDH, 10G Ethernet, and 10G Fiber Channel data rates from 9.95Gb/s to 11.09Gb/s. Each transceiver utilizes a 1310nm Distributed Feed Back (DFB) laser for up to 10km data transmission over single mode fiber. They satisfy Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-60825 standards. The receiver features an InGaAs/InP PIN photodiode and a transimpedance amplifier IC optimized for high sensitivity and wide dynamic range. The transmitter and receiver DATA interfaces are AC-coupled Current Mode Logic (CML). LV-TTL Transmitter Disable control input and Loss of Signal output interfaces are also provided. The transceivers connect to standard 30-pad XFP connectors for hot plug capability. This allows the system designer to make configuration changes or maintenance by simply plugging in different types of transceivers without removing the power supply from the host system. The transceivers operate from a single +3.3V power supply over a operating temperature range of -5°C to +70°C (Commercial), -5°C to +85°C (Extended), or -40°C to +85°C (Industrial).

The Mod_NR output pin is an open collector and must be pulled to Host_Vcc on the host board. RX_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. Module Behavior During P_Down and RST: During execution of a reset (t_init) or while held in Power Down mode, a module may be unable to determine the correct value for Mod_NR and RX_LOS. These outputs as well as all interrupt related flags, except completion of Reset flag, shall be disregarded by the host. When the module completes a Reset and is not in Power Down mode, the module must represent the correct value of both signals on its outputs before posting a completion of reset interrupt to the host. P_Down/RST: The negative edge of Reset Function signal initiates a complete module reset. TX_Dis: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled. (less than -45dBm). P_Down: The Power Down Function pin, when held High by the host, places the module in the standby (Low Power) mode with a maximum power dissipation of 1.5W. This protects hosts which are not capable of cooling higher power modules which may be accidentally inserted. The module’s 2-wire serial interface and all laser safety functions must be fully functional in this low power mode. During P_Down, the module shall still support the completion of reset Interrupt, as well as maintain functionality of the variable power supply. At no time shall a module cause spurious assertion of the Interrupt pin. When a host initially applies power to a module with the P_Down/RST signal asserted, a module comes up in power down mode. The module shall only assert the Interrupt signal pin to inform the host it has completed a reset. The completion of reset flag shall be the only interrupt source flag set during power down mode. The host is expected to clear this interrupt before releasing the module from the power down mode. The transition from power down mode to normal mode will trigger a reset of the module and result in a 2nd module reset and a 2nd reset completion interrupt to the host. Mod_NR: The Mod_NR is an output pin that when High, indicates that the module has detected a condition that renders transmitter and or receiver data invalid, shall consist of logical OR of the following signals: • Transmit Signal Conditioner Loss of Lock • Transmitter Laser Fault Power Supply and Grounding: The power supply line should be well-filtered. All 0.1μF power supply bypass capacitors should be as close to the transceiver module as possible. • Receiver Signal Conditioner Loss of Lock Other conditions deemed valuable to the detection of fault may Oplink Communications, Inc 5 S0268.
