Our  evaluation board for the 10.3125-Gbps SFP+ LR reference design was designed to show the optical performance of the ONET1151L laser driver, the ONET8551T high-gain transimpedance amplifier (TIA) and the ONET1151P limiting amplifier.

The ONET1151L is used to drive a 1310-nm DFB laser in an LC transmit optical sub-assembly (TOSA). The ONET1151P is used to amplify the signal from the PIN-TIA LC receive optical sub-assembly (ROSA) which contains the ONET8551T TIA. An MSP430FR5728 microcontroller (MCU) is used to control the setup of the ONET1151L and ONET1151P in conjunction with a graphical user interface (GUI). The MSP430™ MCU also stores the register settings in FRAM. The TPS82693 high-efficiency MicroSiP step-down converter is used to supply 2.85 V to the ICs to decrease the module power dissipation.

This design is a functional SFP+ module used to show the performance of the transmitter and receiver. Digital diagnostics and temperature compensation of the laser driver modulation current are not included.

  • Enables <1-W 10GBASE-LR SFP+ transceiver
    • Decreased component power consumption (<1 W)
    • Low power supply voltage (2.85 V)
    • High mask margin for both receiver and transmitter
  • Decreases customer evaluation time
    • Includes SFP+ host board and user-friendly GUI
