Semtech GN1153B/C

11.3 Gbps DFB/FP Laser Driver

Add to Watch List

The GN1153B and GN1153C are low power 11.3 Gbps laser and modulator drivers for optical fiber transceiver applications.

They are suitable to drive Fabry-Perot (FP) and Distributed Feedback (DFB) laser diodes. Both devices offer identical functionality, though the GN1153C is optimized to deliver improved performance at the high bit rates.

Both devices use a single 3.3V supply (optional 5V output stage). The inputs are designed to be AC-coupled, and have internal 100 ohms differential terminations. The output is internally terminated with 25 ohms. External pull-up inductors may be used on the outputs to provide adequate head room, to allow large signal swings from a 3.3V supply.

The devices have control inputs for laser output power, extinction ratio (ER) and output crossing point adjustments. Additional control pins are available to further optimize the output eye.

Features


  • Low power laser driveer designed to meet the power requirements of SFP+
