Laser Driver Offers Power Monitoring and Management
Keeping optical power constant during temperature changes and over the device’s lifetime, Micrel’s SY88212L laser diode driver includes automatic power control with fault indicator, TXenable/disable, and a power-monitoring pin. The 24-pin 4-mm2 MLF-packaged device can deliver modulation current up to 85 mA, bias current up to 70 mA, and is suitable for both AC- and DC-coupled laser interfaces. Suitable for small form-factor products and designs, the single-supply, 3.3-V laser driver targets datacom and telecom applications, including FC, GbE, SONET, OC3/12/24/48 and SDH, STM 1/4/8 with data rates up to 2.5 Gbit/s. Pricing starts at $3.00 for 1K quantity.
