2.5Gbps laser diode driver

Advance control features paired with power monitoring

Micrel has launched a new stand-alone 2.5Gbps laser diode driver (LDD) with integrated Automatic Power Control (APC) and a power monitoring feature, which maintains average optical power constant during temperature changes and over the lifetime of the laser. The SY88212L is also designed with high compliance voltage, allowing it to be DC-coupled to the laser to reduce external component count and power consumption. The SY88212L is a single-supply, 3.3V laser driver designed for datacom and telecom applications, including LAN and MAN with any data rates up to 2.5Gbps. Such applications include FC, GbE, SONET, OC3/12/24/48 and SDH, STM 1/4/8, and extend to SFF and SFP modules. Additional features include TXenable/TXdisable and a power-monitoring pin, which monitors the current that is proportional to the sum of bias current and half of modulation current. It is available in a 24-pin (4mm x 4mm) MLF package.
