Micrel slashes BOM costs with new 2.5Gbps laser diode driver featuring APC and power monitoring

(Product News, 11 Jun 2008 )

Micrel has launched a new stand-alone 2.5Gbps laser diode driver (LDD) with integrated Automatic Power Control (APC) and a power monitoring feature to keep 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. The device is also well suited for SFF and SFP modules. The IC is currently available in volume and pricing starts at $3.00 for 1K quantity. Samples can now be ordered on line on Micrel’s web site at: http://www.micrel.com/ProductList.do.

The driver can deliver modulation current up to 85mA and bias current up to 70mA, and is suitable for both AC and DC-coupled laser interfaces due to its high compliance voltage. The SY88212L also features an APC fault indicator, TXenable/TXdisable for enabling/disabling the driver, 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.
