A 2.7Gbps high-current, low power laser driver for FP/DFB lasers was recently unveiled by Micrel Inc. The SY88982 offers 2.4V minimum laser compliance voltage for high-current, DC-coupled applications for Metro Area Networking (MAN), Local Area Networking (LAN) and Storage Area Networking (SAN) telecom and datacom markets.

"In today's SFF and SFP modules markets, DC-coupled operation and board space are the two most important requirements," said Thomas Wong, VP of high bandwidth products at Micrel. "The SY88982 is the smallest laser driver with the most compliance voltage."

The SY88982 is a 3.3V, 2.7Gbps chip offering 2.4V minimum voltage and a high modulation current up to 90mA. It is available in the small form factor, 16-pin, 3-by-3mm MLF Pb-free packaging. Designed for multi-rate LAN and MAN applications such as FC, GbE, SONET OC-3/12/24/24 and SDH/STM1/4/8/16, this IC requires fewer components because of DC-coupling capability and consumes less power due to the lower supply current.

Wong added, "Using the SY88982 together with our [Micrel's] MIC3001 optical transceiver management IC allows for modulation and bias current control and monitoring, automatic power control and temperature compensation, providing designers with the most competitive FP/DFB laser driver solution available on the market."

The new SY88982 chip is available in volume orders, with pricing starting at $5.50 for 1,000-unit orders.
