CYBERJAYA, Malaysia -- SiRES LABS' 3.125Gbps VCSEL driver which consumes just 40mW of power is set to be one of the optical industry's lowest, saving as much as 40 percent over similar products. SiRES LABS a pioneer in PMD level component integration recently launched its single and quad channel VCSEL driver in speeds of 3.125, 2.5 and 1.25Gbps respectively for use in backplanes, intra system parallel links, OC-192 VSR SONET/SDH links, Fiber Channel, DVI Links and laser printers.

"With this very efficient power consumption feature, the need for heat sinks is eliminated or reduced bringing about substantial cost saving advantages," said CEO Sean Murphy. "Also, with lower heat dissipation on board, components can be more densely packed without compromising on performance levels," he adds.

Among the key advantages the VCSEL Drivers offer are the flexibility of selecting variable IBIAS and IMOD values programmable upper and lower threshold levels for VCSEL fault detection hence allowing the chip to be easily matched with third-party VCSELs. The added feature of integration of a temperature sensor enables the chip to be used in applications where temperature compensation is required without the need to use monitor photodiodes.

Other features include multi-standard differential inputs accepting LVDS, LVPECL and CML (standards) formats and compatibility to 850nm VCSELs. It has a modulation current of 12mA and a bias current of 11mA. The disable and enable times are 4ns and 17.7ns respectively and the transmitter ready (TXR) response time is 144ns. The components are available in bare die format.
