CYBERJAYA, Malaysia -- The SRL3101NS launched earlier this year has been tested and evaluation boards are available for sampling. The integrated PMD chip, a world’s first, functions at 3.125 Gbits/sec per channel, is targeted at very short reach (VSR) applications. Separate versions of the transmitter (Tx) and Receiver (Rx), also at the same speed, are also available.

“There is a list of customers both in the US, Europe and Asia Pacific waiting for the samples. The 3.125Gbps integrated optical PMD chip is of course the star of the show. The media and customer response for the chip at the OFC was overwhelming and we are happy to announce that the samples are now available,” said Sean Murphy, Chief Executive Officer.

At the OFC this year, SiRES LABS launched the SRL3101NS a 3.125Gbps integrated optical PMD, a world’s first that proved exciting to optical module makers looking for smaller die size and better performance optical solutions.

The optical PMD (transceiver) chip integrates the transimpedance amplifier (TIA), limiting amplifier (LA), VCSEL driver, and LVDS interface typically available as individual components. The SRL3101NS features both digital and analog control and monitoring functions and comes in a die measuring 1.6x2.2 mm.

Optimized for speeds ranging from 1 to 3.125 Gbits/sec and consuming 250 mW of power under maximum operating conditions for both transmitter and receiver functions, the SRL3101NS is designed for use with VCSELs and PIN/APDs in VSR applications such as Gigabit Ethernet, SONET VSR links, intra-system, backplanes, SAN, Fibre Channel, terabit routers and switches.

The SRL3101NS is available packaged or as bare die with large bond pad pitches. Using the CMOS process, the chip has been designed using the company's dynamic self adaptive biasing (dSAB) technology that compensates for process- and temperature-induced parametric variations and allows for a higher yield of analog circuits in CMOS.
