Gennum debuts 10-Gbit/sec laser drivers for optical transceivers
JANUARY 9, 2007 -- The GN1152B direct modulated laser driver and GN1152D externally modulated laser driver products offer enhanced performance and signal integrity features, say company representatives.
JANUARY 9, 2007 -- Gennum Corp. has announced availability of its new 10-Gbit/sec laser and EA driver products for optical transceivers.
The GN1152B direct modulated laser driver and GN1152D externally modulated laser driver products offer enhanced performance and signal integrity features, say company representatives. Both devices are available in RoHS-compliant 4- x 4-mm, 24-pin QFN packages for ease of implementation in current and next-generation transceiver form factors.
The devices are suitable for use in 10-Gigabit Ethernet, 10G Fiber Channel, SONET OC-192, SDH STM-64, and emerging 10-Gbit/sec FTTH applications.
"We have shipped over 1 million 10-Gbit/sec transceiver ICs in the last two years and therefore have a detailed understanding of what results in good performance in customer modules," contends Imran Sherazi, manager of marketing and applications in Gennum's Data Communication Products Division. "The new laser driver products build upon the success of our previous 10-Gbit/sec ICs and offer jitter reduction features not seen before in such products."
"Our second-generation CDR products introduced techniques to minimize jitter generation in telecom modules; however, laser drivers remain a significant source of jitter generation," adds Ryan Latchman, senior product manager, Data Communications Product Division. "Therefore, we have employed techniques used in our CDR products to enable a significant reduction in system level jitter generation through the use of our new laser driver devices. These new laser driver products round out our product portfolio for 10-Gbit/sec transceiver modules," he says, "and, together with our industry-leading CDR and TIA products, provide our customers with a complete chipset for XFP and SFP+ applications."
Samples of the GN1152B and GN1152D devices are available now. The devices are priced under $10 in production volumes.
