Current 40G transponders are designed using components in large and expensive metal packages with microwave connectors. In order to enable widespread deployment of 40G and 100G technologies, the industry needs to develop solutions based upon surface mount technology to reduce transponder size and cost while not compromising signal integrity.
“Inphi is driving the ecosystems to transition from metal packages with microwave connectors to surface mount solutions,” said Loi Nguyen, vice president of technology, Inphi. “Inphi is working closely with industry leaders to develop the next-generation of compact, lower-cost surface mount 40G and 100G components. The 2811DZ underscores our leadership in driving next generation solutions for 40G/100G telecom infrastructure applications.”
Unlike other competing single-ended solutions, Inphi’s 2811DZ’s differential architecture results in the largest output swing, 9 Vpp typical, necessary to drive all 40G DQPSK modulators in the market. In addition, the 2811DZ’s differential design is suitable for interfacing with other components on a PC board without incurring significant losses and excessive jitter. A reference design on PC board is available to assist customers with the design of high speed differential transmission lines.
