OVERVIEW
Gennum has broken away from the traditional approach to ROSA design and created a line of ROSA
products that delivers the best performance in the industry. Gennum’s ROSAs o er:
•
Best-in-class stressed receiver sensitivity
•
High gain to ensure exceptional crosstalk performance within the module
•
Patented Rchip technology to ensure maximum module manufacturing yield
•
Successful interoperability of the Gennum LRM ROSA with all leading EDC solutions for SFP+ modules
RCHIP TECHNOLOGY: REVOLUTIONIZING THE ROSA FROM THE INSIDE OUT
Traditional ROSA architecture, which typically include four or ve discrete components, is vulnerable to
wide performance variations across a number of parameters. is negatively impacts the manufacturing
yield of the transceiver module. Building on its innovative technology practices, Gennum has leveraged its
world-class Transimpedance Ampli er (TIA) design expertise and wafer scale processing to develop the
Rchip, a die stack implementation of an optical receiver.
With the new Rchip architecture, Gennum is able to optimize the complete receiver at the silicon level. e
result is a ROSA with exceptional performance that is insensitive to assembly variability and is guaranteed
by design. e consistent high performance of each Gennum ROSA allows module manufacturers to enjoy
larger performance margins in their designs and thus, bene t from maximal manufacturing yields.
