The Gennum® GN7355 is a 2nd generation 10G EPON Transceiver chip designed specifically for the ONU (Optical Network Unit). The GN7355 builds on the 1st generation platform (GN7350) and includes performance enhancements and new features that are designed to lower the both overall power and cost of the module.
Through re-timing the high speed signal, the CDR within the GN7355 ensures highest link margin and lowest jitter signal. This provides much needed margin on the IEEE P802.3av 10G EPON standard, simplifies the module design, and enables interoperability with different MAC (Media Access Control) vendors. Gennum's long-standing leadership in CDR technology allows for easy integration of this functionality into the chip, while still meeting the cost structure and low power consumption that PON systems demand.
