SMI (MDIO) Exerciser and Protocol Analyzer
The PGY-SMI-EX-PD SMI Protocol Analyzer provides comprehensive functions for capturing and debugging communication between host and DUT. The PGY-SMI-EX-PD can be configured as master or slave, generate SMI traffic and decode SMI packets. SMI, also referred to as Management Data Input/Output or MDIO, is a 2-wire serial bus used to manage physical layer devices in Media Access Controllers (MACs) in Gigabit Ethernet devices. The management of these PHYs is based on accessing and modifying their various registers.
PGY-SMI-EX-PD is the leading instrument that enables the design and test engineerstotest the SMI designs for its specifications by configuring PGY-SMI -EX-PDasmaster/slave, generating SMI traffic with error injection capability anddecodingSMIProtocol packets.
