Low Speed Electrical Characteristics

MDIO Management Interface

The GAOTek CFP LR4 supports the MDIO interface specified in IEEE802.3 Clause 45. This 2-wire management data I/O interface is provided for the module status monitoring and control. The management data clock (MDC) provides clocking for the data that is passed on the MDIO port. Five further pins allow for loading of a port address (PORT_ADDR0-4) into the module. The CFP transceiver supports MDIO pages 8000h NVR 1 Based ID registers, 8080h NVR 2 Extended ID registers, 8100h NVR 3 network lane specific registers, and pages A000h CFP module VR 1 registers,A080h MLG VR 1 registers, A200h network lane VR 1 registers,A280h network lane VR 2 registers. Details of the protocol and interface are explicitly described in CFP MSA Management Interface Specification. Please refer to the specifications for design reference.
