MDC/MDIO interface specification in 802.3 IEEE 802.3 NGAUTO SG — Ad-hoc meeting, April 19, 2017 P O F Knowledge Development Current specifications per 802.3 (I) •Legacy MDIO interface speed is limited to 2.5 MHz (the minimum high and low times for MDC are 160 ns each, and the minimum period for MDC is 400 ns, per subclause 22.2.2.13). Furthermore, there is an FD D-sub connector for MDIO on the front panel of the XENPAK Load Module (shown in Figure A-9 on page A-9). Both the MDIO and power are available through pins on the adapter and serve the same function as the D-sub connector on the XAUI Load Module. The adapter is shown in Figure A-8. Figure A-8. Fujitsu to XENPAK Adapter. 2001. 12. 2. · The IEEE RFC802.3 specification defines MDIO in Chapter 22, and Chapter 45 further defines the 802.3ae specification. This article discusses both. Rev 1.9 - Added 0Bh to the Extended Specification Compliance Codes Rev 2.0 - Changed SFP Common Management Spec to SFF-8472 - Deleted 802.3bj from 28 Gb/s CXP Rev 2.1 - Aligned CXP and HD naming w/QSFP nomenclature Rev 2.2 - Replaced duplicated codes 08-0Ah in the Extended Specification Compliance Codes.

This port is referred to as the 'cpu' port. And there is a management plane via MDIO, or SPI, I2C, MMIO. The AG-HPD24 is a portable P2 deck that meets the HD recording needs of high-end users in broadcasting and movie production. It supports 1080/24p native recording of 1080/24PsF input and variable frame rate recording as well as multi-format HD recording. It's also equipped with a 3D sync function that enables 3D recording with a high-quality.
