description: |
The DAP8211R(I) is a Gigabit Ethernet PHY with RGMII interface,
supporting IEEE 802.3az Energy Efficient Ethernet, IEEE 1588 SyncE,
and an internal packet generator for diagnostics.
Specifications:
- 10BASE-Te, 100BASE-TX, 1000BASE-T
- RGMII with configurable TX/RX clock delays (150 ps steps, 0-2250 ps)
- IEEE 802.3az-2010 Energy Efficient Ethernet
- IEEE 1588 SyncE support
- Internal packet generator and checker for link diagnostics
