LAN8720A → DM9162
Cross-reference / replacement · Microchip (SMSC) → DAVICOM
- Type:
- 10/100 Ethernet PHY

- Single PHY
- MAC Interface:
- MII / RMII
- Standards:
- IEEE 802.3 / 802.3u
Compatibility & sourcing notes
The LAN8720A and DM9162 are both standard 10/100 Ethernet PHYs managed over MDIO/MDC (clause-22), so they interchange behind an RMII MAC. But the pinout/package and vendor extended registers differ — a re-layout and PHY driver/init change are required, so it is a design-in alternative. Use the RMII-capable (50MHz) DM9162, not the MII-only DM9161A.
A functional alternative requiring design-in: pinout and driver may differ — re-validate with the corresponding development resources before production.
