Davicom´s single-port PHY series are low power Physical Layer Transceiver in LQFP-48 and QFN-32/24 packages. They are fully compliant to IEEE 802.3, IEEE 802.3u 10Base-T / 100Base-TX / 1000Base-T and ANSI X3T12 TP-PMD 1995 standards. The front-end can drive 10Base-T, 100Base-TX TP-transformer and FX-transceiver. Available Interfaces for connection to MAC layer chips, switches or microcontrollers with integrated MAC are MII, RMII and SNI/GPSIAn integrated wave filter saves external filters for the signal forwarding in 100Base-TX or 10Base-T modes. DM9162, DM9163 and DM9119 can internally generate the 50MHz reference clock or alternatively use use the external 50MHz system clock. DM9163 additionally offers 8kV Isolation Voltage and 3.3V transformer central tap as well as a BIST (Built-in-self-test) function.
DM9119 is very cost effective PHY due to the 0,11µ manufacturing process. It also has a very low current consumption because the signals are transferred by voltage instead of current. Additional power saving modes were added.
