Single PHY Transceivers


Davicom´s single-port PHY series are low power Physical Layer Transceiver in LQFP-48 and QFN-32 packages. They are fully compliant to IEEE 802.3, IEEE 802.3u 10Base-T / 100 Base-TX 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.

DM9161 and DM9161A are based on a power saving analog manufacturing process. DM9161B, DM9161C, DM9162 and DM9163 are more cost-effective due to a digital signal process. All chips except DM9161 support HP´s Auto MDI-X feature.

DM9162 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.
