DM9162: 10/100 Mbit Fast Ethernet Physical Layer TX/FX
DAVICOM’s DM9162/DM9162I is a industrial- temperature physical layer, low power, and single-chip 10BASE-T/100BASE-TX transceiver specifically designed for consumer electronics, industrial, and enterprise applications. Through using a CMOS process, the DM9162 has the advantage of ensuring both high performance and savings in power consumption. Through utilization of automatic media speed and protocol selection, the auto-negotiation function is
strongly supported in the DM9162. Then due to the built-in wave shaping filter, the DM9162 has a significant convenience of not requiring an external filter to transport signals to the media in 10BASE-T or 100BASE-TX during Ethernet operation.

DM9162 Features
The DM9162 is the replacement for DM9161C. In the LQFP-48 package it is backward compatible to DM9161A and DM9161C.
Its main advantages are:
- 50MHz clock out at RMII applications which can save BOM cost and design efforts at the system designer
- cost effective 0,162µ process
- QFN-32 & LQFP-48 packages
- 10/100Base-TX + 100FX
- Current consumption 90mA + 40mA (transformer)
- 50MHz RMII clock output
- Auto MDI-X
- 0.162 µm Process
- LED Status (Link/Activity, Speed, Full Duplex/Collision)
- Full-Duplex or Half-Duplex
- Compatible to IEEE802.3u
- MII and Reverse MII
- SPI EEPROM Interface
- Integrated 3.3V to 1.8V regulator
- Temperature Range: 0°C to 70°C and -40° to 85°C
As we know, the trend of CPU/processor is toward small package and low pin count in which RMII interface will be applied. Besides 48-pin LQFP in DM9162 package, 32-pin QFN or 24-pin QFN (RMII only) is available.
It contains the entire physical layer functions of 100BASE-TX as defined by IEEE802.3u:
- Physical Coding Sublayer (PCS)
- Physical Medium Attachement (PMA)
- Twisted Pair Physical Medium Dependent Sublayer (TP-PMD)
- 10Base-TX Encoder/Decoder (ENC/DEC)
- Twisted Pair Media Access Unit (TPMAU)
Furthermore, due to the built-in wave shaping filter, the DM9162 needs no external filter to transport signals to the media in 100BASE-TX or 10BASE-T Ethernet operation.
