DM9161AEP 10/100 Mbps Fast EthernetPhysical Layer Single Chip Transceiver

General Description

The DM9161A is a physical layer, single-chip, and low power transceiver for 100BASE-TX and 10BASE-T

operations. On the media side, it provides a direct interface either to Unshielded Twisted Pair Category 5 Cable

(UTP5) for 100BASE-TX Fast Ethernet, or UTP5/UTP3 Cable for 10BASE-T Ethernet. Through the Media

Independent Interface (MII), the DM9161A connects to the Medium Access Control (MAC) layer, ensuring a high

inter operability from different vendors.

TheDM9161A uses a low power and high performance advanced CMOS process. It contains the entire physical

layer functions of 100BASE-TX as defined by IEEE802.3u, including the Physical Coding Sublayer (PCS),

Physical Medium Attachment (PMA), Twisted Pair Physical Medium Dependent Sublayer (TP-PMD), 10BASE-TX

Encoder/Decoder (ENC/DEC), and Twisted Pair Media Access Unit (TPMAU). The DM9161A provides a strong

support for the auto-negotiation function, utilizing automatic media speed and protocol selection. Furthermore, due

to the built-in wave shaping filter, the DM9161A needs no external filter to transport signals to the media in

100BASE-TX or 10BASE-T Ethernet operation.

Koben Electronics was founded in 1995 and is located in the Silicon Valley of China, Shenzhen. 

The mission of Koben has always been to provide quality electronics components to manufacturers worldwide. Early on we became a primary conduit for end-of-program and overstock inventory for major distributors such as Future Electronics and contract manufacturers as Flextronics. Koben has since then added sourcing of high quality components from local manufacturers in China.

Koben has always been customer driven rather than opportunity driven. Meaning- we will always choose path that is best for long term relationship with customer over short term view. It is why we have one of the highest customer retention scores of China based distributors.
