DNC3X3825 产品详情

Description
The DNC3X3825 is a twisted-pair transceiver macrocell that supports transmission and reception over category 3 unshielded twisted-pair (UTP) cable and category 5 UTP.
The DNC3X3825 has been designed specifically for applications that support both 10Base-T and 100Base-X, such as network interface cards (NICs), switches.

Features
General
■ Ports individually configurable
■ Autonegotiation and management:
    — Fast link pulse (FLP) burst generator.
    — Arbitration function.
    — Accepts preamble suppression.
    — Operates up to 12.5 MHz.
■ Supports the MII station management protocol and frame format (clause 22): basic and extended register set.
■ Supports next page.
■ Provides status signals: receive activity, transmit activity, full duplex, collision/jabber, link integrity, and speed indication.
■ Powerdown mode for 10 Mbits/s and 100 Mbits/s operation.
■ Loopback testing for 10 Mbits/s and 100 Mbits/s operation.
■ 0.25 µm low-power CMOS technology.
■ Single 3.3 V power supply operation.
■ 25 MHz XTAL oscillator input or 25 MHz/50 MHz/ 125 MHz clock input.
■ Compatible with RMII (standard version) and SMII (standard version).

Octal 10 Mbits/s Transceiver
■ DSP based.
■ Compatible with IEEE * 802.3 10Base-T standard for twisted-pair cable.
■ Half- and full-duplex operations.
■ Autopolarity detection and correction.
■ Adjustable squelch level for extended wire-length capability (two levels).
■ Interfaces with IEEE 802.3u media independent interface (MII) or a serial 10 Mbits/s 7-pin interface.
■ On-chip filtering eliminates the need for external filters.

Octal 100 Mbits/s Transceiver
■ Compatible with IEEE 802.3u MII (clause 22), PCS/PMA (clause 24), PMD (clause 25), MII management, and autonegotiation (clause 28) specifications.
■ Selectable 5-bit code-group (PDT/PDR interface) or 4-bit data nibbles (MII interface) input/output.
■ Full- or half-duplex operations.
■ Optional carrier integrity monitor (CIM).
■ Selectable carrier sense signal generation (MCRS) asserted during either transmission or reception in half duplex (MCRS asserted during reception only in full duplex).
■ Adaptive equalization and baseline wander correction.
■ On-chip filtering eliminates the need for external filters.

Octal 100 Mbits/s FX Transceiver
■ Compatible with IEEE 802.3u 100Base-FX standard.
■ Reuses existing twisted-pair I/O pins for compatible fiber-optic transceiver pseudo-ECL (PECL) data.
■ Fiber mode automatically configures port:
    — FX mode enable is pin or register selectable
    — Disables autonegotiation and 10Base-T.
    — Enables 100Base-FX remote fault signaling.
    — Disables MLT-3 encoder/decoder.
    — Disables scrambler/descrambler.

关于 Agere Systems


Agere Systems was a semiconductor company that specialized in providing integrated circuits (ICs) for telecommunications and storage applications. The company was founded in 2000 as a spin-off from Lucent Technologies, and was headquartered in Allentown, Pennsylvania, USA.

Agere Systems' product portfolio included ICs for wireless communication, networking, and storage applications. These products were used in a wide range of devices, including mobile phones, routers, switches, and data storage devices.

Agere Systems was known for its innovation and expertise in advanced semiconductor technologies, such as copper-based interconnects and silicon germanium (SiGe) technology. The company also had a strong focus on research and development, and held numerous patents in semiconductor design and manufacturing.

In 2005, Agere Systems was acquired by LSI Corporation, which later became part of Avago Technologies. Today, the technology and products developed by Agere Systems continue to be used in a variety of telecommunications and storage applications.
