Fast Ethernet media converter

26 September 2001 Telecoms, Datacoms, Wireless, IoT

Micro Linear's ML6651 is a Media Converter that provides 10 Mbps and 100 Mbps signal conversion between twisted pair and fibre-optic Ethernet technologies. The device supports conversion between: 10Base-T and 10Base-FL; 100Base-TX and 100Base-FX/SX; 100Base-Fx and 100Base-SX; FLP Bursts and FLNP Bursts.

The device supports 10 Mbps and 100 Mbps operating data rates with Auto Negotiation for SPEED and DUPLEX mode setup using 850 nm or 1350 nm optics. One or both of the fibre-optic and twisted-pair interfaces can be interfaced to industry standard fibre-optic PMD modules using PECL/LVPECL compatible modes.

Key features are:

* Complete implementation of fibre-optic and twisted pair media interface.

* Intended to support ISO/IEC 8802.3, IEEE 802.3 and TIA/EIA-785, including full auto-negotiation for twisted pair and fibre-optic media.

* 850 nm, 1300 nm miniature fibre-optic components and PMD modules.

* Supports 1:1 receiver/transmitter transformer ratio for twisted pair.

* Low latency 10 Mbps path.

* Integrated voltage and current references.

* Integrated twisted pair output wave shaping eliminate external filtering.

* Integrated twisted pair 10Base-T input filter and 100Base-TX equaliser with baseline wander correction circuit.
