ML6652 10/100Mbps Ethernet Fiber and Copper Media Converter with Auto Negotiation
GENERAL DESCRIPTION
The ML6652 is a low cost/low LED current drive single chip Media Converter that provides 10Mbps and 100Mbps signal conversion between twisted pair and fiber 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 10Mbps and 100Mbps operating data rates with Auto Negotiation using 850nm or 1300nm optics. One or both of the fiber optic and twisted pair interfaces can be interfaced to industry standard miniature fiber optic components or Physical Media Dependent (PMD) modules using Positive Emitter Coupled Logic/Low Voltage Positive Emitter Coupled Logic (PECL/LVPECL) compatible modes. Other wavelengths possible via PECL/LVPECL interface.
FEATURES
· Complete implementation of fiber optic and twisted pair media interface · Intended to support ISO/IEC 8802.3, IEEE 802.3 and TIA/EIA-785 Industry Standards, including full autonegotiation for twisted pair and fiber optic media · 850nm, 1300nm miniature fiber optic components and PMD modules · Supports 1:1 receiver/transmitter transformer ratio for twisted pair · Low latency 10Mbps path · Integrated voltage and current references · Integrated twisted pair output wave shaping eliminates external filtering · Integrated twisted pair 10Base-T input filter and 100Base-TX equalizer with baseline wander correction circuit · Serial Management Interface · Full and Half Duplex with Auto-Negotiation · Integrated LED Driver · Integrated Data Quantizer · Small 44-Pin TQFP · Low 3.3V operation
APPLICATIONS
· Single/Multi Port 10/100 Auto Negotiating Media Converters · Single/Multi Port 100Base-FX/SX to 100Base-TX Media Converters · Single/Multi Mode Fiber Converters · Fiber Optic Front-End for Network Interface Cards (NICs), Repeaters, Bridges, Hubs, Switches, and Routers · Residential Connectivity and Gateway/Demarcation Products · Redundant Link Converters · Wavelength Converters
