ML6652
10/100Mbps Ethernet Fiber and Copper
Media Converter with Auto Negotiation
GENERAL DESCRIPTION
FEATURES
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.
• 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 auto-
negotiation 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
