ML6652
10/100Mbps Ethernet Fiber and Copper
Media Converter with Auto-Negotiation
GENERAL DESCRIPTION
The ML6652 is a low cost multi-function / multi-standard
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. Support of other wavelengths is
possible using the PECL/LVPECL interface.
