The ML6652 Fast Ethernet Media Converter provides
signal conversion between the following standards:
•
•
•
•
The ML6652 supports conversion between Twisted Pair
Side, Fast Link Pulses (FLP) and Fiber Side, Fiber Link
Negotiation Pulses (FLNP). It supports ISO/IEC 8802.3,
IEEE 802.3, and TIA/EIA-785 including Auto-Negotiation
on both twisted pair and fiber optics.
The ML6652 data interfaces can all be configured in a
number of ways. The twisted pair inputs and outputs can
be configured in Twisted Pair Mode to interface with a 1:1
transformer for transmit and receive or in PECL/LVPECL
Mode to interface a PMD module. The fiber optic inputs
and outputs can be configured in Quantizer/Fiber Optic
Mode with an LED driver or in PECL/LVPECL Mode. LED
status outputs identify internal operational status.
The ML6652 operating modes are configurable through
control input pins (at power up) or through management
control registers that are programmable through an
interface protocol compatible with MII Serial
Management Interface as defined in IEEE 802.3-1998
standards.
