10/100Mbps Fiber and Copper Ethernet

Media Converter User’s Guide

OVERVIEW

The ML6651 Evaluation Board demonstrates the
capabilities of the ML6651. The eval-board’s block diagram
is shown in Figure 1. This integrated circuit is a Media
Converter between twisted pair and fiber optic Ethernet
technologies. It supports conversion between 10BASE-T
and 10BASE-FL, between 100BASE-TX and 100BASE-FX/SX
and, between FLP Bursts and FLNP Bursts. (FLP: Fast Link
Pulse, FLNP: Fiber Link Negotiation Pulse.) One or both of
the fiber optic or twisted pair interfaces can be configured
to interface with industry standard 1x9 fiber optic PMD
modules, (using the PECL compatible modes) or minature
fiber optic comonents (typically called “sugar-cubes”) as it
supports both 850nm and 1300nm optics.

Three of the many possible configurations of the ML6651
eval boards are offered:

1) 10/100Mbs copper to 850/1300nm fiber optic “sugar
cubes”. This configuration has two board sizes: full
(rev. B), and mini (rev. E). See attached schematic
(Appendix D) labeled “ML6651 EVAL BOARD
SCHEMATIC (sugar cubes on right)”. The reduced or
mini size has layout and options restricted. But, it
comes with an AC-DC adapter since it has a 5V-to-

3.3V regulator on board. In contrast, the full size
version requires +5 and +3.3VDC supplies.

2) 10/100Mbs copper to 1300nm, 1X9 PECL module. See
attached schematic (Appendix B) labeled “ML6651
EVAL BOARD SCHEMATIC (9 pin module on right),
rev- A “. This full size board requires +5 and +3.3VDC
supplies and includes options for user defined
configuration purposes.

FEATURES

• Compatible with new TIA/EIA-785 10/100BASE-SX
standard. It is also intended to support ISO/IEC 8802.3
and IEEE 802.3 standards.

• Automatic detection and configuration of link for 10 or
100 Mbps operation using Auto-Negotiation protocol
(Transparent Mode)

• Supports Parallel Detection for speed configuration in
absence of FLP Bursts (Forced Mode)

• Supports SPEED and DUPLEX mode configuration in
absence of auto negotiation capability on fiber side

• Offers bandwidth migration from 10 Mbps to 100 Mbps
over fiber and copper networks

• Supports both miniature “sugar-cube” fiber-optic
components and PMD transceivers such as 1x9 (5V) or
MT-RJ (3.3V) PECL modules

• Multiple modes of operation for all network
configurations, especially Transparent Mode (see
ML6651 datasheet for more details)

• Transmission distance from 300 meters of multimode
fiber-optic cable up to 2 kilometers of singlemode fiber
optic cable

• Use 1:1 transformer ratio for TP’s transmit and receive
paths without requiring external filtering

• Integrated 100BASE-TX equalizer and baseline wander
correction circuits

3) 10/100Mbs copper to 1300nm, MT-RJ, PECL module.
See attached schematic (Appendix C) labeled
“ML6651 EVAL BOARD SCHEMATIC (MT-RJ on right),
rev-CMT”. Board requires +5 and +3.3VDC supplies,
full size only. This board is actually contructed by
using rev. A 1x9 PECL board above with different PCB
stuffing requirements. A daughter card is installed in
place of the 1X9 module. The daughter card carries the
MTRJ module and appropriate by-pass capacitors. The
schematic has reflected all the necessary changes:

1. The ML6651 Evaluation Board is ideally suited to
operate in Transparent mode. In this mode, the ML6651
will optimally and automatically configure for Ethernet
technology, depending on the capabilities of the system
link partners. This is the “plug-and-play” mode if there
is a common denominator between the two link
partners. This is also the default configuration of board
shipped.

2. For a complete discussion of the various modes,
Transparent, Non Transparent, and Forced, see the
ML6651 Datasheet.

Modes of Operation

To meet the needs of all network configurations the full size
version of the ML6651 Evaluation Board may be configured
to any of the following 3 modes of operation using the two
jumpers labeled SPEED and DUPLEX (Note: These modes
can also be set via Serial Management Interface (SMI)
register #30):

GENERAL DESCRIPTION

ML6651

Media Selections

The ML6651 has two interfaces to different media. One
interfaces only to fiber optic link. The other can interface to
either fiber optic link or copper link. The jumper locations
labeled PECL_QU and PECL_TP help to set the
configurations (can also be set via MII register #30). For the
mini size boards, the configuration is fixed so these jumpers
are not available.

Examples:

1. Full-length (100m) 10/100Mbs copper to 850nm/1300nm
miniature “sugar-cube” fiber optic components with
maximum fiber length of 2km: short J31 and J32

2. Full-length (100m) 10/100Mbs copper to PECL (1X9 pin
or MT-RJ module): short J31, J16, and J29

Status LEDs

Each of the media interfaces (TP or twisted-pair and FO or
fiber optic) has a set of three LEDs to indicate:

1) Data or Auto-Neg activities (D8, 9, RED)

2) Link speed is 10Mbs (D6, 7, YELLOW)

J26 is shorted to the FOAN_DT position, when not in TEST
mode.

J27 is shorted to the TPAN_DT position, not TEST.

J33-34 (FOINSPD, TPINSPD) must be shorted, also.

Do not change these settings.
Note: The mini size board will not have these jumpers, but
the LEDs are still available.

Miscellaneous

• J6, J25 (REFCLK): the ML6651 requires a 25MHz clock
source. J6 allows the board to select the on-board clock
oscillator (XTAL) at U4 or an alternate source. The
default position is on-board (XTAL). No jumper selection
for mini size boards.

• J28 (BCKPLINK): the ML6651 can enable a backup link
when the primary one is down when it is in Forced­100Mbs non-loopback mode. RED LED (BCKLINK) at
D10 will be lit. Please refer to data sheet for more
information. J28 is normally not installed for full size
board. It is installed for mini boards between pin #2,
and #3 to disable the feature.

• J29 (SDTH): installed if PECL module is used. No
jumper selection for mini size board.

• J23 (FOOUTOFF#): shorted to disable fiber optic driver.
Normally, it is not installed.

• J24 (TPOUTOFF#): shorted to disable twisted pair driver.
Normally, it is not installed.

• J35 (PWRDWN#): shorted to power down the ML6651.
Normally, it is not installed.

• J21 (PMD) : installed if PECL is selected instead of
Twisted-pair, (i.e., fiber to fiber conversion).

• J22 (MII power): If +5VDC is supplied through the MII
connector then this jumper must be shorted. Normally, it
is not installed since power is supplied via banana jacks
labeled +3.3V, +5V, and GND. No jumper selection for
mini size board.

• MII connector: allows optional access to a limited and
proprietary-defined set of registers, not available for mini
size board.

• PHY address jumpers: whenever the MII connector is
available, the proprietary MII registers can be accessed
via any one of the PHY address from 0 to 31 (decimal)
by setting up jumpers labeled AD10, AD32, and
AD4_LIW as follows: (short the corresponding jumpers
to achieve desired setting)

3) Link speed is 100Mbs (D11, 12, GREEN)

• SMA connectors: optional for external OSC, and optical
Tx/Rx signals (TD+/-, RD+/-), or for testing purposes.

Note: Not available for mini size board.

• Banana power jacks for +3.3V, +5V, and GND, not
available for mini size board which comes with AC to
+5VDC adapter and on-board 3.3V regulator.

Note: Always refer to schematic and data sheet for more details.

In summary, typical jumpers installed for each board are
shown below:

BOARD EVALUATION

Make sure the power is off when making electrical

connections. The operators should be grounded before
touching the board to minimize the threat of Electro Static
Discharge (ESD). Power is applied after all the connections
have been made. Normal operation and initialization
process begins at power up.

The following items are useful for testing and evaluating the
ML6651 Evaluation Board:

• Either of the two most popular optical fiber cable sizes,
50/125 micron or 62.5/125 micron multi mode fiber
cable can be used as the fiber link

• Fiber optic power meters (850/1300nm wave length)
such as the Fotec Power meter

• Fiber optic attenuators

• An optical to electrical converter. Micro Linear uses
the BCP waveform receiver model 300

• Network Interface Cards (NIC’s) or Netcom’s Fast
Ethernet (Smart Bits 2000) testers

• Twisted-pair cables of various lengths (100m Ethernet
Standard: max 100m) with crossover wiring

• The jumpers are installed as pre-configured

GENERAL DESCRIPTION

ML6651

TESTING

Install the twisted pair and fiber cables. Use the attenuators
in the fiber links if desired. The board’s RJ45 jack has a

straight or NIC wiring so be sure to use a crossover copper
cable or a separate crossover adapter.

The normal mode of operation is Transparent Mode, or plug­and-play mode, if a common denominator is found between
the two copper end ports.

The plug and play mode is as follows:

Connect the power source and turn it on. LEDs should start
to blink and finally are settled to either the 10Mbs or
100Mbs LEDs, whichever is the common speed (must be a
pair). It may take a few cycles with LEDs running up and
down if Auto-negotiation is taking place. If the AN_DT LEDs
keeps blinking or only one of the speed LED is ON instead
of a pair (both 10 or both 100), then no link has been
established. Recheck the configurations of your copper

stations and reconfigure the eval-board if needed (to Non­Transparent or Fixed mode).

If one of the TP link partner’s capabilities is changed, auto­negotiation may be restarted automatically by disconnecting
and reconnecting the cables. Alternatively, auto-negotiation
may be restarted from the Netcom’s SmartBits 2000 software
graphical interface. If no common operating mode is found
between two link partners the red (D8, D9 LED(s) will
remain flashing for the auto-negotiation capable link
partner(s) as long as FLP and FLNP bursts are received.

One way to test the ML6651 Evaluation Board is shown in
Figure 4. The Netcom SmartBit 2000 system can have its
port configured to look like a legacy or auto-negotiable
station. The configuration of the ML6651 eval board can be
changed accordingly. Once link is established, data (with
variable lengths and patterns) can be transferred from one
Netcom port and received at another.

To measure the launch power at the transmitter, disconnect
the fiber optic cable from the optical receiver module and
connect it to the power meter. Measure the power while the
pattern generator is transmitting. Note that the reading of the
power meter applies to the average launch power: Average
launch power (dBm) = peak launch power (dBm) minus
3dBm

To measure optical rise and fall time connect the fiber optic
cable from the optical transmitter to the optical waveform
receiver and then to the scope. You need to program the
data to a specific pattern like AAhex (not random).

To measure optical sensitivity use the variable attenuator to
attenuate the power. Start to transmit a random pattern and
then observe that the Link LED stays on. Then attenuate the
optical signal during transmission until the Link LED goes
off. Now slightly increase the optical signal through the
attenuator to turn the Link LED back on. Finally measure
the receive power by the power meter to find the receive
sensitivity.

Evaluation Board Errata

This applys to all four board configurations to avoid
confusion. Do not stuff C49 & C50 located upper right
corner of schematics on full size boards and top center on

11 Planes on PCB, Digital: 5v & 3.3v.
Analog: 5v RX (sugar cube), 9 pin mod
needs 5v TX & RX, and the DUT needs
5 analog planes; T, E, L, FC & BQ.
RJ45 + half magnetics on isolated
& no inner planes.
TX sugar cube uses L (3.3v, analog)
for power.
Each plane has separate bead (vcc &
gnd) and filter caps. Digital Gnds
share same gnd plane.

APPENDIX C: FULL SIZE BOARD REV. CMT WITH MT-RJ MODULE

ML6651

The following changes are made to the full-size board rev. A
(Appendix B) to construct rev. CMT board for MTRJ eval­board:

BOM changes:

· Remove L101,102

· R57 value is 2KΩ.

· R27,105,107 values are all 130 Ω.

· R28,106,108 values are all 82Ω.

· R103 value is 1KΩ.

· R104 value is 1.6KΩ.

Install wire jumpers from:

· C104 + TO C45+

· C103+ TO C32+

Reverse C103 placement since silk-screen is backward.

Note: This full size board rev CMT with the MT-RJ modules
shares the same PC board as the Appendix B. Use the
Appendix B board layout with the MT-RJ daughter board.

11 Planes on PCB, Digital: 5v & 3.3v.
Analog: 5v RX (sugar cube), 9 pin
mod
needs 5v TX & RX, and the DUT
needs
5 analog planes; T, E, L, FC & BQ.
RJ45 + half magnetics on isolated
& no inner planes.
TX sugar cube uses L (3.3v, analog)
for power.
Each plane has separate bead (vcc &
gnd) and filter caps. Digital Gnds

share same gnd plane.
