capacitors. Also, it is recom-
mended that a surface-mount coil
inductor of 1
μ
H be used. Ferrite
beads can be used to replace the
coil inductors when using quieter
V
CC
supplies, but a coil inductor
is recommended over a ferrite
bead. Coils with a low, series dc
resistance (<0.7 ohms) and high,
Self-resonating frequency are
recommended. All power supply
components need to be placed
physically next to the V
CC
pins of
the receiver and transmitter. Use
a good, uniform ground plane
with a minimum number of holes
to provide a low-inductance
ground current return for the
power supply currents.
In addition to these recommenda-
tions, Hewlett-Packard’s Applica-
tion Engineering staff is available
for consulting on best layout
practices with various vendors
mux/demux, clock generator and
clock recovery circuits. HP has
participated in several reference
design studies and is prepared to
share the findings of these
studies with interested customers.
Contact your local HP sales
representative to arrange for this
service.
Evaluation Circuit Boards
Evaluation circuit boards
implementing this recommended
circuit design are available from
Hewlett-Packard’s Application
Engineering staff. Contact your
local HP sales representative to
arrange for access to one if
needed.
Operation in -5.2 V Designs
For applications that require
-5.2 V dc power supply level for
true ECL logic circuits, the
HFCT-5202 transceiver can be
operated with a V
CC
= 0 V dc and
a V
EE
= -5.2 V dc. This
transceiver is not specified with
an operating, negative power
supply voltage. The potential
compromises that can occur with
use of -5.2 V dc power are that
the absolute voltage states for
V
OH
and V
OL
will be changed
slightly due to the 0.2 V differ-
ence in supply levels. Also, noise
immunity may be compromised
for the HFCT-5202 transceiver
because the ground plane is now
the V
CC
supply point. The
suggested power supply filter
circuit shown in Figure 4
Recommended Circuit Schematic
should be located in the V
EE
paths at the transceiver supply
pins. Direct coupling of the
differential data and clock signals
can be done between the HFCT-
5202 transceiver and the
standard ECL circuits. For
guaranteed -5.2 V dc operation,
contact your local Hewlett-
Packard Field Sales Engineer for
assistance.
Recommended Solder and
Wash Process
The HFCT-5202 is compatible
with industry standard wave or
hand solder processes.
HFCT-5202 Process Plug
The HFCT-5202 transceiver is
supplied with a process plug for
protection of the optical ports
with the Duplex SC connector
receptacle. This process plug
prevents contamination during
wave solder and aqueous rinse as
well as during handling, shipping,
or storage. It is made of high-
temperature, molded, sealing
material that will withstand
+80
°
C and a rinse pressure of
50 lb/in
2
.
Recommended Solder Fluxes
and Cleaning/Degreasing
Chemicals
Solder fluxes used with the
HFCT-5202 fiber-optic
transceiver should be water-
soluble, organic solder fluxes.
Some recommended solder fluxes
are Lonco 3355-11 from London
Chemical West, Inc. of Burbank,
CA, and 100 Flux from Alpha-
metals of Jersey City, N.J.
Recommended cleaning and
degreasing chemicals for the
HFCT-5202 are alcohols (methyl,
isopropyl, isobutyl), aliphatics
(hexane, heptane), and other
chemicals, such as soap solution
or naphtha. Do not use partially
halogenated hydrocarbons for
cleaning/degreasing. Examples of
chemicals to avoid are 1.1.1.
trichloroethane, ketones (such as
MEK), acetone, chloroform, ethyl
acetate, methylene dichloride,
phenol, methylene chloride, or
N-methylpyrolldone.
Regulatory Compliance
The HFCT-5202 is intended to
enable commercial system
designers to develop equipment
that complies with the various
regulations governing certifica-
tion of Information Technology
Equipment. See the Regulatory
Compliance Table 1 for details.
Additional information is
available from your Hewlett-
Packard sales representative.
Electrostatic Discharge (ESD)
Normal ESD handling precautions
for ESD sensitive devices should
be followed while using the
HFCT-5202. These precautions
include using grounded wrist
straps, work benches, and floor
mats in ESD controlled areas.
