Operation in -5.2 V Designs
For applications that require
-5.2 V dc power supply level for
true ECL logic circuits, the
HFBR-5208 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 volt-
age states for V
OH
and V
OL
will be
changed slightly due to the 0.2 V
difference in supply levels. Also,
noise immunity may be compro-
mised for the HFBR-5208 trans-
ceiver because the ground plane
is now the V
CC
supply point. The
suggested power supply filter
circuit shown in the Recommended
Circuit Schematic figure should
be located in the V
EE
paths at the
transceiver supply pins. Direct
coupling of the differential data
signal can be done between the
HFBR-5208 transceiver and the
standard ECL circuits. For
guaranteed -5.2 V dc operation,
contact our local Hewlett-
Packard Component Field Sales
Engineer for assistance.
Recommended Solder
and Wash Process
The HFBR-5208 is compatible
with industry-standard wave or
hand solder processes.

HFBR-5000 Process Plug
The HFBR-5208 transceiver is
supplied with a process plug, the
HFBR-5000, for protection of the
optical ports with the Duplex SC
connector receptacle. This
process plug prevents contami-
nation 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
HFBR-5208 fiber-optic trans-
ceiver 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, NJ.
Recommended cleaning and
degreasing chemicals for the
HFBR-5208 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.
