Reference Design
Agilent has developed a reference
design for multimode and single-
mode OC-12 ATM-SONET/SDH
applications shown in Figure 6.
This reference design uses a
Vitesse Semiconductor Inc.’s
VSC8117 clock recovery/clock
generation/serializer/deserializer
integrated circuit and a PMC-
Sierra Inc. PM5355 framer IC.
Application Note 1178 documents
the design, layout, testing and
performance of this reference
design. Gerber files, schematic
and application note are available
from the Agilent Fiber-Optics
Components’ web site at the URL
of http://www.semiconductor.

Operation in -5.2 V Designs
For applications that require
-5.2 V dc power supply level for
true ECL logic circuits, the
HFBR/HFCT-5208M transceiver
can be operated with a VCC = 0 V
dc and a VEE = -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 VOH
and VOL will be changed slightly
due to the 0.2 V difference in
supply levels. Also, noise
immunity may be compromised
for the HFBR/HFCT-5208M trans-
ceiver because the ground plane is
now the VCC supply point. The
suggested power supply filter
circuit shown in the Recommended
Circuit Schematic figure should be
located in the VEE paths at the
transceiver supply pins. Direct
coupling of the differential data
signal can be done between the
HFBR-5208M transceiver and the
standard ECL circuits. For
guaranteed -5.2 V dc operation,
contact your local Agilent
Component Field Sales Engineer
for assistance.
Electromagnetic Interference (EMI)
One of a circuit board designer’s
foremost concerns is the control
of electromagnetic emissions
from electronic equipment.
Success in controlling generated
Electromagnetic Interference
(EMI) enables the designer to pass
a governmental agency’s EMI
regulatory standard; and more
importantly, it reduces the
possibility of interference to
neighboring equipment. There are
three options available for the
HFBR/HFCT-5208M with regard to
EMI shielding for providing the
designer with a means to achieve
good EMI performance. The EMI
performance of an enclosure
using these transceivers is
dependent on the chassis design.
Agilent encourages using standard
RF suppression practices and
avoiding poorly EMI-sealed
enclosures. In addition, Agilent
advises that for the best EMI
performance, the metalized case
must be connected to chassis
ground using one of the shield
options.
