Description
The conductive port option for
the Low Cost Miniature Link
component family consists of a
grounding path from the
conductive port to four
grounding pins as shown in the
package outline drawing. Signal
ground is separate from the four
grounding pins to give the
designer more flexibility. This
option is available with all SMA
and ST panel mount styled port
receivers. Electrical/optical
performance of the receivers is
not affected by the conductive
port. Refer to the HFBR-0400
data sheets for more information.

Applications
HP recommends that the designer
use separate ground paths for the
signal ground and the conductive
port ground in order to minimize
the effects of coupled noise on
the receiver circuitry. If the
designer notices that extreme
noise is present on the system
chassis, care should be taken to
electrically isolate the conductive
port from the chassis.
In the case of ESD, the conduc-
tive port option does not alleviate
the need for system recovery
procedures. A 15 kV ESD event
entering through the port will not

cause catastrophic failure for any
HFBR-0400 receivers, but may
cause soft errors. The conductive
port option can reduce the
amount of soft errors due to ESD
events, but does not guarantee
error-free performance.
