Family Frequently Asked Questions (FAQs)
Summary
The following questions are typical of Fairchild’s
µSerDes™ application support team answers the µSerDes
family. If you have a question not addressed here, please
contact your local Fairchild representative or email to
[e-mail].
What is a µSerDes™?
The µSerDes is a low-cost, ultra-low EMI, very small
device that allows large amounts of data to flow between
points such as displays, cameras, and controllers. This is
achieved through a parallel-to-serial (serializer) conversion
at the source and serial-to-parallel (deserializer) conversion
at the destination.
Why is a Fairchild µSerDes™ serial interface better
than a parallel interface solution?
ƒ Significantly reduced EMI over single-ended
technology solutions.
ƒ No power-up sequencing required. No change needed
for controller software.
ƒ Functions well where single-ended, current-mode
technology fails.
ƒ Can provide a greater than 25 to 4 wire reduction.
ƒ Can provide a greater than 50 to 7 wire reduction in bi-
directional interfaces.
ƒ Can provide a lower-cost, more reliable interface
solution.
ƒ Can reduce overall component count over existing
LVCMOS technology.
ƒ Can use less board space over LVCMOS technologies.
