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

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?

Significantly reduced EMI over single-ended

technology solutions.

No power-up sequencing required. No change needed

for controller software.

Functions well where single-ended, current-mode

technology fails.

Can provide a greater than 25 to 4 wire reduction.

Can provide a greater than 50 to 7 wire reduction in bi-

directional interfaces.

Can provide a lower-cost, more reliable interface

solution.

Can reduce overall component count over existing

LVCMOS technology.

Can use less board space over LVCMOS technologies.
