Family Frequently Asked Questions (FAQs)
Summary
The following questions are typical of Fairchild's uSerDesTM application support team answers the uSerDes family. If you have a question not addressed here, please contact your local Fairchild representative or email to interface@fairchildsemi.com. Why is a Fairchild uSerDesTM 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 bidirectional 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.
What is a uSerDesTM? The uSerDes 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.
