General Description
The FIN224AC µSerDes™ is a low-power serializer/deserializer (SerDes) that can help minimize the cost
and power of transferring wide signal paths. Through the
use of serialization, the number of signals transferred
from one point to another can be significantly reduced.
Typical reduction is 4:1 to 6:1 for unidirectional paths.
For bidirectional operation, using half duplex for multiple
sources, it is possible to reach signal reduction close to
10:1. Through the use of differential signaling, shielding
and EMI filters can also be minimized, further reducing
the cost of serialization. The differential signaling is also
important for providing a noise-insensitive signal that can
withstand radio and electrical noise sources. Major
reduction in power consumption allows minimal impact
on battery life in ultra-portable applications. It is possible
to use a single PLL for most applications including bidirectional
operation.
