General Description
The FIN24C 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 bi-directional operation, using half duplex for multiple
sources, it is possible to increase the signal reduction to
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 signal-
ing is also important for providing a noise-insensitive sig-
nal that can withstand radio and electrical noise sources.
Major reduction in power consumption allows minimal
impact on battery life in ultra-portable applications. A
unique word boundary technique assures that the actual
word boundary is identified when the data is deserial-
ized. This guarantees that each word is correctly aligned
at the deserializer on a word-by-word basis through a
unique sequence of clock and data that is not repeated
except at the word boundary. A single PLL is adequate
for most applications, including bi-directional operation.
