Low Voltage 24-Bit Bi-Directional Serializer/Deserializer
General Description
The FIN24C
P
SerDes
樓
is a low power Serializer/Deserializer
(SerDes) that can help minimize the cost and power of transfer-
ring 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 unidirec-
tional 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, shield-
ing 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 con-
sumption 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. It is possible to use a single PLL for most appli-
cations including bi-directional operation.
