Low Voltage 24-Bit Bi-Directional Serializer/Deserializer
with Multiple Frequency Ranges (Preliminary)
General Description
The FIN24A allows for a pair of SerDes to interleave data
from two different data sources going opposite directions or
standard bi-directional interface operation. The bi-direc-
tional data flow is controlled through use of a direction
(DIRI) control pin. The devices can be configured to oper-
ate in a unidirectional mode only by hardwiring the DIRI
pin. An internal PLL generates the required bit clock fre-
quency for transfer across the serial link. The FIN24A sup-
ports multiple input frequency ranges which are selected
by the S1 and S2 control pins. Options exist for dual or sin-
gle PLL operation dependent upon system operational
parameters. The device has been designed for low power
operation and utilizes Fairchild Low Power LVDS interface.
The device also supports an ultra low power Power-Down
mode for conserving power in battery operated applica-
tions.
