Low Voltage 12-Bit Bi-Directional Serializer/Deserializer
with Multiple Frequency Ranges (Preliminary)
General Description
The FIN12AC is a 12-bit serializer capable of running a
parallel frequency range between 5MHz and 56MHz. The
frequency range is selected by the S1 and S2 control sig-
nals. The bi-directional data flow is controlled through use
of a direction (DIRI) control pin. The devices can be config-
ured to operate in a unidirectional mode only by hardwiring
the DIRI pin. An internal PLL generates the required bit
clock frequency for transfer across the serial link. Options
exist for dual or single PLL operation dependent upon sys-
tem operational parameters. The device has been
designed for low power operation and utilizes Fairchild Pro-
prietary Low Power CTL interface. The device also sup-
ports an ultra low power Power-Down mode for conserving
power in battery operated applications.
