FIN12AC

PSerDes¥

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.
