Description
The FIN12AC is a 12-bit serializer capable of running a
parallel frequency range between 5MHz and 40MHz.
The frequency range is selected by the S1 and S2 con-
trol signals. The bi-directional data flow is controlled
through use of a direction (DIRI) control pin. The devices
can be configured to operate in a unidirectional mode
only by hardwiring the DIRI pin. An internal Phase-
Locked Loop (PLL) generates the required bit clock fre-
quency for transfer across the serial link. Options exist
for dual or single PLL operation, dependent upon system
operational parameters. The device has been designed
for low power operation and utilizes Fairchild proprietary
low-power control Current Transistor Logic (CTL) inter-
face. The device also supports an ultra low power power-
down mode for conserving power in battery-operated
applications.
