Description
The FIN12AC is a 12-bit serializer / deserializer capable
of running a parallel frequency range between 5MHz
and 40MHz, selected by the S1 and S2 control signals.
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 hardwir-
ing the DIRI pin. An internal Phase-Locked Loop (PLL)
generates the required bit clock frequency for transfer
across the serial link. Options exist for dual or single PLL
operation, dependent upon system operational parame-
ters. The device has been designed for low power opera-
tion and utilizes Fairchild proprietary low-power control
Current Transistor Logic (CTL™) interface. The device
also supports an ultra low power power-down mode for
conserving power in battery-operated applications.

... Control Logic Circuitry The FIN12AC can be used as a 12-bit serializer or a 12- bit deserializer. Terminals S1 and S2 must be set to accommodate the clock reference input frequency range of the serializer.

... STROBE Pass-Through Mode For some applications desirable to pass a word clock across a differential signal pair in the opposite direction of serialization. The FIN12AC supports this mode of operation. For the deserializer: 1. DIRI = LOW 2. CKREF = LOW 3. Word clock should be connected to the STROBE. This passes the STROBE signal out the CKSO port. ...
