... Low Voltage 12-Bit Bi-Directional Serializer/Deserializer with Multiple Frequency Ranges (Preliminary) General Description The FIN12A is a 12-bit serializer capable of running a par- allel frequency range between 5MHz and 56MHz. The fre- quency range is selected by the S1 and S2 control signals. The bi-directional data flow is controlled through use of a direction (DIRI) control pin ...

... Other layout orientations may require that traces or cables cross. Control Logic Circuitry The FIN12A has the ability to 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 ...

... LVDS by sourcing and sinking a balanced current through the output pair. Like LVDS an input source termination resistor is required to develop a voltage at the differential input pair. The FIN12A device incorporates an internal ter- mination resistor on the CKSI receiver and a gated internal termination resistor on the DS input receiver. The gated ter- mination resistor insures proper termination regardless of direction of data flow ...
