The FIN324C is a 24-bit serializer / deserializer with dual strobe inputs. The device can be configured as a master or slave device through the master/slave select pin (M/S). This allows for the same device to be used as either a serializer or deserializer, minimizing component types in the system. The dual strobe inputs allow implementation of dual-display systems with a single pair of µSerDes. The FIN324C can accommodate RGB, microcontroller, or SPI mode interfaces. Read and write transactions are supported when operating with a microcontroller interface for one or both displays. Unlike other SerDes solutions, no external timing reference is required for operation.

The FIN324C is designed for ultra-low power operation. Reset (/RES) and standby (/STBY) signals put the device in an ultra-low power state. In standby mode, the outputs of the slave device maintain state, allowing the system to resume operation from the last-known state.

The device utilizes Fairchild’s proprietary ultra-low power, low-EMI Current Transfer Logic™ (CTL) technology. The serial interface disables between transactions to minimize EMI at the serial interface and to conserve power. CMOS parallel output buffers have been implemented with slew rate control to adjust for capacitive loading and to minimize EMI.
