FIN424C: 20-Bit Ultra-Low Power Serializer Supporting uController and RGB Displays

The FIN424C and FIN425C µSerDes™ are a low-power serializer/ deserializer pair that can help minimize the cost and power of an LCD interface. They are designed to operate transparently between the baseband processor and LCD. /WE and chip-select timing is maintained from the serializer to the deserializer. Through the use of serialization, the number of signals transferred from one point to another can be significantly reduced. Typical reduction is 5:1. Through the use of differential signaling, shielding, and EMI filters can also be minimized, further reducing the cost of serialization. Differential signaling is important for providing a noise-insensitive signal that can withstand radio and electrical noise sources. Major reduction in power consumption allows minimal impact on battery life in mobile applications.
