FIN24AC PSerDes¥ 22-Bit Bi-Directional Serializer/Deserializer September 2005 Revised December 2005 FIN24AC PSerDes¥ 22-Bit Bi-Directional Serializer/Deserializer General Description Features O Low power for minimum impact on battery life The FIN24AC P SerDes¥ is a low power Serializer/Deserializer (SerDes) that can help minimize the cost and power of transfer Multiple power-down modes ring wide signal paths. Through the use of serialization, the AC coupling with DC balance number of signals transferred from one point to another can be O 100nA in standby mode significantly reduced. Typical reduction is 4:1 to 6:1 for unidirec5mA typical operating conditions tional paths. For bi-directional operation, using half duplex for O Cable reduction: 25:4 or greater multiple sources, it is possible to increase the signal reduction to close to 10:1. Through the use of differential signaling, shieldO Bi-directional operation 50:7 reduction or greater ing and EMI filters can also be minimized, further reducing the O Differential signaling: cost of serialization. The differential signaling is also important 90dBm EMI when using CTL in lab conditions using a near for providing a noise-insensitive signal that can withstand radio field probe and electrical noise sources.
