RXC101 is a highly integrated single chip, zero-IF, multi-channel, lowpower, high data rate RF receiver designed to operate in the unlicensed315/433/868 and 915 MHz frequency bands. All critical RF and basebandfunctions are completely integrated in the chip, thus minimizing externalcomponent count and simplifying design-ins. Its small size with low powerconsumption makes it ideal for various short range radio applications.The RXC101 supports two modes – Micro controller mode and Standalonemode. In the Micro controller mode, the use of a generic 10MHz crystaland a low-cost microcontroller is all that is needed to create a completeReceiver link. Simple short range radio applications can be supported byusing the RXC101 in the Standalone mode, which allows complete receiveroperation without the use of a microcontroller.
