Abstract :
This ultra-low-power FSK receiver is targeted at both deep-space and terrestrial applications. In addition to demodulation, the chip integrates all-digital timing plus carrier acquisition and tracking loops. The receiver is flexible and configurable, supporting data rates variable over two orders of magnitude, It processes 1 b quantized RF input (F/sub c/=437.1 MHz) in the deep-space mode of operation and a multi-bit baseband input in the terrestrial mode. The 1 b input mode allows for significant power savings but is not readily usable in terrestrial applications due to the effects of intermodulation.
