Overview
The TDA523x is a family of universal, highly sensitive, low-power single-chip ASK/FSK superheterodyne image-reject-receivers for Manchester-coded data signals in the ISM bands between 302..320 MHz, 433..450 MHz and 865..870 MHz. The chips include fully-integrated digital baseband data processing and produce clean data output via SPI, thus significantly reducing the load on the host processor and standby power consumption. The TDA523x family of chips offers a high level of integration and needs only few external components for application deployment.
