Product Brief
SmartLEWIS TM RX
TDA523x Series
ASK/FSK Autonomous Receiver Family
W i r e l e s s C o n t r o l – The TDA523x series is a family of autonomous
ASK/FSK receivers for the frequency bands 302 – 320 MHz, 433 – 450 MHz, and
Features
■
Frequency ranges
865 – 870 MHz. A fully integrated RF-synthesizer offers multi-channel capability. The
302 – 320 MHz, 433 – 450 MHz and
IC integrates an image-reject RF-front-end together with digital base band processing.
865 – 870 MHz
■
ASK/FSK demodulation
■
Fully integrated RF-synthesizer
based on a digital PLL plus automatic extraction of telegrams from run-in data.
■
Multi-channel capability
Data telegram can be screened for IDs before being stored in a FIFO-data buffer.
■
ASK sensitivity < -108 dBm @ 434 MHz
Autonomous self-polling reduces power-consumption because it off-loads the host in
