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 ■ Power down mode with very low Th e d i g i t a l b a s e b a n d features fast symbol clock-recovery supply current (1 µA typ.) the receiver application. The device can switch between two configurations. ■ Low supply current (< 8 mA active mode, Applications ■ Remote Keyless Entry (RKE) and Passive Keyless Entry (PKE) systems ■ Tire Pressure Monitoring (TPM) systems < 50 µA self polling mode) ■ Two supply voltage ranges possible: 3.3 V ±10% or 5 V ±10% ■ Remote control systems ■ Alarm systems ■ Temperature range -40°C … +105°C ■ Low bit rate communication systems ■ Digital Baseband Processing with – Configurable data-filter – Fast symbol clock-recovery Ordering Information – Frame-synchronization for automatic Type Ordering Code Package TDA5230 SP000076520 PG-TSSOP-28-1 TDA5231 SP000202847 payload-extraction – Message content screening PG-TSSOP-28-1 – Dual configuration capability – FIFO-data buffer Evaluation Kits Type Modulation Frequency Ordering Code WLC-B TDA5230-434 ASK/FSK 434 MHz On request WLC-B TDA5230-868 ASK/FSK 868 MHz On request WLC-B TDA5231 ASK/FSK 315 MHz On request www.infineon.com/wirelesscontrol Wireless Control ■ Digitally trimmable crystal oscillator ■ External LNA controlled by receiver Product Brief Block Diagram TDA523x 90˚ LNA Image Reject Downconverter 10.7 MHz IF Filter + Digital FSK Demodulator Configurable Data-Filter P-ON Fast Symbol Frame Recovery RSSI Frame Synchronization Gain Control A Q D Message Content Screening 315/434/868 MHz PLL Synth.
