TDA 5201 is a single conversion receiver for wireless components
The document provides a complete description of the Infineon TDA5201 ASK Single Conversion Receiver, a low‑power, single‑chip super‑heterodyne receiver for 315 MHz and 345 MHz bands. It outlines the integrated functions such as the low‑noise amplifier, double‑balanced mixer, VCO with PLL synthesiser, crystal oscillator, limiter with RSSI generator, data filter, data slicer, and peak detector, as well as a power‑down mode for battery‑saving operation.
Additional sections cover package details (P‑TSSOP‑28‑1), pin configuration and definitions, functional block diagrams, electrical characteristics (supply current, voltage range, input sensitivity), absolute maximum ratings, AC/DC characteristics, test circuits, and a bill of materials. The specification also includes application notes for keyless entry, remote control, fire alarm, and low‑bitrate communication systems.
