TDA5200 Descripción general
An ASK single-conversion receiver is a type of RF receiver that downconverts the incoming radio signal to a single intermediate frequency using one mixing stage, then recovers the transmitted data by detecting amplitude variations of the carrier. Within the system hierarchy, it belongs to the short-range wireless category of RF receivers, which sits below RF transceivers (which add a transmit path) and above complete wireless modules, and forms the analog front end of a remote-control or telemetry link together with a microcontroller decoder.
Key features of the TDA5200 include a high level of integration, meaning only a few external components are needed to build a complete receiver chain, and dual-band support covering both the European 868 MHz SRD band and the widely used 433 MHz band. Very low power consumption makes the device well suited to battery-powered remote keyless entry and telemetry nodes, and the automotive qualification extends its use to vehicle subsystems.
From a technical standpoint, the receiver uses a single-conversion architecture with an on-chip local oscillator, typically controlled by a quartz crystal, whose load capacitance is selected according to the negative resistance of the oscillator circuit as described in the manufacturer datasheet. The LNA, mixer, IF limiting amplifier, and ASK demodulator are all integrated, minimizing BOM count and board area while improving repeatability in volume production.
Typical applications include 868 MHz and 433 MHz remote keyless entry receivers, garage door openers, wireless alarm and security sensors, and low-rate industrial telemetry links, where its sensitivity and low current draw directly extend battery life and link reliability.
When designing with the TDA5200, pay close attention to crystal load capacitance and PCB layout of the RF front end; matching network values and grounding strongly influence sensitivity and selectivity in the 433 MHz and 868 MHz bands.

Aplicaciones típicas
TDA5200 es adecuado para 6 aplicacións: Remote Keyless Entry (RKE) Receivers, 868 MHz SRD Telemetry, Wireless Alarm and Security Sensors, Garage Door and Gate Openers, Industrial Telemetry and Control Links, Smart Home and IoT Sensor Hubs.
Remote Keyless Entry (RKE) Receivers
The TDA5200 fits automotive and building remote keyless entry receivers because it combines a 433-435 MHz and 868-870 MHz ASK receive path with very low power consumption in a single 28-pin TSSOP chip rated for automotive use per distributor listings. In a typical RKE design, the ICs LNA feeds an integrated single-conversion mixer, and the ASK demodulator outputs baseband data directly to the vehicle or door-controller microcontroller for rolling-code decoding. Because only a few external components are required, the RF front end can be kept small and cost-optimized. The quartz-referenced local oscillator provides stable frequency operation across the automotive temperature range when the crystal load capacitance is set per the datasheet oscillator chapter.

868 MHz SRD Telemetry
For European 868-870 MHz short-range-device telemetry links, the TDA5200 provides a dedicated ASK single-conversion receiver front end operating from a 5 V rail. Its high integration means the LNA, mixer, IF amplifier, and demodulator are on-chip, so a telemetry node needs only a matching network, crystal, and a few passives to complete the RF path. The very low power consumption extends battery life in metering, sensor-node, and status-reporting applications that transmit intermittent short packets. The ASK modulation scheme keeps the demodulator simple and cost-effective for low data-rate telemetry, while the quartz-controlled oscillator maintains channel accuracy across the industrial temperature grade specified in distributor data.

Wireless Alarm and Security Sensors
Wireless alarm panels and door/window sensors in the 433-435 MHz band benefit from the TDA5200's ASK receiver architecture: amplitude-shift keying is simple and robust for on/off event signaling, and the single-conversion receiver delivers adequate sensitivity with minimal board area. The very low power consumption allows battery-powered sensor nodes to poll or listen for long periods, and the industrial temperature grade covers unconditioned installations such as garages and outdoor PIR sensor enclosures. Because the TDA5200 requires only a few external components, sensor manufacturers can standardize one compact RF module across both the 433 MHz and 868 MHz regional variants, reducing qualification effort and inventory complexity across markets.

Garage Door and Gate Openers
Garage door openers and automatic gate controllers are classic 433-435 MHz ASK applications where the TDA5200 excels. The receivers single-conversion architecture and integrated ASK demodulator recover the transmitted command codes directly, and the quartz-stabilized local oscillator keeps the receive channel aligned with low-cost handheld transmitter fobs. The 5 V supply integrates naturally into legacy opener control boards that already run 5 V logic, eliminating an extra regulator. Distributor data notes automotive ratings, so the same receiver design can serve both consumer opener units and vehicle-integrated HomeLink-style receivers. Low external component count keeps the RF section small enough for the opener head-unit PCB.

Industrial Telemetry and Control Links
In factory and process environments, short-range 868 MHz or 433 MHz ASK links carry crane remote controls, machine status signals, and small telemetry payloads. The TDA5200's industrial temperature grade and 5 V operation suit these control cabinets and handheld transmitter units, while its very low power consumption matters in battery-powered handheld pendants. The high level of integration reduces RF tuning labor in volume production, an important cost factor for industrial equipment built in moderate volumes. The quartz oscillator loading procedure described in the Infineon TDA5200_DS_V3.0 datasheet lets designers hit channel frequency accuracy without lab iterations, and the ASK demodulator drives standard microcontroller inputs for command decoding.

Smart Home and IoT Sensor Hubs
Smart home hubs listening for 433 MHz sensor traffic (door sensors, PIR detectors, weather stations) can use the TDA5200 as a dedicated receive front end. Its dual-band 433-435 MHz and 868-870 MHz coverage allows one hardware platform to serve multiple regional product variants, and ASK demodulation handles the vast installed base of low-cost OOK/ASK sensors. The very low power consumption suits always-on hub receivers, and the 5 V supply interfaces directly with many hub logic rails. Because the IC needs only a few external components, hub makers can integrate the RF path on the main board, avoiding a separate module and reducing bill-of-materials cost for consumer price-sensitive products.

Notas de diseño
Layout the RF front end with a continuous ground plane under the TDA5200 and keep the LNA input matching network as short as possible to the antenna pin. Place the quartz crystal and its load capacitors close to the oscillator pins; per the Infineon TDA5200_DS_V3.0 datasheet, the load capacitor value is determined by the reactive part of the oscillator negative resistance (Chapter 5.1.3) plus the crystal manufacturer specifications, so finalize these values on the real PCB where stray capacitance is known.
Decouple the 5 V supply with a combination of a bulk capacitor and a 100 nF ceramic placed within a few millimeters of the supply pin. The TDA5200 is specified for very low power consumption, but the RF stages are sensitive to supply ripple, which can mix into the single-conversion IF path and raise the noise floor. Route the supply as a star from a clean regulator output, and avoid sharing supply traces with digital microcontroller switching loads on the same board.
Do not assume family members are pin-identical: the TDA5201, TDA5211, and TDA5230 belong to the same Infineon short-range RF family but may differ in pinout, configuration, and sensitivity. Before any substitution, diff the pin tables in each datasheet and re-check the matching network values for the 433 MHz versus 868 MHz band variant. Also confirm RoHS/material compliance documentation directly with Infineon, since current listings do not state it.
Información de cumplimiento
Distributor listings describe the TDA5200 as an automotive RF receiver, but formal RoHS/REACH/AEC-Q100 qualification status was not found in the provided data and must be confirmed via the official Infineon product page.
