TDA5204

RF Receivers Overview

The Infineon TDA5204 is an obsolete ASK single-conversion RF receiver operating within the 385MHz to 406MHz frequency range. It features a sensitivity of -107dBm and supports data rates up to 112kcps. The device requires a 5V power supply and draws 4.6mA during reception. It is housed in a 28-TSSOP package with a width of 4.40mm, designed for surface-mount installation. The operational temperature range spans from -40°C to +85°C.

RF Receivers Feature Summary

• Integrates a low noise amplifier, double balanced mixer, fully integrated VCO, PLL synthesizer, and crystal oscillator.
• Includes a limiter circuit with Received Signal Strength Indicator (RSSI) functionality.
• Supports ASK modulation protocols for wireless communication applications.

RF Receivers Applications

• Alarm systems
• Communication systems

RF Receivers Procurement Notes

Verify component authenticity through authorized channels as this part is officially obsolete. Check datasheet revisions for specific pinout configurations and handling instructions. Ensure design-in compatibility with existing PCB layouts due to the 28-TSSOP package dimensions. Confirm that replacement strategies are established given the discontinuation status.

RF Receivers Selection Notes

Select this component only if the application strictly requires the 385MHz to 406MHz band and ASK modulation. Consider the obsolete status when planning long-term production cycles. Evaluate thermal requirements against the -40°C to +85°C operating range. Verify that the 5V supply voltage aligns with system power architecture constraints.

RF Receivers Part Context

The TDA5204 belongs to Infineon's legacy RF receiver portfolio, utilizing silicon technology for sub-GHz applications. It represents a single-chip solution combining analog front-end processing with digital control interfaces. The device was designed for cost-effective integration in remote control and telemetry systems requiring reliable short-range communication.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The TDA5200 is listed as a related product but operates at 870MHz and is also obsolete. Designers should consult official Infineon resources for current active alternatives compatible with similar frequency bands.
