RC-RFSK1-434.5N

RF Receivers Overview

The RC-RFSK1-434.5N is a Frequency Shift Keying (FSK) radio receiver module manufactured by RadioControlli, designed for operation at the 434.5 MHz frequency band. This component integrates a Phase-Locked Loop (PLL) synthesizer and a crystal oscillator to ensure stable signal reception. It operates on a single 5-volt supply and features a power-down mode for energy efficiency. The module supports data rates up to 4.8 kbps and achieves a receiver sensitivity of -118 dBm. It is housed in a 15-pin Single In-line Package (SIP) with through-hole mounting technology, measuring approximately 18.3 x 38.1 mm.

RF Receivers Feature Summary

• Integrates PLL synthesizer and crystal oscillator for stable FSK reception
• Supports low-power operation via dedicated power-down mode
• Utilizes through-hole SIP packaging for robust board integration

RF Receivers Applications

• Home automation systems
• Building automation applications
• Wireless door control kits

RF Receivers Procurement Notes

Verify the specific frequency variant required for your region's regulatory compliance, as the RC-RFSK1 series includes multiple frequency options such as 433.92 MHz and 434.15 MHz. Confirm that the 15-SIP through-hole footprint matches your PCB design constraints. Ensure the system voltage aligns with the module's 5V operating requirement and check if the included datasheet specifies any additional external components necessary for optimal performance.

RF Receivers Selection Notes

Select this module when a dedicated FSK receiver with integrated PLL synthesis is required for 434.5 MHz applications. Consider the -118 dBm sensitivity figure for link budget calculations in environments requiring reliable long-range communication. The choice between ASK and FSK modulation should be based on noise immunity requirements, with FSK offering better performance in noisy conditions. Verify that the physical dimensions and through-hole mounting style fit within the mechanical enclosure and assembly process limitations.

RF Receivers Part Context

The RC-RFSK1-434.5N belongs to the RC-RFSK1-XXXN family of FSK radio receiver modules from RadioControlli. This family shares common architectural features, including the use of a PLL synthesizer, crystal oscillator, and 5V single-line package operation. Variants within the series are distinguished primarily by their operating frequency, such as the 433.92 MHz or 434.15 MHz models, allowing designers to select the appropriate spectral allocation while maintaining consistent interface and functional characteristics across the product line.

RF Receivers Replacement Considerations

Direct substitutes include other frequencies within the same RC-RFSK1 series, such as the RC-RFSK1-433.92N or RC-RFSK1-434.15N, provided the target application permits the frequency change. No alternative manufacturers are explicitly confirmed in the provided documentation.
