RCASK2-315

RF Receivers Overview

The RCASK2-315 is a 315MHz AM superheterodyne receiver module featuring a PLL synthesizer and crystal oscillator. It supports ASK/OOK modulation with an RF sensitivity of -107dBm and a maximum data rate of 4.8 kbps. The module operates on a supply voltage of 4.5V to 5.5V DC, consumes current in shut-down mode, and includes a squelch circuit. It utilizes a standard European pinout and offers a SIL version with power-down capability.

RF Receivers Feature Summary

• Superheterodyne architecture with PLL synthesizer for stable reception
• Integrated squelch circuit for noise reduction
• Standard European pinout configuration
• Power-down capability available in SIL version

RF Receivers Applications

• Ultra-high frequency wireless communication in the ISM band
• Remote control systems requiring AM modulation
• Data transmission applications using ASK/OOK protocols

RF Receivers Procurement Notes

Verify the specific suffix or variant (e.g., SIL) against the official RadioControlli datasheet to ensure compatibility with required power-down features and pinout standards. Confirm that the 315MHz frequency aligns with regional regulatory requirements for ISM band usage before procurement.

RF Receivers Selection Notes

Select this module when a superheterodyne design with high sensitivity (-107dBm) is required for 315MHz AM applications. Consider the SIL version if system-level power management via a dedicated power-down pin is necessary. Ensure the host system provides a stable 4.5V to 5.5V DC supply.

RF Receivers Part Context

This component belongs to the RCASK2 series of AM receiver modules from RadioControlli. It shares architectural similarities with other models like the RCASK2-434 and RCASK2-868, differing primarily in operating frequency. The series emphasizes low-cost, reliable wireless reception for industrial and consumer applications.

RF Receivers Replacement Considerations

The RCRX3-315 is a documented alternative offering similar 315MHz AM superheterodyne performance with PLL synthesis. Verify pinout compatibility and interface requirements before substitution.
