Introduction

SY531R is a next-generation, low-power, high-performance, plug-and-play OOK RF receiver requiring no register configuration, suitable for wireless reception applications in the 300–480 MHz ISM band. The SY531R supports data rates of 1–5 kbps, making it ideal for pairing with low-cost encoder- or MCU-based transmitters. The device operates over a supply voltage range of 2.1–5.5 V, within which receive performance remains largely unaffected by supply voltage variation. Operating at 433.92 MHz, the device achieves a receive sensitivity of –110 dBm at a supply current of only 5.3 mA. By selecting crystals of different frequencies, the device can operate at the commonly used 315 MHz frequency or other RF frequencies within the applicable band.
