Product Description

CY531 Electronic Components RF receiver IC

DESCRIPTION:
The CY531 is an UHF ASK receiver IC in a small SOP-8 package which operates at 300MHz to 450MHz with typical receiving sensitivity of -109dBm.

The CY531 is a Weaver architecture receiver for ASK and OOK modulation such as pulse width modulation, variable pulse modulation, Manchester modulation and so on. The Weaver receiver also provides image rejection function to remove the image band and selects the desired signal.

The high integrated CY531 uses the low cost 8-Lead Small Outline Package (SOP-8), no extra external component is required except two capacitors (CTH and CAGC), reference crystal and antenna matching network.

The CY531 provides the Shut Down function pin (SHDN).
