Product Description
General Description
The CY312 is a UHF ASK receiver IC in a SOP-8 package which operates at 300MHz to 450MHz with typical receiving sensitivity of -114dBm.The CY312 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 CY312 uses the 8-Lead Small Outline Package (SOP-8), also no extra external component is required except one capacitor (CTH), reference crystal and antenna matching network.
The CY312 additionally provides the Shut Down function pin (SHDN) and CTH pin, the CTH with different external capacitor can satisfy various data profile.
