The SYN531R 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 SYN531R 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 SYN531R 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 SYN531R provides the Shut Down function pin
(SHDN)
