TOYO ELECTRIC MFG TY-S-433-24 433MHz Controll Light User Manual

TOYO ELECTRIC MFG. CO., LTD. 433MHz Controll Light

User Manual

It is consisted with four sections: Ant matching net working, UHF downconverter, Resference and control， and OOK demodulator. Also shown in the figure are two capacitors (CTH C6, CAGC C4) and one timing component, usually a crystal. The Antenna matching network is coupled with four components: Z1, Z2, Z3 and Z4. With the exception of a supply decoupling capacitors(C7 and C5), and antenna impedance matching network, these are the only external components needed to assemble a complete UHF receiver. For optimal performance is highly recommended that the SYN460R is impedance matched to the antenna, the matching network will add an additional two or three components. Four control inputs are shown in the block diagram: SWEN and SHUT. Using these logic inputs, the user can control the operating mode and selectable features of the IC. These inputs are CMOS compatible, and are internally pulled-up. IF Bandpass Filter Roll-off response of the IF Filter is 5th order, while the demodulator data filter exhibits a 2nd order response.
