TOYO ELECTRIC MFG. CO. LTD. TY-S-433-24 用户手册
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.
