FM Radio Receiver Display Module Frequency Modulation Stereo Receiving LCD Display SC3610 / Frequency Display Screen

Note: This module is suitable for radios or nsmitters with local oscillator circuits. It is not suitable for DSP radios without local oscillator circuits!This module adopts SC3610D drive, working voltage: 1.8-3.3V, this module currently only supports frequency display, does not support clock function, frequency display range: AM: 0.5-30MHZ,Intermediate frequency 455KHZ;FM: 11-150MHZ, for FM, optional intermediate frequency 10.7MHZ (disconnect IFsel) and 70KHZ (short connection IFsel)The module dimensions are 25X24X5mm.Description of each pin function:1, + pad, power supply, can not exceed 3.3V, otherwise it may out the module.2, - pad, power supply is negative.3. Fin pad, external oscillation signal input pin, the board has its own measured signal input coupling , no need to connect externally. When used for nsmitter frequency display, it is usually connected to the local oscillator output or secondary amplification output of the nsmitter. At this time, short-circuit IF, select intermediate frequency 70KHZ, and whether AF and RG are short-circuited depending on actual needs. The displayed frequency has an error of about 0.1MHZ with the actual nsmiion frequency; when used for radio frequency display, it is usually connected to the local oscillator output of the radio or the AFC pin, and the display frequency is accurate.4. AF jumper, AM/FM selection, short-circuit---The module works in FM display mode, disconnected---The module works in AM display mode.5, RG jumper, when working in FM mode, short RG, display frequency range: 11-150MHZ; disconnect RG, display frequency range: 11-99.99MHZ. When working in AM mode, short-circuit RG, display frequency range: 0.5MHZ-29.99MHZ, disconnect RG, display frequency range: 500KHZ-9999KHZ.6, IF jumper, FM IF selection, short---- for FM IF 70KHZ (such as TDA7021, TDA7088, etc.), disconnected - for FM IF 10.7MHZ (such as CXA1691, CXA1238, etc.).
