The IC is a bipolar integrated circuit for use in mono portable and pocket radios.ġ. CD9088CB Datasheet, Equivalent, radio tuner. EC selectivity achieved by active RC filter, mute circuit inhibit non-IF signal and the IF signal is too weak. Small flat-blade screwdriver to perform the variable-cap tuning procedure.CD9088CB is a monolithic power FM radio tuning circuit, the external circuit is simple, low-cost applications, phase-locked loop circuit built-in frequent rate of 70kHz Department. Do not touch the antenna or you may be burnt! Use a fine-tipped iron and keep the tip clean. Getting to this stage takes about an hour. I did have problems with the jack but left it misaligned. Use the slightly enblish machine screw to secure the antenna to the rear casing. May 20, at 2: That leaves the TDAwhich is a stereo audio amplifier chip to drive speakers and headphones. Just another way engineering solves the day! In doing PCB for high frequency circuit, please make sure that you engoish components dagasheet close as possible to cdgp datasheet the lenght of the tracks as short as possible because two parallel tracks may form capacitance and as you know cdgp datasheet capacitor is frequency dependent. Will see if it works as well as yours did. The other comment about using solder paste and running the tip along the pins is one i agree with also, even if some clean up is required afterwards.
Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason. By now, most of the remaining components are resistors or capacitors. Rather unimpressively, each kit comes in a bubble wrap package. This entry was posted in AudioElectronicsRadio and tagged cheapdiyebayelectronicsmade-in-chinaprojectradiorf. Insert the ferrite rod into the end to check the fit, then glue to the rod into the holder. CD9088CB is a Monolithic Power FM radio tuning circuit, the external circuit is simple, low-cost applications, phase-locked loop circuit built-in frequent rate of 70kHz Department. Turn the tuning dial to englishh lowest frequency longest indicator length and carefully thread the tip of the tongue through the slot while shifting the PCB into place.
The values can either be read or checked with a meter. Kit Contents Rather unimpressively, each kit comes datasyeet a bubble wrap package.

Now it doesnt work.Ĭheck the orientation of the plastic holder and the PCB slot, and glue it into place so it holds the ferrite rod parallel to the Englsh. PDF DOWNLOAD CD9088CB is a monolithic power FM radio tuning circuit, the external circuit is simple, low-cost applications, phase-locked loop circuit built-in frequent rate of 70kHz Department. Magnifying glass and light to read small component values and markings also optional. De-tuning related to the IF and too weak input signals is suppressed by the mute circuit. Beginners and Experts Welcome! One time I even reduced the turns on enlish of the coils. February 5, at 7: I modified one to cover the 2 meter ham band. Having some kit-building experience helps you avoid basic mistakes like this.
Now, the screws need to be sorted and the dials installed.

Very englsih projects, hardware and software for free. Use a fine-tipped iron and keep the tip clean. The IC type is YD I tracked down a datasheet and put it on my site. The only English you will find is in the listing description, which isn’t for FM reception, with the only datasheet I could find being in Chinese. CDCB Datasheet – Monolithic electric tuning FM radio IC, CDCB datasheet, CDCB pdf, CDCB pinout, equivalent, data.
