CDCB Datasheet – Monolithic electric tuning FM radio IC, CDCB datasheet, CDCB pdf, CDCB pinout, equivalent, data. 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. The IC type is YD I tracked down a datasheet and put it on my site. Looks like a good project. Use a fine-tipped iron and keep the tip clean.

It is used when a minimum of peripheral components of small dimensions and low costs is important. Well, it took 2 months for my kit to arrive, the PCB was bowed, and some of the caps were illegible, but it worked on the first try.
I have found the AM section to be very un-selective.
CD9088CB Datasheet PDF – FORWARD
It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in. De-tuning related to the IF and too weak input signals is suppressed by the mute ejglish. Now it doesnt work. From here, we can mount the two copper air-coiled inductors.

Kit Contents Rather unimpressively, each kit comes in a bubble wrap package. Once that is soldered into place, you can breathe a sigh of relief as the worst part is over. The case for this was soon found — the components are actually wrapped inside a cellophane bag, but that sort of material has a tendency to tear when punctured by the sharp component daatsheet — quickly the smaller components work their way out. Do not fit them into the casing until they are cool, otherwise you will melt the plastic casing!
The RadioBoard Forums Forums for radio builders and experimenters. Ive little experience with fine soldering, so ill have to take my time. Sidecutters to cut cd9088b component legs. May 20, at 2: Try not to bend the leads too severely, as cracking the other protective coating can have detrimental effects on capacitor stability or performance.
Engglish the ferrite rod into the end to check the fit, then glue to the rod into the holder. Very good projects, hardware and software for free. Note the temptation to use hot-air datashest techniques.
CDCB Datasheet – Monolithic electric tuning FM radio IC
Once roughly in place, you can take the AM-FM mode switch, deburr the plastic and push it through the exterior casing over the switch. Do not touch the antenna or you may be burnt! In fact, the case even has a few curves to make it look just that little bit more stylish. If you have used enough flux, there will be no bridges englisy solder between the pins – use a loupe or a powerful lens to confirm. Then, with a molten blob of solder on your iron tip, you use it like a brush and sweep the molten blob of solder down one row of pins.
FM radio cdgp datasheet circuit Thank u for the English datasheet and discussion. Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional.
Yes you can scratch off some of that green solder mask and solder directly to the tracks enlgish you wish. For speaker used dafasheet pair. January 17, at 3: The other two battery terminals form the positive and negative. Because there were more capacitors, I decided to tackle them first.
Id like to mount this and hide it well in one of the early empty radio cabinets ive picked up. Unfortunately, the instructions are only a single double-sided sheet, so the educational value of the kit is somewhat limited.
Then you can solder the remaining pins and come back to resolder the edge pins. Beginners and Experts Welcome! November 24, at 8: That leaves the TDAwhich is a stereo audio amplifier chip to drive speakers and headphones. Before starting the assembly Datasbeet recommend you first check that no parts are missing. You can also cd9088cn without commenting. The reamed hole first the jack a lot better. Next thing was to solder a pair of yellow wires to the positive and negative of the speaker.
Think its a cute little radio for the price and works quite well with local stations both fm and am in the Winnipeg area. Small flat-blade screwdriver to perform the variable-cap tuning procedure. After the fact I saw a Russian youtube vid showing the SM chip being slickly soldered with two swipes of a soldering iron after he applied some flux from a pen dispenser. Next, get some soldering flux that comes in a syringe and use plenty englisj it all over the pins and board.
