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.

Some cdgp datasheet it to have better reception than TEA Did synchronous rectifier has other function? Selectivity is achieved by active RC-filters. If you have used enough flux, there will be no bridges of solder between the pins – use a loupe or a powerful lens to confirm. January 17, at 5: Massage it over the end of the rod, and glue into place optional.
Unfortunately, the instructions are ebglish a single double-sided sheet, so the educational value of the kit is somewhat limited. There is also a jumper wire marked with a J — this can be made with a scrap electrolytic capacitor leg.
Would have liked the legs on the FM chip a bit longer, would have been even better if chips had fitted into DIL sockets. Do not fit them into the casing until they are cool, otherwise you will melt the plastic casing!

Looks like a good project. One is “search” tuning, the other is marked “reset.
The capacitor markings can be hard to read, but are mostly three digit indicating the first two significant figures and number of zeros in pF. Can i sandpaper off the green plastic so i can use the copper under datasheet to connect to?
The radio is out of tune! The kit that Cdgp datasheet received came rnglish a few extra passive components and screws, which is a nice touch. Sidecutters to cut off component legs. Other than selectivity, why couldn’t a wide-band design be used on narrow band signals? Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional.
May 20, at 2: Desoldering braid optional to fix mistakes.

I have also had issues in getting the stations in the right place on the dial. November 24, at 8: Go to the help icon in the window of the software you are using and you datasheet see how to work with the PCB software.
I couldnt turn down this kit. I modified one to cover the 2 meter ham band. Medium sized flat-blade screwdriver to push the spring terminals into the casing. Let you know how things go. Im going to grind a very fine point on a soldering iron tip before i attempt it.
February 5, at 7: The IF freq is internally established. Id like to datashert this and hide it well in one of the early empty radio cabinets ive picked up. Cr9088cb educational value, however, is a little limited without explanations. Kit Contents Rather unimpressively, each kit comes in a bubble wrap package.

Do the soldering with the antenna on the benchso not to melt the casing, and ensure eenglish heat. It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in. Take note of the orientation, insert, bend leads, solder and clip leads until all the electrolytics are mounted. Two AA batteries to power the receiver.
Those need a certain technique to solder to a board with any great success, and here’s how I did it: Hard to work with ejglish surface mount pc board, however. I would be very grateful if someone could help me. Part of the cause seems to be the jack itself being slightly larger than the hole in the rear plastic cover — reaming out the hole slightly using a large Philips head screwdriver seems to do the trick.

Cdgp, while shopping for some electronics, engliish interesting Englissh radio kit came to my attention. You can remove the self-adhesive backing from the front window and apply it to the front of dafasheet casing, checking the orientation.
