CD9088CB DATASHEET ENGLISH PDF

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.

Getting to this stage takes about an hour.

Repeat for the UTC as well. I made do with my Weller iron but it was a challenge. Looks like a good project. The educational value, however, is a little limited without explanations. Datashewt 23, at 9: Position control with load using RC servo 0.

The hiss swamps out the signal at low volumes which are comfortable for listening in a quiet room … which is disappointing. The next step is to align the AM band.

Small flat-blade screwdriver to perform the variable-cap tuning procedure. Ordering two ensures that you have some spares in case things do go wrong … This post will be a dataseet review of the kit, along with tips and hints especially for English speaking constructors.

Rather unimpressively, each kit comes in a bubble wrap package. It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in. Trouble was already spotted when dataaheet loose screw was seen rattling inside the bubble wrap — the components have broken loose and the only thing preventing them from going everywhere was a thin and somewhat torn bubble wrap.

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. Once that is soldered into place, you can breathe a sigh of relief as the worst part is over. Take the time to align the IC in the correct position and solder opposing pins. It is a very small surface mount chip.

Will see if it works as well as yours did. This goes in one direction at the end of the battery compartment and needs to be slid into place in its rails.

Turn the tuning dial to a known station location, and if you have a second radio, have it playing the same station. Another radio that is in tune to verify received stations also recommended, but not absolutely necessary.

We start by first emptying all components into a plastic bowl so they can be sorted through. In the case of this kit, this specifically includes: Take care with the englisj disc capacitors not to lose them as some are extremely small. Its just one cap thats giving me trouble now. Bench-top supply with crocodile clips, 3V output to power receiver during tuning recommended, but not absolutely necessary.

Frank McCaffery Dec 20 Assembled without too much trouble. Part of the cause seems to be the jack itself satasheet 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. You can get a complete scanning FM radio, with headphones, for a buck. Next, try to close the case hooking over the headphone out jack first, and then clipping in the tuning dial side.

Clean up all the excess flux when you’re done. It might become my new shop radio. Start alignment with the FM band. I was aware of the Tecsun 2P3 which looks to be a very nice kit, but a bit on the pricey side for an AM only radio. Preparation We start by first emptying all components into a plastic bowl so they can be sorted through.

I actually tried this on my second kit and it was a disaster. EDIT, its now all soldered up, sans the tiny ic chip. 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. Enlgish 20, at 2: Hopefully if they forget to include the data sheets, I can print out yours. I tried to clean up the solders i think i burned a bit of the pcb board. I think it’s under KHz. On one of the two samples, it can occasionally during a signal dip end up getting pulled into an adjacent station over time.

For this kit, I preferred to do things the opposite way. You can remove the self-adhesive backing from the front window and apply it to the front of the casing, checking the orientation. Keep the terminals loose on your bench and solder a red wire to the positive and black wire to the negative. Lead the yellow wire to the ANT terminal and tack solder. Because if i screw it up, looks like this thing if junk then.

You might get static, or nothing. I agree about the SMD Hot air re-flowing. Place the chip in cd9088ch exact position you want it in, and tack-solder two of the pins to the board, top left – and bottom right, so it cannot skew on the board. Instead, you will have to solder the yellow wire to the arm next to the screw hole, making sure the solder is low profile not to interfere with fitting the antenna through cd9088cv slot. In fact, the case even has a few curves to make it look just that little bit more stylish.
