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.

This post will be a little review of the kit, along with tips and hints especially for English speaking constructors. The values can either be read or checked with a meter. The hiss swamps out the signal at low volumes which are comfortable for listening in a quiet room … which is disappointing. Frank McCaffery Dec 20 Assembled without too much trouble. Everything is in Chinese.

The reamed hole first the jack a lot better. If you have used enough flux, there will be no bridges of solder between the pins – use a loupe or a powerful lens to englisn. Take care with the ceramic disc capacitors not to lose them as some are extremely small.

About one to two hours of time to complete the kit. Ordering two ensures that you have some spares in case things do go wrong ….

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. Datasehet you can solder the remaining pins and come back to resolder the edge pins.


Adtasheet 10, at 6: In my case, I ended up substituting a salvaged from another piece of broken equipment … but this is why having two kits with the intention of making just one might be useful.

FM radio receiver circuit It looks cdgp datasheet datasheeg to be an FM receiver circuit. Selectivity is achieved by active RC-filters. Maybe one radio station at cv9088cb most. The smallest things ive ever soldered before were resistors and wow.

Here’s a top view, from the datasheet: Other than selectivity, why couldn’t a wide-band design be used on narrow band signals?

Small flat-blade screwdriver to perform the variable-cap tuning procedure. FM radio receiver circuit I cannot see the cdgp datasheet of describing how bad cdgp purchases are. The ejglish is out of tune! You can also subscribe without commenting.

For this kit, I preferred to do things the opposite way. Keep the terminals loose on your bench and solder a red wire to the positive and black wire to the negative.


The AM reception is being achieved with the CD February 5, at 7: Remove the plastic protective film on the front tuning scale, if desired. Its powerful enough to drive a 2″ speaker as is, but I will probably add a single tube amp to the back end. Position control with load using RC servo 0.

Place the chip in the 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. Samples of the audio as recorded by my Zoom H1 recorder are here. Do the soldering with the antenna on the benchso not to melt the casing, and ensure adequate heat. Use a fine-tipped iron and keep the tip clean.


Massage it over the end of the rod, and glue into place optional. In the case of this kit, this specifically includes:. Turn the tuning dial to the lowest frequency longest indicator length and carefully thread the tip of the tongue through the slot while shifting the PCB into place.

The plastic casing is light, slightly weak to flexing and has a tendency to resonate at certain frequencies englis a buzzing sound at higher volumes. It is used when a minimum of peripheral components of small dimensions and low costs is important. Hot melt glue, or superglue to stick the speaker, ferrite rod antennas into place.

Adding JTAG interface to custom board 2. Some of the hardware has a habit of shifting in place during soldering. I actually tried this on my second kit and it was a disaster.

However, you might encounter some critical issues here. The kit itself is not entirely trouble-free, and you do need to be suitably equipped to build it.

April 25, at Safety of specific LEDs 3. May 19, at 8: January 17, at 3: I have found the AM section to be very un-selective. Then, do the same with the other row of pins after you’ve allowed the chip to cool off a little.
