CDCB Datasheet PDF ( Pinout ) – Monolithic Power FM radio tuning circuitĪs mentioned, the instructions were all in Chinese. The best rule of thumb when assembling circuit boards is to start with the lowest height components and progress to the tallest ones. Preparation We start by first emptying all components into a plastic bowl so they can be sorted through. The radio is out of datasheer The schematic as listed is shown above.įebruary 5, at 5: Rather nicely, the PCB is a single sided paper-type board with silkscreening on cr9088cb sides which is very descriptive, and solder mask on the rear. The values can either be read or checked with a meter. The educational value, however, is a little limited without explanations. April 25, at Then solder each successive pin taking care not to short out adjacent pins.
September 8, at 1: Part of the cause seems to be the jack itself being slightly larger than the hole in the rear plastic datashet - reaming out the hole slightly using a large Philips head screwdriver seems to do the trick. Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio Kit Sounds like a demented wasp trying to escape a Coca-Cola can.
Repeat for finding a known station, but instead adjust the left brass screw - the higher one.
Then you can solder the remaining pins and come back to resolder the edge pins.Īssembling the AM antenna takes a little bit of work as well. Small flat-blade screwdriver to perform the variable-cap tuning procedure. For this, stick the wire through the slot in the rear of the casing, and the screw hole end of cd9088bc antenna through the slot. It also gives you the best access when soldering SMT parts. The CD is responsible for FM reception, with the only datasheet I could find being in Chinese.

This really is a kit that looks almost store bought! Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional.CDCB ETC datasheet pdf data sheet FREE Datasheets (data sheet) search for integrated circuits (ic), semiconductors and other electronic components. Having some kit-building experience helps you avoid basic mistakes like this. Conclusion After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit. Do the soldering with the antenna on the benchso not to melt the casing, and ensure adequate heat. I have found the AM section to be very un-selective.įor tuning drilled the back for access to adj screws on tuning capacitor. Try not to bend the leads too severely, as cracking the other protective coating can have detrimental effects on capacitor stability or performance. As mentioned, the instructions were all in Chinese. It also gives you the best access datasheey soldering SMT parts. Turn fatasheet 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. At this stage, we are ready to make the final connections and assemble the unit. Otherwise, the IC may not be soldered in the right orientation, or the switch may have been damaged. Datashfet two ensures that you have some spares in case things do go wrong … This post will be a little review of the kit, along with tips and hints especially for English speaking constructors. Once it is soldered, the speaker can be glued into the front casing with hot melt glue around the edge or superglue if unavailable. catasheetĬlick for more about me! March 23, at Note the orientation, unbend the pins, insert and solder away. I have also had issues in getting the stations in the right place on the dial. The other two battery terminals form the positive and negative.įrank McCaffery Dec 20 Assembled without too much trouble. The best rule of thumb when assembling circuit boards is to start with the datasheeg height components and progress to the tallest ones.
