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 might be the case especially near the headphone jack. Unfortunately, the instructions are only a single double-sided sheet, so the educational value of the kit is somewhat limited. For speaker used twisted pair. It seems datashset have a lacquer finish to stop the pads from oxidising, but is not otherwise tinned nor plated. Then secure this with the other identical machine screw. Start cd9088xb securing the PCB to the front of the case using a short tapping screw on the stud in-between the volume and tuning dials.
There are two kits of this same radio, type 1 and type 2. Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason. The values can either be read or checked with a meter. The next step is to align datasheeet AM band. Two AA batteries to power the receiver. I have required low power isolated DC to DC converter schematic 3. In the case of this kit, this specifically includes:.
Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio Kit
Let you know how things go. Click for more about me! Desoldering braid optional to fix mistakes. I enjoyed a lot this kit. Frank McCaffery Dec 20 Assembled without too much trouble. Massage it over the end of the rod, and glue into place optional. I might try a bit of drag soldering on an old scrap IC before dafasheet for the real thing. Just another way engineering solves the day!
Ordering two ensures that you have some spares in case things do go wrong …. You might get static, or nothing.
Its just one cap thats giving me trouble now. In the case of this kit, this specifically includes: Next, obtain the larger tuning dial and align the indentation. Very good projects, hardware and software for free.
Now, the screws need to be sorted and the dials installed. As an experienced kit builder, I wasted no time in getting started. Rather unimpressively, each kit comes in a bubble wrap package. Englisy going to grind a very fine point on a soldering iron tip before i attempt it. Beginners and Experts Welcome! Align the switch and use one of the two identical englis screws to fasten.
Some of the hardware has a habit of shifting in place during soldering. The kit itself is not entirely trouble-free, and you do need to be suitably equipped to build it.
I think it’s under KHz. The smallest things ive ever soldered before were resistors and wow. Kit Contents Rather unimpressively, each kit comes in datasyeet bubble wrap package. Small flat-blade screwdriver to perform the variable-cap tuning procedure. Continuing on, the board is completed with the population of resistors. Start alignment with the FM band. January 17, at 3: Medium sized flat-blade screwdriver to push the spring terminals into the casing. Ordering 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.
About one to two hours of time to complete the kit. I tried to clean up the solders i think i burned a bit of the pcb board. Take note of the orientation, insert, bend leads, solder and clip leads until all the electrolytics are mounted. This post will be a little review of the kit, along with tips and hints especially for English speaking constructors. FM radio cdgp datasheet circuit Thank u for the English datasheet and discussion.
That leaves the TDAwhich is a stereo audio amplifier chip to drive speakers and headphones.

FM radio receiver circuit It looks cdgp datasheet datasheeg to be an FM receiver circuit. Filtering is achieved with the external components — mainly R-C filters. Of interest is that the reception mode switch actually switches the audio path to the amplifier.
