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.

All cdgp datasheet joints should have a shiny finish! Another radio that is in tune to verify received stations also recommended, but not absolutely necessary. EDIT, its now all soldered up, sans the tiny ic chip. Kit Contents Rather unimpressively, each kit comes in a bubble enhlish package.


I would be very grateful if someone could help me. Insert your two AA batteries of choice, and you engllish start listening to radio right away. There is also a jumper wire marked with a J — this can be made with a scrap electrolytic capacitor leg. The schematic as listed is shown above. Frank McCaffery Dec 20 Assembled without too much trouble.

Lead the yellow wire to the ANT terminal and tack solder. Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason.

Peeking inside a dztasheet is one of top things cdgp datasheet sparks the interest of many young people in electronics!

Rather nicely, the PCB is a single sided paper-type board with silkscreening on both sides which is very descriptive, and solder mask on the rear. By now, most of the remaining components are resistors or capacitors. November 10, at 6: Datashedt sized flat-blade screwdriver to push the spring terminals into the casing. Trouble was already spotted when a loose screw was seen rattling cv9088cb the bubble wrap cd9088c the components have broken loose and the only thing preventing them from going everywhere was a thin and somewhat torn bubble wrap.

It might become my new shop radio. Then, do the same with the other row of pins after you’ve allowed the chip to cool off a little. Looks like a good project. Next, get some soldering flux that comes in a syringe and use plenty of it all over the pins and board.

Its just one cap thats giving me trouble now. Datashedt, it took 2 months for my kit to arrive, the PCB was bowed, and some of the caps were illegible, but it worked on the first try. Some cdgp datasheet it to have better reception than TEA Did synchronous rectifier has other function?

Samples of the audio as recorded by my Zoom H1 recorder are here. Start by securing the PCB to the front of the case using a short tapping screw on the stud in-between the volume and tuning dials. I have achieved everything, except the connections of the AA Batteries.

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.


The FM antenna also needs to have a wire connected to it. I will definitely have to use my halogen desk lamp to help me see this as i work.

The IF freq is internally established.

Assembling the AM antenna takes a little bit of work as well. I couldnt turn down this kit. The plastic casing is light, slightly weak to flexing and has a tendency to resonate at certain frequencies causing a buzzing sound at higher volumes. Arduinos nano wireless sensor network 3.

Before starting the assembly I recommend you first check that no parts are missing. Think its a cute little radio for the price and works quite well with local englihs both fm and am in the Winnipeg area. If I was doing this again, as I did for my second kit, I would populate the resistors before the capacitors mainly because the clearance to get resistors flush on the board is limited once the capacitors are installed.

This really is a kit that looks almost store bought! Hopefully if they forget to include the data sheets, I can print out yours. I wonder if adding some holes in the back of the case would help.
