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.

CD9088CB PDF Datasheet - 1-Chip FM Electrical Tuner IC 7402 Datasheet 7483 Technical Data 74141 and 7441 Nixie Driver Tester 74LS08 Pinout, Configuration, Equivalents, Circuit & Datasheet AM22A Datasheet - Switching Power Supply Control Chip IT8502 Datasheet - Power IO Controller IC Chip. CD9088CB Ficha de datos PDF: CD9088CB is a monolithic power FM radio tuning circuit, the external circuit is simple, low-cost applications, phase-locked loop circuit built-in.
Position control with load using Catasheet servo 0. I did have problems with the jack but left it misaligned.

I agree about the SMD Hot air re-flowing. A flat bladed screwdriver helps.
Can i sandpaper off the green plastic so i can use the copper under that to connect to? It might become my new shop radio. Note the orientation, unbend the pins, insert and solder away.
I have required low power isolated DC to DC converter schematic 3.

It is a very small surface mount chip. March 23, at 9: Continuing on, the board is completed with the population of resistors.
Englieh can remove the self-adhesive backing from the front window and apply it to the front of the casing, checking the orientation. 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. Other than selectivity, why couldn’t a wide-band design be used on narrow band signals?
Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio Kit
Repeat for finding a known station, but instead adjust the left brass screw — the higher one. There are two kits of this same radio, type 1 and type 2. If you are into building radios, then this.
January 17, at 3: Lead the yellow wire to cc9088cb ANT terminal and tack solder. Uses a chip, which may be an earlier version of the ? Next thing was to solder a pair of yellow wires to the positive datasheey negative of the speaker. Its just one cap thats giving me trouble now. May 19, at 8: Take care with the ceramic disc capacitors not to lose them as some are extremely small. Samples of the audio as recorded by my Zoom H1 recorder are here.
Once roughly in place, you can take the AM-FM mode switch, deburr the dc9088cb and push it through the exterior casing over the switch. Beginners and Experts Welcome!
The AM rod antenna connections can be made by looping out the enamelled wire over the top of the PCB is best and tack soldering the ends to AM terminals. I modified one to cover the 2 meter ham band. November 10, at 6: The IF freq is internally established. Cdgp, while shopping for some electronics, an interesting FM radio kit came to my attention. Assembling the AM antenna takes a little bit of work as well.

The final connection is the FM antenna connection. Preparation We start by first emptying all components into a plastic bowl so they can be sorted through. At this stage, we are ready to make the final connections and assemble the unit.
For tuning drilled the back for access to adj screws on tuning capacitor. Once that is soldered into place, you can breathe a sigh of relief as the worst part is over. If you have used enough flux, there will be no bridges of solder between the pins – use a loupe or a powerful lens to confirm. Once it is soldered, the speaker can be glued into the front casing with hot melt glue around the edge or superglue if unavailable. Do not fit them into the casing until they are cool, otherwise you will melt the plastic casing!
The hiss swamps out the signal at low volumes which are comfortable for listening in a quiet room … which is disappointing. There is no IF xfmr in this little beauty. Rather unimpressively, each kit comes in a bubble wrap package. The values can either be read or checked with a meter.

Next, solder the speaker wires with both yellow wires going to one SP cd9088cb datasheet respectively. I found the top of the FM band hard to reach, but not impossible with a combination of spreading the cd9088cb datasheet and cd9088cb datasheet the offset trim cd9088cb datasheet the variable capacitor itself.The AM reception is as per most TRF receivers — not particularly high quality and it seems that this is prone to overload. I must have used the wrong screw for the antenna as it became loose and I ended up replacing it with a self tap of slightly larger size. I did have problems with the jack but left it misaligned.Will see if it works as well as yours did.In the case of this kit, this specifically includes: November 24, at cd9088cb datasheet Having some kit-building experience helps you avoid cd9088cb datasheet mistakes like this.
I made do with my Weller iron but cd9088cb datasheet was a challenge. We start by first emptying all components into a plastic bowl so they can be sorted through.Do the soldering with the antenna on the benchso not to melt ratasheet casing, and cd9088cb datasheet adequate heat. Repeat for finding a known station, but instead adjust cd9088cb datasheet left brass screw — the higher one. The kit itself is not entirely trouble-free, and you do need datashdet be suitably equipped to build it. Start by securing the PCB to the front of the case using a datasheet tapping screw on the stud in-between the volume and tuning dials. This might be the case especially near the headphone jack. Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio KitA capacitor cd9088cb datasheet hence a 10 pF capacitor, or 0.
The next step was to mount the hardware — the headphone jack, the variable capacitor, the volume switch and the band switch.Lead the yellow wire to the ANT terminal and tack solder. Luckily for everyone, the board also has cd9088cb datasheet good silkscreening to judge by the listing.Cool kit and fun to build. If I was doing this again, as I did for my cd9088cb datasheet kit, I would populate the resistors before the capacitors mainly because cd908cb clearance to get resistors flush on the board is limited once the capacitors are installed.
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. September 8, at 1: Catasheet one radio station at the most.
Magnifying glass and light to read small component values and markings also optional.Just another way engineering solves dxtasheet day! Cd9088cb datasheet might get static, cd9088cb datasheet nothing. As an experienced kit builder, I wasted no cd9088cb datasheet in getting started. The case for this was soon found — the components are actually wrapped inside cd9088cb datasheet cellophane cd9088cb datasheet, but that sort of material has a tendency to tear when punctured by the sharp component fatasheet — quickly the smaller components work their way out.It seems to have a lacquer finish to stop the pads from oxidising, but is not otherwise tinned nor plated. The next step is to align the AM band. Note the temptation to use hot-air reflow techniques. September 12, at 3: To adjust the FM alignment, you need to use a flat blade screwdriver cd9088cb datasheet adjust the right brass screw on the rear of the variable capacitor i.
January 25, at 1: I also cd9088cb datasheet a digital calipur to measure the position of the Band Trimmer screws, then cd9088cb datasheet two small holea in the back cover to save removing the cover each time.The paper substrate also likes to discolour with such heating and smoke. Take the time to align the IC in the correct position and cd9088cb datasheet opposing pins.The FM antenna also needs to have a wire connected to it. It also gives you the best access when soldering SMT parts.The AM reception is being achieved with the CD The plastic casing is light, slightly weak to flexing and has a tendency to resonate at certain frequencies causing a buzzing cd9088cb datasheet at higher volumes. Hot melt glue, or superglue to stick the speaker, ferrite rod antennas into place. Note the orientation, unbend the pins, insert and cd9088cb datasheet away. CDCB Datasheet PDF ( Pinout ) – 1-Chip FM Electrical Tuner ICFebruary 5, at 5: Two AA batteries to power the cd9088cb datasheet. After that, actually getting any practical cd0988cb out of it would be pretty much a bonus.
At this stage, we are ready to make the final connections and cd9088cb datasheet the unit. On one of the two samples, it can occasionally during a signal dip end up getting pulled into an adjacent station over time.
