CDCB datasheet, CDCB PDF, CDCB Pinout, CDCB Equivalent, CDCB Replacement – Monolithic Power FM radio tuning circuit. 14 Sep 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.

I modified one to cover the 2 meter ham band.
There is cd9088cb datasheet english IF xfmr in this little beauty. Use the slightly different machine screw to secure the antenna to the dtaasheet casing. Note the orientation, unbend the pins, insert and solder away.
The AM reception is as per most TRF receivers — not particularly high cd90888cb and it seems that this is prone to overload. This really is a kit that looks almost store bought! I must have used the wrong screw for the antenna as it cd9088cb datasheet english loose and I ended up replacing it with a self tap of slightly larger size.
Because there were more capacitors, I decided to tackle them first.

Massage it over the end of the rod, and glue into place optional. Magnifying glass and light to read small component values and markings also optional. I agree about the SMD Hot air re-flowing. One is “search” tuning, the other is marked “reset. Once cd9088cb datasheet english in place, you can take the AM-FM mode switch, deburr the plastic and cd9088cb datasheet english it through the exterior casing over the switch.
Maybe one radio station at the most. March 23, at Plus, i do need to hone my skills on finer soldering.
November 24, at 8: I suppose I could disable the scan and just use a very small variable cap. Start cd9088cb datasheet english with the FM band. Datasheey 10, cd9088cb datasheet english 3: I have found the AM section to be very un-selective.
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.

Lead the yellow wire to the ANT terminal and tack solder. Now, the screws need cd9088cb datasheet english be sorted and the dials installed. It is a very small surface mount chip. Cd9088cb datasheet english capacitor is hence a 10 pF capacitor, or 0. January 17, at 3: Its powerful enough to drive a 2″ speaker as englihs, but I will probably add a single tube amp to the back end. Because if i screw it up, looks like this thing if junk dattasheet.

I might try a bit of drag soldering on an old scrap IC before going for the cd9088cb datasheet english thing. Trouble was already spotted when a loose screw was seen rattling inside the bubble wrap — the components have broken loose and the only thing preventing them from going everywhere was a thin and somewhat torn bubble wrap. It seems to have a lacquer finish to stop the pads from oxidising, but is not otherwise tinned nor plated.
June 15, at Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional. Sound quality cd9088cb datasheet english good. Ordering two ensures that you cd908cb some spares in case things do go wrong …. Im going to grind a very fine point on cd9088cb datasheet english soldering iron tip before i attempt it.

Repeat for finding a known station, but instead adjust the left brass screw — the higher one. You might get static, or nothing. Instead, you will have to solder the yellow wire to the arm next to the screw hole, making sure the solder is low profile not to interfere with cd9088cb datasheet english the antenna through the slot.
