Try Findchips PRO for clock alarm circuit diagram using lm I have a feeling if I can get the specs for this guy I will be able to move forward.

Missing Components on a Clock Radio

So in 50 Hz land common “B” gets connected to “c” which is what you have now without the missing part. It appears that the black ribbon cable is 4 wires and there are 5 points, one of which is your red trace line from “a”. IIRC, there was 2 version’s of the chip. I went ahead and checked the pinout. Forums New posts Search forums. You might not need to disconnect anything, try linking pins B and C and it might work.


Therefore, a requirement when using. As these seem to be the most common ICs it woudn’t surprise me if the clock uses eithe one or the other. Of coarse, there is japan which is pm8363 in the west and 60hz in the east.

Valid only when using the alarm functionSupply Voltage Detection Circuit “. I found 2 chips one on the radio and the other just behind the display of the clock.

Also, for 50Hz, I think you want to tie pin 26 to datasheeet Vssnot power pin. Started by fastline Yesterday at 8: May just be crazy enough to try, I did not check the pincount though. Thread starter Bender Start date May 26, To participate you need to register. Would anyone have datssheet idea what is missing?

This clock regeneration may be carried out externally using a tuned circuit or internally using the on-chip Digital Clock Regenerator. I wouldn’t worry about it smoking. Thanks for all the information you have provided with regards to datsaheet issue.

LM8363 Schematic ( Datenblatt PDF ) – Sanyo Semicon Device

I found a datasheet for a TMS Upon opening the baby up and taking a quick look around it would appear that there is something missing on the PCB board that should link point A and Point B datasheeh convert the 50Hz to 60Hz. Media New media New comments Search media.


So it should work down under without the missing part. Here is the back of the PCB, sorry for the low res image, I took it from my mobile phone. I think the TMS part looks similar as the chip that Hero identified.

(Datasheet) LM pdf – Dual – Alarm Digital Clock (1-page)

LM with led clock Abstract: Each alarm has its own alarm output signal. No abstract text available Text: For one alarm output, DC output signal is provided. I got a soldering iron coming on Monday so I will post back and let you know how I go. Hero Banned May 29, The has 28 pins. Yep I did miss count, I hadn’t had my morning coffee yet Datasneet would suggest that you don’t mess around with shorting any of the IC pins, just connect pins B and C on the PCB, which datwsheet connected to the relevant pins.
