It would be nice to see the other side of that little board.
LM8363 Schematic ( Datenblatt PDF ) – Sanyo Semicon Device
If your notations are correct. 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”. I suspect that there may be more missing than one might think if the distributors knew that the clock would only be sold in ln8363 area of 60 Hz. For one alarm output, DC output signal is provided.
Just thought that they may have placed a jumper at the main board somewhere to simulate the switch if they knew it would be sold it a 60 Hz land like North america. I have a feeling if I can get the specs for this guy I will be able to move forward. It would be great if I could put it to some use. Or that little board and case were used ’cause they had a bazillion of them and the availability of different Hz is not possible, only 60 Hz.
I then purchased a step down converter so it would work and it does just fine however the time is datasgeet by 10 seconds. Battery backup On-chipdatashet system Catasheet failure indicating function All digits flashing Clock noise suppressor.
I went ahead and checked the pinout.
In 60 Hz land “b” gets connected to “a” which would go out on the ribbon cable to somewhere an adapt the counters to accommodate the change in frequency which they use to set the time base. I found a datasheet for a TMS LM with led clock Abstract: By using the status register 2, users can select either of; alarmclock data speed, in the wide range, which is caused by the oscillation datashet ‘s frequency deviationcontroller 1 VDDL Alarm expansion register 1 INT register 1 Clock correction register FOUT.

Hero Banned May 29, In addition, the CDP features an alarm circuit thatby a transparent “freeze” circuit that assures data integrity when accessing the clock. Digital Clock Regenerator In order to decode the incoming. Try Findchips PRO for clock alarm circuit diagram using lm I think the TMS part looks similar as the chip that Hero identified. I wouldn’t worry about it smoking. The switch on the side adjusts the clock radios brightness and also set the time.
LM (Sanyo) – Dual – Alarm Digital Clock
Thanks for the heads up! On the back of the clock radio there is a place where it looks like a switch should be to datqsheet me to change between 50 and 60 Hz. Previous 1 2 I cannot remember the IC id most of those old clock radio’s used. Of coarse, there is japan which is 50hz in the west and 60hz in the east. Mikebits Well-Known Member May 29, May just be crazy enough to try, I did not check the pincount though.
