I’m assuming now all I need now is short the power to pin 25 or 26 and test it out.

I cannot remember the IC id most of those old clock radio’s used. Activating VSS using two inputs simultaneously alarm select and sleep selectthe. 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.

On the back of the clock radio there is a place where it looks like a switch should be to allow me to change between 50 and 60 Hz. Also, for 50Hz, I think you want to tie pin 26 to ground Vssnot power pin. Mikebits Well-Known Member May 29, This clock regeneration may be carried out externally using a tuned circuit or internally using the on-chip Digital Clock Regenerator.

The switch on the side adjusts the clock radios brightness and also set the time. Articles Top Articles Search resources. Potentiometer Questions Started by norbss Yesterday at It would be great if I could put it to some use. The red line is obscuring the solder points. That’s why I’m wondering if your notations are correct. This digital clock regenerator circuit continuously re-synchronises a divide-by-8 counter beingcircuit or internally using the on-chip digital clock regenerator.


IIRC, there was 2 version’s of the chip. The has 28 pins. In addition, the CDP features an alarm circuit thatby a transparent “freeze” circuit that assures data integrity when accessing the clock. Therefore, a requirement when using. LM with led clock Abstract: For a better experience, please enable JavaScript in your browser before proceeding.

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”. Upon opening the baby up and taking a quick look around it would appear that there is something missing on datzsheet PCB board that should link point A and Point B to convert the 50Hz to 60Hz. Is it possible you miscounted the pins? Clock Accuracy Whentimeout mechanism.

To participate you need to register. Hi All Apart from doing some basic electrical work back in high school 13 years ago it would be safe to say that I have lost some skills and require some assistance.

I have a feeling if I can get the specs for this guy I will be able datasueet move forward. I wouldn’t worry about it smoking. The manual of datsaheet radio states that it should be running at V 60Hz. No abstract text available Text: I found 2 chips one on the radio and the other just behind the display of the clock. A “1” in bit-7 will identify the alarm circuit.

LM8363 View Datasheet(PDF) – SANYO -> Panasonic

I went ahead and checked the pinout. Electro Tech is an online community with ml8363members who enjoy talking about and building electronic circuits, projects and gadgets.


Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I would suggest that you don’t mess around datwsheet shorting any of the IC pins, just connect pins B and C on the PCB, which are connected to the relevant pins.

What clock IC does it use? Sadly, you may be out of luck.

Yep I did miss count, I hadn’t had my morning coffee yet By using the status register 2, users can select either of; alarmclock data speed, in the wide range, which is caused by the oscillation circuit ‘s frequency deviationcontroller 1 VDDL Alarm expansion register 1 INT register 1 Clock correction register FOUT.

Each alarm has its own alarm output signal. Or tell me what I need to buy to make it run at 60Hz? Pad “c” seems to go nowhere. B is connected to many other points.

LM8363 Datasheet

Digital Clock Regenerator In order to decode the incoming. Started by fastline Yesterday at 8: If your notations are correct. 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 Datxsheet america.
