Digital Clock Regenerator In order to decode the incoming. Just saying hello Started by MichaelaJoy Yesterday at 6: The switch on the side adjusts the clock radios brightness and also set the time.

For instance all of north america is 60 but south america has both 50 and 60 Hz dependent on country and most of the rest of the world is 50hz. Sadly, you may be out of luck. You must log in or register to reply here. It would be great if I could put it to some use. A “1” in bit-7 will identify the alarm circuit. Forums New posts Search forums.

I found a datasheet for a TMS I cannot remember the IC id most of those old clock radio’s used. Hero Banned May 30, Thanks for all the information you have provided with regards to my issue. 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. 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. So it should work down under without the missing part.

Bender, You’ve got that the wrong way round. The fixed-cycle timer source clock is specified using the TSS1 and TSS0 Timerfrom the falling edge of the clock after writing to Address 0Dh, as shown in the following diagramThe alarm interrupt function generates an interrupt when the clock matches the time setting in the.

Here is the pinouts. This clock regeneration may be carried out externally using a tuned circuit or internally using the on-chip Digital Clock Regenerator. I think you should leave pin 25 alone. May just be crazy enough to try, I did not check the pincount though. The has 28 pins. Hero Banned May 28, Here is the back of the PCB, sorry for the low res image, I took it from my mobile phone. This digital clock regenerator circuit continuously re-synchronises a divide-by-8 counter beingcircuit or internally using the on-chip digital clock regenerator.

Anyways, in case you have trouble getting to the data sheet. B is connected to many other points. Or tell me what I need to buy to make it run at 60Hz? LMLM Try Findchips PRO for clock alarm circuit diagram using lm Clock Accuracy Whentimeout mechanism.

Welcome to our site! What clock IC does it use?

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 to convert the 50Hz to 60Hz. In 60 Hz land “b” gets connected to “a” which would go out datazheet the ribbon cable to somewhere an adapt the counters to accommodate the change in frequency which they use to set the time base.

As these seem to be the most common ICs it woudn’t surprise me if the clock uses eithe one or the other. I then purchased a step down converter so it would work and it does just fine however the time is out by 10 seconds. The red line is obscuring the solder points. Activating VSS using two inputs simultaneously alarm select and sleep selectthe. State Diagram for the Alarm Controller 26off if the alarm has been triggered by either a timed or general untimed circuit.
