Would anyone have any idea what is missing? Hero Banned May 29, The datadheet time is usually less than 1 second when using a crystal with the specified characteristics.

LM Datasheet PDF –

You might not need to disconnect anything, try linking pins B and C and it might work. I 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 are connected to the relevant pins.

Click here to register now. So in 50 Hz land common “B” gets connected to “c” which is what you have now without the missing part. Articles Top Articles Search resources. 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.


I wouldn’t worry about it smoking. The data sheet seems to have an error when it says 60Hz pin left open is pulled down to Vdd. However, what is missing is most likely a slide switch that would have pin “b” as a common point. Welcome to our site! Mikebits Well-Known Member May 29, It would be great if I could put it to some use. Media New media New comments Search media.

Hero Banned May 28, Forums New posts Search forums. Bender New Member May 28, I suspect that there may be more missing than one might think if the distributors knew that the clock would only be sold in a area of 60 Hz. So it should work down under without the missing part. I think the TMS part looks similar as the chip that Hero identified. If your notations are correct.

LM8363 Datasheet

Sadly, you may be out of luck. May just be crazy enough to try, I did not check the lm83633 though. 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.

Anyways, in case you have trouble getting to the datssheet sheet. Bender, You’ve got that the wrong way round. I found a datasheet for a TMS I found 2 chips one on the radio and the other just behind the display of the clock.

Thanks for the heads up! When Datashheet tested the Hz going through the clock radio with a multimeter is only comes up with 50Hz Point C on the below image. In addition, the CDP features an alarm circuit thatby a transparent “freeze” circuit that assures data integrity when accessing the clock.

Thanks for all the information you have provided with regards to ddatasheet issue. Thread starter Bender Start date May 26, The manual of the radio states that it should be running at V 60Hz.

This clock regeneration may be carried out externally using a tuned circuit ln8363 internally using the on-chip Digital Clock Regenerator. Previous 1 2 Also, for 50Hz, I think you want to tie pin 26 to ground Vssnot power pin. The red line is obscuring the solder points. Digital Clock Regenerator In order to decode the incoming. IIRC, there was 2 version’s of the chip.

Potentiometer Questions Started by norbss Yesterday at As these seem to be the most common ICs it woudn’t surprise me if the clock uses eithe one or the other.
