Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at CD, To Divide by Home – IC Supply – Link. You must log in or register to reply here. There will be some jitter, but for a timekeeping purpose, it is usually of no consequence.
If I’m reading Fig 1 of the ‘ datasheet correctly, I think it goes like this: TI does not warrant or represent. Thread starter chemelec Start date Jan 20, Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at There is a project I did which got published on Silicon Chip magazine, which describes how to exactly obtain 50 or 60 Hz and its 2nd harmonic in the instance that you are driving a common alarm clock derived from a watch crystal and utilizing the CD assisted by a small 8 pin micro.

Potentiometer Questions Started by norbss Yesterday at Welcome to our site! If you already have the kHz crystal on hand, and c4d059 satisfied with the output frequency not being exactly 60 Hz, that’s fine, but there are other crystal frequencies available that can be divided down exactly to 60 Hz.
No, That was an older chip.
