PLL that received 40 KHz as reference oscillator

Does anyone knows where can I find such pll?

Which companies are known best for their PLL designs?

Thank you.

The 56x series of one chip PLL circuits are made by several companies.

X is a number. For instance 567.
http://www.exar.com/products/XR2212v201.pdf is one example data sheet.

You can use NE567. it is for low frequency application.

best regards

Can you be more specific? what is the part number? or full name of the series..

I searched google for 56X and all he gaved me was CD-ROM series.

What companies are manufactoring such series?

Thanks again..

Thank you all.

Do you know about a PLL that the OSCin (reference oscillators) is in the range of

40 KHz and the Output is in the range of up to 100 MHz?

Best regards.
