CD4046B: Looking for low frequency PLL intergrated circuit

Michael Borza

Part Number: CD4046B

Tool/software:

I am looking for a PLL integrated circuit with a VCO able to cover the 15 - 25 kHz range.

Would the CD4046 work for such a low range?

Thank you,

Michael

Hi Michael,

Given this is a very old part, we don't have experience on it. According to the datasheet, it should support these frequencies range.

Could you please recommend something else?

The PLL is intended to keep a system running at resonance in the 15 -25 kHz range. Resonance is assessed by a phase detector.

Hi Michael,

I don't have any recommendation, you know, this is kind of a legacy product, there is no newer generation.
