SN74LV4046A: PLL Jitter issue

Erik Jones

Part Number: SN74LV4046A

New to using a PLL, but have a circuit that converts 30Hz square wave to 12.288 MHz

We have fine-tuned the circuit, but still have 20-40uS jitter between reference (SIN) and CIN.

Ideas to reduce jitter? Better clock gen IC options?

Hi Erik,
We don't have clocking devices capable of producing 12.288 MHz output with a 30 Hz input.

Would you be willing to use a different input frequency?

What output frequency type does your application require?

Regards,

Vicente
