Hi Team,
My Customer wanted to know which equation for Frequency Capture Range (2Fc) is correct or why the datasheet vs application note equation is different? From the datasheet of CD4046B (page 3-125) equation for 2fc is having a multiplier of 1/pi, unfortuanately application note states that the equation is the same except that the multiplier is 1/(tau1) (on page 15).

Looking forward to your reply.
Best regards,
Renan Adriano
