Hi all, we use i.MX6 for audio application. i.MX6 generate master clock for bit rate like 44.1 for audio cd quality.
We use PLL4 (also referred to as an Audio PLL) - This is a fractional multiplier PLL used
for generating a low jitter and high precision audio clock with standardized audio
frequencies. The PLLs oscillator frequency range is from 650MHz to 1300MHz, and
the frequency resolution is better than 1Hz. This clock is mainly used as a clock for
serial audio interfaces and as a reference clock for external audio codecs. It is
equipped with a divider on its output and can generate divided by 1, 2 or 4 from the
PLL VCO frequency.
Question we have a low jitter, but we want to quantify this value (nano sec , pico sec) ?
