Hi!
Has anyone completed any tests at the pad for the Audio PLL1/2 in the i.MX8?
Are there any data on the performance characteristic of these two PLLs at 19.2Mhz output.
Phase Noise at 10 Hz ?? dBc/Hz
Phase Noise at 1 kHz ?? dBc/Hz
Phase Noise at 10 kHz ?? dBc/Hz
Phase Noise at 100 kHz ?? dBc/Hz
The Toshiba LDO TCR3RM18A has superb PSSR in the audio band compared to LDOs found in the PCA9450
Would it benefit the audio related PLLs to be powered separately close the relevant VDD_ pads?
Or a are all PLL VDD internally connected?
