**Part Number:** LMK03318

Hi,

The LMK03318 manual states figures for rejection of noise on the power supply in terms of Power Supply Noise Rejection (PSNR), with units of dBc. I'm not familiar with this figure and haven't had much success finding an equation. From context, however, it appears to be along the lines of PSNR = 10log(Pspur/Pcenter) dBc, where Pspur is the power of a particular spur caused by power supply injected ripple? Please correct me if I am mistaken.

Thank you
