10.1.2 Jitter Attenuation

Figures 28 and 29 show the jitter-attenuation characteristics for the 32-192 kHz sample rate range when

used with the external PLL component values and locking modes as specified in Table 21.

The AES3 and IEC60958-4 specifications do not have allowances for locking to sample rates less than

32 kHz or for locking to the SAI_LRCK input. These specifications state a maximum of 2 dB jitter gain or

peaking.
