20.3.5 Jitter Attenuation
Shown in Figure 33, Figure 34, Figure 35, and Fig-
ure 36 are jitter attenuation plots for the various re-
visions of the CS8427 when used with the
appropriate external PLL component values (as
noted in Table 7). The AES3 and IEC60958-4
specifications do not have allowances for locking
to sample rates less than 32 kHz or for locking to
the ILRCK input. These specifications state a max-
imum of 2 dB jitter gain or peaking.
