* A separate analog supply is only necessary in applications where RMCK is used for a jitter sensitive task. For
applications where RMCK is not used for a jitter sensitive task, connect VA to VD via a ferrite bead. Keep decou-
pling capacitors between VA and AGND.

** See

“S/PDIF Receiver” on page 27

and

“External AES3/SPDIF/IEC60958 Receiver Components” on page 49

for typical input configurations and recommended input circuits.

*** For best jitter performance, connect the filter ground directly to the AGND pin. See

Table 6 on page 54

for PLL

filter values.
