Pin Layout Guide
AVDD15D
External
– Use dedicated power/ground pins for PLL
– Power cuts are required to provide on-chip isolation
→ between dedicated PLL power/ground and all other power/ground
– Use good power and ground source on board

FIN
External
– Do not place noisy, high frequency and high power consuming circuitry
pads near the FIN pin.
– Use proper low jitter reference clock
FOUT
External/Internal – Do not place noisy, high frequency and high power consuming circuitry
pads near the FOUT pin.
– Internal routing path should be as short as possible. This will minimize
loading effect.
– FOUT signals should not be crossed by any signals and should not run
next to digital signals. This will minimize capacitive coupling between the
two signals.
FILTER
External
– Do not place the noisy, high frequency and high power consuming circuitry
pads near the FILTER.
– Ground shielding is needed for internal routing path.
– FILTER routing path should not be crossed by any other signals and
should not be placed next to digital signals.
– External loop filter pin should be placed between analog power and
ground to avoid stray coupling outside the chip and magnetic coupling via
bond wires.
– External loop filter components and internal routing should be as short as
possible.
