DESCRIPTION
1
VRA_PLL
Voltage reference for PLL analog supply 1.8 V. A pin-out of the internally regulated
1.8-V power used by PLL logic. A 0.1-µF low ESR capacitor should be connected
between this terminal and AVSS_PLL. This terminal must not be used to power
external devices.

PLL_FLTM
AO
PLL negative input. Connected to PLL_FLT_RTN via an RC network
4
PLL_FLTP
AI
PLL positive input. Connected to PLL_FLT_RTN via an RC network
