PIN DESCRIPTIONS

VA—Analog Positive Supply: Pin 34

Analog positive supply for clock generator. Nominally +3.3 V.

AGND—Analog Supply Ground: Pin 35

Analog ground for clock generator PLL.

VD1, VD2, VD3—Digital Positive Supply: Pins 1, 12, 23

Digital positive supplies. Nominally +3.3 V.

DGND1, DGND2, DGND3—Digital Supply Ground: Pins 2, 13, 24

Digital ground.

FILT1—Phase-Locked Loop Filter: Pin 33

Connects to an external filter for the on-chip phase-locked loop. This pin does not meet Cirrus

Logic’s ESD tolerance of 2000 V using the human body model. This pin will tolerate ESD of

1000 V using the human body model.
