Loop Filter Connection. This pin is the output side of the active loop filter op amp. Connect the PLL

active loop filter components (R1, C1, and C2) to this pin and LF_1 (Pin 1).

EP

GND

Exposed Pad. The exposed pad is a ground connection on the chip that must be soldered to the analog

ground of the printed circuit board (PCB) to ensure proper functionality and heat dissipation, noise, and

mechanical strength benefits.
