Sets internal biasing currents; connect to ground
Sets internal CP current range, nominally 4.8 mA (CP_lsb = 600 μA);
actual current can be calculated by CP_lsb = 3.06/CPRSET;
connect to ground
Bypass for internal LDO regulator; necessary for LDO stability;

Differential mode (can accommodate single-ended input
by ac grounding undriven input)
Frequencies below about 1 MHz should be dc-coupled;
be careful to match V
PLL figure of merit increases with increasing slew rate;
