Nominally 3.3 V to 5.0 V ± 5%
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;
connect to ground
Test Conditions/Comments
See Figure 15
See Figure 10

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 (FOM) increases with increasing slew rate; see
