Test Conditions/Comments
Antibacklash pulse width = 1.3 ns, 2.9 ns
Antibacklash pulse width = 6.0 ns
Antibacklash pulse width = 1.3 ns, 2.9 ns
0x017[1:0] = 01b
0x017[1:0] = 00b; 0x017[1:0] = 11b
0x017[1:0] = 10b
Programmable
With CPRSET = 5.1 kΩ; higher ICP is possible by
changing CPRSET
With CPRSET = 5.1 kΩ; lower ICP is possible by
changing CPRSET
Charge pump voltage set to VCP/2
0.5 < VCP < VCP − 0.5 V; VCP is the voltage on the CP (charge
pump) pin; VCP is the voltage on the VCP power supply pin
0.5 < VCP < VCP − 0.5 V
VCP = VCP/2 V
A, B counter input frequency (prescaler input
frequency divided by P)
Register 0x019[2:0]; see Table 53
