- Changed Figure 28Go
- Added charge pump gain tableGo
- Deleted sentence 'When the device comes out of the powered down state, either by resuming the POWERDOWN bit to zero or by pulling back CE pin HIGH (if it was powered down by CE pin), it is required that register R0 with FCAL_EN = 1 be programmed again to re-calibrate the device.' from the Powerdown sectionGo
- Added sentence 'The wake-up time for the device to come out of the powered state is adjustable.' to the Powerdown sectionGo
- Changed Programming Sequence step from: Wait 100 µs… to: Wait 500 µs…Go
- Changed R6 initial programming from: No to: DependsGo
- Changed R52 initial programming from: No to: YesGo
- Added LDO_DLY in register R6 Go
- Changed R15[0] from: 1 to: 0 Go
- Changed R15 POR value Go
- Changed R20[14] from: 0 to: 1Go
- Changed R52[0] from: 0 to: 1 Go
- Changed register R0, FCAL_HPFD_ADJ value definitionGo

- Changed RAMP_THRESH value suggestionGo
- Deleted paragraph 'For ramping that are not calibration free, the ramp waveform is more like a staircase ramp. For all automatic ramping waveforms, be aware that there is a very small phase disturbance as the VCO crosses over the integer boundary, so one might consider using the input Multiplier to avoid these or timing the VCO calibration at integer boundaries.' from the Automatic Ramping Mode sectionGo
- Changed ADR_HOLD = 1 to ADD_HOLD = 1Go
- Added an application section for external loop filterGo
- Added an application section for powerup wake up timeGo
