AK1548 Datasheet, PDF (10/42 Pages) Asahi Kasei Microsystems – 8GHz Low Noise Integer-N Frequency Synthesizer

[AK1548]
Note 3) When [PDN] is ”1”, the total power supply current of the AK1548 is “IDD2+IDD3+ Charge pump current”.
Note 4) The current depending on Phase Detector Frequency isn’t included. IDD3 is the stationary current that
charge pump circuit consumes.
