PLL frequency synthesizer for RF local oscillators
The Analog Devices ADF4113HVBRUZ is a single-channel PLL frequency synthesizer designed for RF local-oscillator generation. It accepts CMOS or TTL reference inputs and delivers a clock output, covering a maximum frequency of 4 GHz. The charge-pump output is rated for high-voltage operation — the 'HV' suffix — which gives the loop filter wider tuning range without an external level shifter.
Housed in a 16-lead TSSOP, the ADF4113HVBRUZ fits a compact RF layout with minimal parasitic inductance on the charge-pump and supply pins.
