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. Supply range of 2.7 V to 5.5 V lets it run from a common RF rail.
Package and temperature grade
Housed in a 16-lead TSSOP, the ADF4113HVBRUZ fits a compact RF layout with minimal parasitic inductance on the charge-pump and supply pins. The -40°C to 85°C industrial temperature range qualifies it for outdoor telecom cabinets, engine-bay test instrumentation, and industrial RF links where ambient temperature swings are routine.
Lifecycle and sourcing
This part carries an Active product status with ROHS3 compliance.
