550 MHz PLL synthesizer for RF local-oscillator generation
The ADF4110BRUZ is an Analog Devices PLL frequency synthesizer rated to 550 MHz maximum input frequency, suited for generating local-oscillator or IF clocks in RF receivers and transmitters. It accepts CMOS or TTL reference inputs and delivers a single-ended clock output, with a 2:1 input-to-output ratio — one of the two inputs can be selected as the PLL reference. Operating from 2.7V to 5.5V and rated over -40°C to 85°C, it fits base-station, radio-link, and industrial frequency-synthesis applications where the supply rail may vary.
16-TSSOP footprint and supply-range flexibility
Housed in a 16-TSSOP package with 0.173-inch body width, the 0.65 mm pitch is layout-compatible with typical MCU or FPGA peripheral areas. The wide supply range (2.7V to 5.5V) lets it share a 3.3V or 5V rail without a dedicated regulator.
