RF synthesizer for IF and local-oscillator chains
The ADF4212LBCPZ is a single-channel PLL frequency synthesizer from Analog Devices, designed for RF/IF clock generation up to 2.4 GHz. It accepts CMOS or TTL reference inputs and delivers a differential clock output, with a 3:1 input-to-output ratio that lets you select among three reference sources. This part is typically specified by RF design engineers building the local-oscillator or IF chain in wireless infrastructure, test equipment, or satellite receivers—anywhere a clean, programmable clock at microwave frequencies is needed.
Supply range and temperature grade
Runs from 2.7V to 3.3V, so it fits comfortably on a 3.3V rail with margin for ripple.
Package and footprint reality
The 0.50 mm pitch demands a controlled soldering profile and a clean stencil aperture; rework with hot air is feasible if the board has a bottom-side thermocouple.
Lifecycle and supply posture
The active status means there is no forced cross-reference, but if the line is dark, the ADF4212LBRUZ (same silicon in a TSSOP tube) or the ADF4252BCPZ (3 GHz fractional-N) are functional alternatives worth evaluating.
