RF/IF synthesizer for L-band and ISM-band designs
The ADF4212LBRUZ is a PLL-based clock/frequency synthesizer from Analog Devices, targeting RF and IF synthesis up to 2.4 GHz. The 3:1 input-to-output ratio and differential I/O allow it to drive mixers and modulators directly in a receiver or transmitter chain.
Supply and temperature grade for outdoor infrastructure
Runs on a 2.7V to 3.3V supply, which matches standard 3.3V RF front-end rails and leaves headroom for regulation droop.
20-TSSOP footprint and differential I/O routing
Housed in a 20-lead TSSOP (4.40 mm width) — the 0.65 mm pitch is routable on a 2-layer board with careful trace spacing for the differential clock outputs. The differential output pair (Yes/Yes) reduces common-mode noise coupling into the downstream PLL or mixer.
