The ADF4159CCPZ: That 13 GHz ceiling makes it the right choice for Ku-band satellite links, point-to-point microwave backhaul, 5G mmWave test equipment, and automotive radar development. The part accepts CMOS or TTL reference inputs and delivers a CMOS output, with an integrated divider and multiplier (Yes/Yes) that lets you generate a wide range of output frequencies from a single reference. Supply range spans 1.62 V to 3.45 V, so it runs comfortably off a 1.8 V or 3.3 V rail without an extra regulator. The 2:1 input-to-output ratio means you can feed it from a single-ended or differential reference source.
Thermal and footprint — the 24-LFCSP exposed pad
The ADF4159CCPZ comes in a 24-lead WFQFN exposed-pad CSP (LFCSP) measuring 4x4 mm. Surface-mount only; no through-hole option.
