Replacement verdict
Compatible functional replacement candidate
The ADF4002BCPZ and ADF4001BCPZ are both single PLL frequency synthesizers in a 20-lead LFCSP package with a shared 3-wire serial interface and comparable supply requirements, making the ADF4002BCPZ a viable functional replacement candidate for the ADF4001BCPZ in many designs. However, the ADF4002BCPZ adds a programmable phase detector polarity and charge pump current range that differ from the ADF4001BCPZ, so loop filter and lock detect behavior should be validated against the target application before substitution.
