Is there a KiCad symbol and footprint for the STW81200?
Yes. The symbol is Celestial_RF_Frequency_Synth:STMICRO STW81200 and the footprint EasyEDA_Cloud:QFN-36_L6.0-W6.0-P0.50-TL-EP4.1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the STW81200?
VFQFPN-36(6x6), with 37 pins. Its footprint is drawn on this page.
Where is the STW81200 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STW81200?
JLCPCB lists it as part C2662665, with 0 in stock; the sellers' links on this page open their listings.
What can replace the STW81200?
Parts like it in the library: the SI5317C-C-GMR by Silicon Labs, the SI5326C-C-GMR by Silicon Labs, the SI5317B-C-GMR by Silicon Labs and the SI5323-C-GMR by Silicon Labs. Check their datasheets: a part that fits the footprint may still differ in its ratings.
