Overview
The ATS122B is a crystal made by CTS Electronic Components in a HC-49S package with 2 pins. -20℃~+70℃ 12.288MHz 18pF 40Ω ±30ppm ±50ppm HC-49S Crystals ROHS.
PCBKit's library has its KiCad symbol (Device:Crystal, from KiCad's library) and its footprint (EasyEDA_Cloud:HC-49US_L11.0-W4.6-P4.88, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C1669750).

Is there a KiCad symbol and footprint for the ATS122B?
Yes. The symbol is Device:Crystal and the footprint EasyEDA_Cloud:HC-49US_L11.0-W4.6-P4.88, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ATS122B?
HC-49S, with 2 pins. Its footprint is drawn on this page.
Where is the ATS122B datasheet?
CTS Electronic Components publishes it: the Datasheet link on this page opens it.
Where can I order the ATS122B?
JLCPCB lists it as part C1669750, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ATS122B?
Parts like it in the library: the S1C12288VWFAC by JYJE, the TXM12.288M0004322FBCDO00T by Yajingxin, the H1OEL89CSC-SUGYLC-12.288M by YXC and the X49SM12288MSD2SC by YXC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
