TXM30M0004252LBCEO00T

Yajingxin · Crystals · SMD2520-4P

TXM30M0004252LBCEO00T from Yajingxin, in a SMD2520-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 XTAL1 passive Crystal terminal connected to the resonator in the top-view drawing, for a 30.000000 MHz fundamental-mode crystal with 20 pF load capacitance.
2 NC unconnected Pad not wired to the resonator in the top-view drawing, and the datasheet states no function for it.
3 XTAL2 passive Crystal terminal connected to the resonator in the top-view drawing, for a 30.000000 MHz fundamental-mode crystal with 20 pF load capacitance.
4 NC unconnected Pad not wired to the resonator in the top-view drawing, and the datasheet states no function for it.
