F25208MUBCE2O from TAE(Zhejiang Abel Elec), 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	E/D	input	Enable/disable (tri-state) control: switch H or open gives oscillation output, L gives High-Z output, with 100nsec max disable time and 10msec max enable (start-up) time.
2	GND	power_in	Ground return of the oscillator, tied to the 0.01uF bypass and load capacitor ground in the measurement circuit.
3	OUT	output	CMOS clock output (8.000MHz), Voh 90%Vdd min and Vol 10%Vdd max, 15pF max load, 40-60% symmetry, 8ns max rise/fall time.
4	VDD	power_in	Power supply input 1.8V to 3.3V, 5mA max input current, with 0.01uF bypass capacitor.
