FKSSD1025

Diodes Incorporated · Crystal Oscillators · SMD3225-4P

FKSSD1025 from Diodes Incorporated, in a SMD3225-4P. 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 OE input Output enable input: at or above 0.7 VDD (or open) enables the output, while below 0.3 VDD puts the output in Hi-Z low-power standby, with an internal pullup of 50 kΩ, output disable delay of 100 ns and output enable delay of 10 ms.
2 Ground power_in Ground reference pin for the oscillator supply.
3 Clock Output output CMOS clock output with VOL at most 10% VDD and VOH at least 90% VDD into a 15 pF load, duty cycle 45-55% measured at 50% VDD, and rise/fall time of 5 ns maximum measured at 10/90%.
4 VDD power_in Supply voltage pin rated 2.97 V min, 3.3 V typ, 3.63 V max.
