Q33310F700386 from Seiko Epson, 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 | ST | input | Standby control: ST pin "H" or open gives the specified frequency output; "L" puts the output in high impedance and stops oscillation (VIH 80% Vcc min / VIL 20% Vcc max for SEF/SDF/SCF). |
| 2 | GND | power_in | Ground connection; a 0.01~0.1uF decoupling capacitor is recommended between VCC and GND close to the device. |
| 3 | OUT | output | CMOS clock output with VOH 90% Vcc min and VOL 10% Vcc max, rated for a 15 pF max load. |
| 4 | Vcc | power_in | Supply voltage: 1.8V typ (1.6-2.2V), 2.5V typ (2.2-3.0V or 2.2-2.7V) or 3.3V typ (2.7-3.6V) depending on series; add a 0.01~0.1uF decoupling capacitor to GND. |
