SG-8018CE 25.000000 MHZ TJHPA 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 | OE | input | Output enable: High gives the specified frequency output from OUT; Low forces OUT low (weak pull-down) and disables only the output driver. Do not leave this pin open. |
| 2 | GND | power_in | Ground pin for the oscillator; a 0.1 µF capacitor should be placed between VCC and GND for optimum jitter performance. |
| 3 | OUT | output | CMOS clock output at the programmed frequency (0.67 MHz to 170 MHz), with a maximum load of 15 pF. |
| 4 | VCC | power_in | Power supply pin, rated 1.62 V to 3.63 V for this series. |
