SG-8018CE 33.333000MHz 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 at OUT, Low pulls OUT low (weak pull down) with only the output driver disabled; VIH 70 % VCC min, VIL 30 % VCC max. |
| 2 | GND | power_in | Ground; place a 0.1 μF capacitor between VCC and GND close to the device for best jitter performance. |
| 3 | OUT | output | CMOS clock output, 0.67 MHz to 170 MHz, rated for a load of 15 pF max. |
| 4 | VCC | power_in | Power supply, 1.62 V to 3.63 V (1.8 V, 2.5 V or 3.3 V typ.). |
