SG-8101CE 40.000000MHz TBGPA 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 for the P (Output Enable) function: High gives the specified frequency at OUT, Low pulls OUT low (weak pull down) and disables only the output driver; VIH is 70 % VCC min and VIL is 30 % VCC max. |
| 2 | GND | power_in | Power ground. |
| 3 | OUT | output | CMOS clock output, rated for a 15 pF max load, with 0.67 MHz to 170 MHz output frequency range. |
| 4 | VCC | power_in | Power supply of 1.62 V to 3.63 V; place a 0.1 µF capacitor between VCC and GND close to the device. |
