SG-8018CE 8.000000MHz TJHPA

Seiko Epson · Programmable Oscillators · SMD3225-4P

SG-8018CE 8.000000MHz 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 input: High gives the specified frequency on OUT, and Low forces OUT low (weak pull-down) by disabling only the output driver, with VIH of 70% VCC min and VIL of 30% VCC max.
2 GND power_in Ground reference for the oscillator; a 0.1 µF capacitor between VCC and GND should be placed as close to the device as possible for optimum jitter performance.
3 OUT output CMOS clock output with VOH of 90% VCC min and VOL of 10% VCC max, specified for a 15 pF max load.
4 VCC power_in Power supply, rated 1.62 V to 3.63 V for this part, with a 0.1 µF decoupling capacitor to GND recommended.
