SG-8018CG 50.000000MHz TJHSA

Seiko Epson · Pre-programmed Oscillators · SMD2520-4P

SG-8018CG 50.000000MHz TJHSA from Seiko Epson, in a SMD2520-4P. 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, active-low (ST¯¯): High gives the specified frequency output on OUT; Low pulls OUT low (weak pull down) and enters standby mode with supply current reduced to I_std (VIH 70 % VCC min, VIL 30 % VCC max).
2 GND power_in Power ground.
3 OUT output CMOS clock output, 0.67 MHz to 170 MHz, with a maximum load of 15 pF.
4 VCC power_in Power supply, 1.62 V to 3.63 V; place a 0.1 μF capacitor between VCC and GND close to the device.
