SG-8018CE 20.000000MHz TJHSA

Seiko Epson · Programmable Oscillators · SMD3225-4P

SG-8018CE 20.000000MHz TJHSA 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 ST input Standby control input for the S (Standby) function variant: High gives the specified frequency output on OUT, and Low forces OUT low (weak pull-down) and puts the device in standby with supply current reduced to I_std, with VIH at 70% VCC min and VIL at 30% VCC max.
2 GND power_in Ground reference; the 0.1 µF capacitor between VCC and GND should be placed on the device side of the PCB as close to the device as possible with short wiring.
3 OUT output CMOS clock output with VOH min 90% VCC and VOL max 10% VCC, specified for a maximum load of 15 pF.
4 VCC power_in Power supply input, rated 1.62 V to 3.63 V, with a 0.1 µF decoupling capacitor to GND recommended for optimum jitter.
