Seiko Epson · Programmable Oscillators · SMD2520-4P
SG-8018CG 20.000000MHz 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 | Active-low standby input: High gives the specified frequency output on OUT, while Low forces OUT low (weak pull-down) and puts the device into standby with supply current reduced to I_std. |
| 2 | GND | power_in | Ground pin for the oscillator; a 0.1 µF decoupling capacitor between VCC and GND should be placed as close to the device as possible for optimum jitter. |
| 3 | OUT | output | CMOS clock output, specified at a load of up to 15 pF (L_CMOS max) with the rise/fall time set by the ordering code. |
| 4 | VCC | power_in | Power supply input; the rated supply range is 1.62 V to 3.63 V. |
