SG-8018CG 8.000000MHz 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 with overline): 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. This variant is ordered with function code S (Standby); the same pin is OE (output enable) on the P-function variant. |
| 2 | GND | power_in | Ground reference; 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 at the specified frequency, with a maximum load of 15 pF (L_CMOS) and rise/fall time set by the Default, Fast or Slow mode. |
| 4 | VCC | power_in | Power supply, rated 1.62 V to 3.63 V (minimum 1.62 V for start-up timing). |
