Seiko Epson · Programmable Oscillators · SMD2520-4P
SG-8018CG 7.680000MHz 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: when high, the specified frequency is output on OUT; when low, OUT is pulled low by a weak pull-down and the device enters standby with supply current reduced to I_std (ST is the function selected for this ordering code, S; the same pin is OE on the P variant). |
| 2 | GND | power_in | Ground pin for the oscillator; 0.1 µF decoupling capacitor between VCC and GND is recommended close to the device for optimum jitter. |
| 3 | OUT | output | CMOS clock output at the programmed frequency (0.67 MHz to 170 MHz), with 15 pF maximum load and rise/fall time set by the ordering code (Default, Fast or Slow). |
| 4 | VCC | power_in | Power supply input; rated 1.62 V to 3.63 V per the datasheet specification table, with a 0.1 µF capacitor to GND recommended. |
