# TG-5006CG-12H 26.0000M3

**Seiko Epson** · Temperature Compensated Crystal Oscillators (TCXOs) · SMD2520-4P

TG-5006CG-12H 26.0000M3 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 | N.C. | unconnected | TCXO version: no connection; keep OPEN or connect to GND, and it does not work as a ground pin (VC-TCXO version: Vc frequency control input, 0.9 V to 1.65 V centre depending on Vcc, 500 kΩ min input resistance). |
| 2 | GND | power_in | Ground connection; place a 0.01 µF to 0.1 µF bypass capacitor between Vcc and GND as close to the device as possible. |
| 3 | OUT | output | Clock output, 0.8 V peak-to-peak min, DC cut, 40% to 60% symmetry, into 10 kΩ // 10 pF load. |
| 4 | Vcc | power_in | Supply voltage 1.8 V, 2.8 V, 3.0 V or 3.3 V typ. (range 1.7 V to 3.465 V), with 0.01 µF to 0.1 µF bypass capacitor to GND. |
