ECS-TXO-3225-160-TR from ECS, 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 | N/C or VCONT | unconnected | Not connected on the plain ECS-TXO-3225 TCXO; on the ECS-VTXO-3225 VC-TCXO option it is the control voltage input, 0.15 to 3.15 VDC, with ±5 PPM pullability. |
| 2 | Ground | power_in | Ground reference pin for the oscillator. |
| 3 | Output | output | HCMOS clock output with VOL of 0.5 VDC max, VOH of 80% VDD min, 40/60% symmetry at 50% VDD, 10 ns rise and fall times, and a 15 pF CMOS load. |
| 4 | VDD | power_in | Supply voltage input of 3.135 to 3.465 VDC (3.3 V nominal, ±5%). |
