ECS-TXO-3225-200-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 | On the standard ECS-TXO-3225 TCXO this pin is no-connect; the datasheet gives a control voltage of +0.15 to +3.15 VDC (typ. +1.65 VDC) with ±5 PPM pullability only for the ECS-VTXO-3225 VC-TCXO option. |
| 2 | Ground | power_in | Ground connection for the oscillator, as listed in the datasheet pin connections. |
| 3 | Output | output | HCMOS clock output with VOL max 0.5 VDC, VOH min 80% VDD, 40/60% symmetry at 50% VDD, 10 ns rise/fall times and a 15 pF CMOS load. |
| 4 | VDD | power_in | Supply pin with an input voltage of +3.135 to +3.465 VDC (3.3 V nominal) and typical current consumption of 6.0 mA. |
