ECS-TXO-3225MV-320-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 | Tri-State | input | Tri-state control: high or NC keeps the output active, low disables the output to High-Z. |
| 2 | Ground | power_in | Ground connection. |
| 3 | Output | output | HCMOS clock output, rated for a 15 pF CMOS load with VOL 10% Vdd and VOH 90% Vdd. |
| 4 | VDD | power_in | Supply voltage input, 1.7 V to 3.6 V. |
