ECS-327ATQMV-AS-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 or NC | input | Output enable: a level at or above 0.7 x Vdd (min) or no connection keeps the output active, while a level at or below 0.3 x Vdd (max) puts the output in high impedance. |
| 2 | Gnd | power_in | Ground reference pin for the oscillator. |
| 3 | Output | output | HCMOS clock output with VOL at most 10% Vdd and VOH at least 90% Vdd, specified for a 15 pF CMOS load. |
| 4 | Vdd | power_in | Supply voltage pin, specified from 1.62 V to 3.63 V. |
