# RU38400013

**TROQ** · Oscillators · SMD2016-4P

RU38400013 from TROQ, in a SMD2016-4P. 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 | NC | unconnected | No connection; the pin table lists this pad as NC (enable voltage levels ELH/ELL are listed as 0 V, so no enable function is specified). |
| 2 | GND | power_in | Ground pad of the 38.400000 MHz CMOS oscillator. |
| 3 | OUTPUT | output | CMOS clock output at 38.400000 MHz with 45~55% symmetry, 5.0 nSec max rise/fall time and 15 pF load capacitance. |
| 4 | VDD | power_in | Supply voltage pin, 2.8 V, with current consumption of 5.0 mA max. |
