1XXB16369MBA from KDS Daishinku, in a SMD2520-4P. 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 | GND | power_in | Vcont control voltage input (+1.4V±1V at Vcc≥2.6V) on the VC-TCXO DSA221SDN, GND on the TCXO DSB221SDN, or ENABLE/DISABLE stand-by control on the DSB221SDNB. |
| 2 | GND | power_in | Ground connection. |
| 3 | OUTPUT | output | Clipped sinewave, DC-coupled output, 0.8Vp-p min. into 10kΩ//10pF load. |
| 4 | VCC | power_in | Supply voltage, +1.68 to +3.5V range (nominal +1.8V/+2.6V/+2.8V/+3.0V/+3.3V). |
