8121S-32.000NNWVFTL

HCI · Temperature Compensated Crystal Oscillators (TCXO) · SMD2016-4P

8121S-32.000NNWVFTL from HCI, 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 GND/NC power_in Ground or no connect (table lists 'Ground GND or N.C.'); the datasheet gives no further limits.
2 GND power_in Ground pin; the metal lid is connected to GND at pin 2.
3 OUTPUT output RF clipped sine wave output, 0.8Vp-p minimum into a 10kΩ/10pF load.
4 VCC power_in Supply voltage pin for 1.8V, 2.5V, 2.8V, 3.0V or 3.3V operation.

CAD (KiCad official)

  • Symbol: 8121S-32.000NNWVFTL
  • Footprint: Crystal:Crystal_SMD_2016-4Pin_2.0x1.6mm
  • 3D model: SMD2016-4P (KiCad packages3D, STEP)
  • 3D model files: 8121s-32-000nnwvftl-etched.step / 8121s-32-000nnwvftl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 8121s-32-000nnwvftl.step / 8121s-32-000nnwvftl.glb are the bare package body.
