# VG197A

**VIBRATION** · RF Transceiver ICs · SOP-8

VG197A from VIBRATION, in a SOP-8. 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 | XO | output | Crystal oscillator output; the 12MHz crystal load capacitance is recommended as 22pF. |
| 2 | XI | input | Crystal oscillator input, used with the 12MHz crystal (load capacitance recommended as 22pF). |
| 3 | VSS | power_in | Ground pin for the device. |
| 4 | ANT | passive | RF input/output port to the antenna; the maximum input RF signal strength is +10 dBm. |
| 5 | CS | input | Active-low chip enable; pulling CS low wakes the chip from sleep mode, and the crystal needs about 1.5ms to settle before data access. |
| 6 | CLK | input | I2C/SPI clock input. |
| 7 | SDA | bidirectional | I2C/SPI data line; on VG197A it is the shared 3-wire SPI data line, and VG197A has no internal pull-up on SDA or SCL. |
| 8 | VDD33 | power_in | 3.3V supply input; the operating supply range is 1.9V to 3.6V with an absolute maximum of 3.7V. |

## CAD (KiCad official)

- Symbol: `VG197A`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `vg197a-etched.step` / `vg197a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `vg197a.step` / `vg197a.glb` are the bare package body.
