VIBRATION · RF Chips · SOP-8
VT831R 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 | RFIN | input | RF signal input pin, connected to an external matching network. |
| 2 | GND | power_in | Ground pin. |
| 3 | VDD | power_in | Power supply input, operating from 2.1 to 5.5 V. |
| 4 | ST | input | Chip shutdown control: a high level shuts the chip down and a low level enables it. |
| 5 | DOUT | output | Receive data output. |
| 6 | CTH | bidirectional | Used for receive data filtering and requires an external data filter capacitor (0.47 uF in the reference BOM). |
| 7 | AGC | bidirectional | Automatic gain control pin that requires an external filter capacitor, whose value affects startup time and interference immunity. |
| 8 | XI | bidirectional | Crystal oscillator input pin for connecting the external crystal. |
