Vollgo · RF Transceiver ICs · SOP-8
VG480R from Vollgo, 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 | GND | power_in | Ground pin for the receiver. |
| 2 | ANT | input | RF signal input pin for the antenna. |
| 3 | VDD | power_in | Supply pin; the datasheet specifies DC 2.0 to 5.5 V (absolute maximum -0.3 V to 5.5 V). |
| 4 | CTH | input | Selects the reference signal mode for the internal data comparator; the CTH source impedance is 145 kΩ and leakage is ±100 nA at TA = +85°C. |
| 5 | DO | output | Demodulated data signal output. |
| 6 | SHUT | input | Shutdown control: connect to VDD for shutdown mode and to GND for operating mode; receiver start-up from SHUT low is 3 ms. |
| 7 | NC | unconnected | No connection; leave floating. |
| 8 | REFOSC | input | External crystal connection for the reference oscillator (input impedance 290 kΩ); it can alternatively be driven by an external reference clock through a coupling capacitor with a 0.3 V to 0.7 V peak-to-peak amplitude. |
