**JYJE** · RF Transceiver ICs · SOP-8

JR2306ARZ from JYJE, 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 | Antenna pin, RF signal input that requires an external matching network. |
| 2 | GND | power_in | Ground. |
| 3 | VDD | power_in | 2.5-5.5 V power supply input. |
| 4 | SHUT | input | Shutdown control pin: high level enters shutdown mode, low level enters working mode. |
| 5 | DOUT | output | Data output. |
| 6 | CTH | input | External filter capacitor pin that sets the slicing level of the data comparator. |
| 7 | CAGC | input | Automatic gain control pin with an external filter capacitor. |
| 8 | XOSC | input | Crystal oscillator input pin for an external crystal or reference clock. |
