Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO1 | passive | Crystal oscillator input pin for the reference crystal (X1), with no electrical limits given in the datasheet. |

| 4 | GNDRF | power_in | RF ground pin that must be connected to the RF ground plane. |
| 5 | VDD | power_in | Power supply input, specified at DC 2 V to 5.5 V in the pin table and 1.8 V to 5.5 V in the product description, with a recommended operating range of 2.2 V to 5.0 V. |
| 6 | SQ | input | Squelch control logic input where grounding enables squelch and leaving it floating disables squelch. |
| 7 | SEL0 | input | Logic control input with an active internal pull-up that is used together with SEL1 to set the demodulator low-pass filter bandwidth and data rate. |
| 8 | SHDN | input | Chip shutdown input that is active low, where a high level puts the device into power-saving mode with total current below 1 µA. |
| 9 | GND | power_in | Ground pin for the device. |
| 10 | DO | output | Decoded data output that goes low when squelch detects noise and follows the demodulated signal otherwise. |
