LR680K
蜂鸟无线 · RF Transceiver ICs · SOP-8
LR680K from 蜂鸟无线, 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 | VSSRF | power_in | Ground (RF ground) pin of the receiver. |
| 2 | ANT | input | Antenna input for the RF signal. |
| 3 | VDDRF | power_in | Positive power supply pin (datasheet supply voltage 2 to 5.5 V, typical 5 V). |
| 4 | CTH | passive | Demodulator low-pass filter output with internal 120 kOhm output resistance, connected to ground through an external capacitor (330 uF recommended), providing the average-voltage reference for the comparator. |
| 5 | DOUT | output | Data output pin. |
| 6 | SHUT | input | Enable pin: 0 for normal operation, VDD to shut down; requires external control and is high-impedance internally. |
| 7 | CAGC | passive | AGC module filter capacitor pin, connected to ground through an external capacitor (1 uF recommended). |
| 8 | OSC | passive | Reference oscillator input for a crystal or ceramic resonator (crystal required in narrow-bandwidth mode); a clock signal can also be driven directly into it. |
