CMT2210LB-ESR from HopeRF Micro electronics, 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 | SDA | bidirectional | 3-wire SPI data input and output for EEPROM programming; a pull-up resistor (R1, 10 kΩ in the typical application) is required if the EEPROM is accessed. |
| 2 | SCL | input | 3-wire SPI clock input for EEPROM programming, internally pulled low. |
| 3 | DOUT | output | Received data output (demodulated OOK data from the receiver). |
| 4 | XIN | input | Crystal oscillator input or external reference clock input; an external reference needs a coupling capacitor and a peak-to-peak amplitude of 0.3 to 0.7 V. |
| 5 | RFIN | input | RF signal input to the LNA. |
| 6 | GND | power_in | Ground. |
| 7 | VDD | power_in | Power supply input; operating supply voltage is 1.8 to 3.6 V. |
| 8 | CSB | input | 3-wire SPI chip select input for EEPROM programming, internally pulled high. |
