CMT2210LB-ESR

HopeRF Micro electronics · RF Transceiver ICs · SOP-8

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.
