CMT2110A-ESR
HopeRF Micro electronics · RF Transceiver ICs · SOT-23-6
CMT2110A-ESR from HopeRF Micro electronics, in a SOT-23-6. 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 | XTAL | input | 26 MHz single-ended crystal oscillator input, or external 26 MHz reference clock input through a coupling capacitor at 0.3 to 0.7 Vpp amplitude. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | DATA | bidirectional | Data input for transmission, and the pin used to access the embedded EEPROM; when used as an input it is pulled down internally to GND in falling-edge transmission mode and pulled up internally to VDD in rising-edge transmission mode. |
| 4 | CLK | input | Clock pin that controls the device and also accesses the embedded EEPROM, pulled up internally to VDD. |
| 5 | RFO | output | Power amplifier RF output. |
| 6 | VDD | power_in | Power supply input, operating from 1.8 to 3.6 V. |
