CMT2210LHESR

hoperf.com · Others · SOP-8

CMT2210LHESR from hoperf.com, 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 GND power_in Ground pin for the receiver.
2 RFIN input RF signal input to the internal LNA, matched to 50 Ω with a low-cost external matching network.
3 VDD5V power_in Power supply input; with VDD5V and VDDL left open the supply range is 3.0-5.5 V, and with them shorted it is 2.0-3.6 V.
4 VDDL power_out Power output pin that is shorted to VDD5V for 2.0-3.6 V operation and left open for 3.0-5.5 V operation.
5 DATA output Demodulated OOK receive data output.
6 NC unconnected No connection; leave floating.
7 NC unconnected No connection; leave floating.
8 XIN input Crystal oscillator input, or external reference clock input through a DC-blocking capacitor at 0.3-0.7 V peak-to-peak; the crystal is 19.7029 MHz (315 MHz) or 27.1412 MHz (433.92 MHz).
