The CMT2250AW is HopeRF CMT single-chip, ultra low power and high performance device that consists of an OOK RF receiver, with 1920, 1527 and 2262 embedded data Decoder and 4 data output pins for various 300 to 480 MHz wireless applications.
Descriptions
The CMT2250AW is a true single-chip, ultra low power and high performance device that consists of an OOK RF receiver, a data decoder and 4 data output pins for various 300 to 480 MHz wireless applications.The device integrates a data decoder that is not only compatible with the most common used encoding format of 1527 and 2262, but also a more efficient, flexible and powerful format of 1920 designed by CMOSTEK.The device delivers sensitivity up to -114 dBm while consuming only 3.8 mA current when it is always on.An embedded EEPROM allows the frequency, symbol rate and other features to be programmed into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock products of 315/433.92 MHz are available for immediate demands with no need of EEPROM programming. When pairing the device to CMOSTEK transmitters, the synchronization ID can be programmed into both of the transmitter and receiver during the manufacturing phase, or studied by the receiver from the transmitter remotely by end customers. The CMT2250AW is part of the CMOSTEK NextGenRFTM family, together with CMT215xW transmitters, they enable ultra low cost, low power consumption RF links.
