The device integrates a data decoder that is not only compatible with the most common used encoding format of 1527 and 2262, QFN16 (3X3) 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 product of DIP16 433.92 MHz is 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 CMT2250A TM is part of the CMOSTEK NextGenRF family, together with SOP16 CMT215x series transmitters, they enable ultra low cost, low power consumption RF links.
