The CMT2257AW is a true single-chip, ultra low power and high performance device that consists of an OOK/(G)FSK RF receiver, a data decoder and 4 data output pins for various 300 to 960 MHz wireless applications. The device integrates a data decoder which is compatible with the most common used encoding format of 1527 and 2262, as well as a more flexible format of 1920 designed by CMOSTEK. The device delivers sensitivity up to -109 dBm (FSK, 9.6 ksps symbol rate, 868.35 MHz) while consuming only 5.7 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 868.35 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 CMT2257AW is part of the CMOSTEK NextGenRFTM family, together with CMT215x series transmitters, they enable ultra high performance, low power consumption RF links.
