The device integrates a data decoder that is not only compatible with the most common used packet format of 1527, but also a more efficient, flexible and powerful format of 1920 des igned by CMOSTEK. The device delivers sensitivity up QFN16 (3X3) 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 the RFPDK. Alternatively, in stock products of 433.92 MHz are 12 11 10 9 available for immediate demands with no need of EEPROM 8 pr ogramming. When pairing the device to CMOSTEK GND 13 XIN transmitter, the synchronization ID can be programmed into RFIN 7 XOUT 14 both of the transmitter and receiver during the GND 15 6 NC manufacturing phase, or studied by the receiver from the 5 VDD 16 PWM/TEST transmitter remotely by end customers. The CMT2251A is TM 1 2 3 4 part of the CMOSTEK NextGenRF family, together with CMT215x transmitters, they enable ultra low cost, low power consumption RF links.
