Description

The CMT2251A is a true single-chip, ultra low power and high performance device that consists of an OOK RF receiver, a data decoder and 1 PWM output pin for various 300 to 480 MHz wireless applications. 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 designed by CMOSTEK. The device delivers sensitivity up to -114 dBm while consuming only 3.8 mA current when it is always on.
