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 product of
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
CMT2250AW is part of the CMOSTEK NextGenRFTM family,
together with CMT215x series transmitters, they enable
ultra low cost, low power consumption RF links.
