Descriptions

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 NextGenRF^TMfamily,

together with CMT215x series transmitters, they enable

ultra high performance, low power consumption RF links.
