Descriptions

The CMT2157A is a true single-chip, highly flexible, high

performance, (G)FSK/OOK RF transmitter with embedded

data encoder ideally for 240 to 960 MHz wireless

applications. The device integrates a data encoder 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. Up

to 7 configurable push buttons are supported in multiple

button modes. When pairing the device to CMOSTEK

receiver, 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. An embedded

EEPROM allows the RF and encoder parameters to be

programmed into the chip using the CMOSTEK USB

Programmer and the RFPDK. Alternatively, in stock

product of 868.35 MHz is available for immediate demands

without the need of EEPROM programming. The

CMT2157A is part of the CMOSTEK NextGenRF^TMfamily,

together with CMT225x series receivers, they enable ultra

low cost, low power consumption RF links.
