描述

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.
