Descriptions
The CMT2157AW is a true single-chip, highly flexible, high performance, OOK/(G)FSK RF transmitter with embedded data encoder ideal 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 8 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 products of 868 MHz is available for immediate demands with no need of EEPROM programming. The CMT2157AW is part of the CMOSTEK NextGenRFTM family, together with CMT22xxW series receivers, they enable ultra low cost, low power consumption RF links.
