Descriptions
The CMT2150A is a true single-chip, highly flexible, high
performance, OOK RF transmitter with embedded data
encoder ideal for 240 to 480 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 433.92 MHz is available
for immediate demands without the need of EEPROM
programming. The CMT2150A is part of the CMOSTEK
TM
NextGenRF family, together with CMT225x series
receivers, they enable ultra low cost, low power
consumption RF links.
