CMT2157B CMT2157B 240 MHz-960 MHz Single Chip OOK Transmitter with Encoder Instruction: CMT2157B is a single chip, high flexibility, ultra-low power consumption, OOK RF chip with encoder. It is ideal for wireless applications between 240 MHz to 960 MHz. The chip is fully compatible with the most commonly used coding formats such as 527, 1527, 2262 and 2240 in the market. In addition, it also supports various user-defined coding. The chip supports 4 freestanding buttons or up to 10 scanning buttons. Every key value can be individually configured. There is no diode isolation between the key combinations. The chip defaults to 1527 encoding and operates at 433.92 MHz when it is shipped.
