1. Descriptions of RF Receiver IC CMT2217AW:


The CMT2217AW is an ultra low power, high performance, low-cost (OOK stand -alone RF receiver for various 300 to 960 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. 


An embedded EEPROM allows the frequency, symbol rate and other features to be programmed into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock products of 315/915 MHz are available for immediate demands with no need of EEPROM programming. The CMT2217AW operates from a supply voltage of 1.8V to 3.6V, when it is always on, it consumes only 6 mA current while achieving -109 dBm receiving sensitivity (@9.6 ksps symbol rate). 


It consumes even less power when working in duty-cycle operation mode via the built-in sleep timer. The device provides demodulated data, power-on reset output as well as a system clock output for use by an external microcontroller or decoder. CMT2217AWreceiver together with the CMT2217AW transmitter enables an ultra low cost RF link.
