Descriptions

The CMT2210/17A devices are ultra low power, high

performance, low-cost OOK stand-alone RF receiver for

various 300 to 960 MHz wireless applications. The

CMT2210A covers the frequency range from 300 to 480

MHz while the CMT2217A covers the 300 to 960 MHz

frequency range. They are part of the CMOSTEK

NextGenRF

family, which includes a complete line of

transmitters, receivers and transceivers. An embedded

EEPROM allows the frequency, symbol rate and other

nRSTO

QFN16 (3

features to be programmed into the device using the

CMOSTEK USB Programmer and RFPDK. Alternatively, in

stock products of 433.92/868.35 MHz are available for

immediate demands without the need of EEPROM

programming. When the CMT2210/17A is always on, it

consumes only 3.8 mA current while achieving -113 dBm

receiving sensitivity. It consumes even less power when

working in duty-cycle operation mode via the built-in sleep

timer. The CMT2210/17A receiver together with the

CMT211x transmitter enables an ultra low cost RF link.

Notes:

[1]. Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is a stress

rating only and functional operation of the device under these conditions is not implied. Exposure to maximum rating

conditions for extended periods may affect device reliability.

[2]. The CMT2210/17A is high-performance RF integrated circuits with VCON/P pins having an ESD rating < 2 kV HBM.

Handling and assembly of this device should only be done at ESD-protected workstations.
