Descriptions

The CMT2219A is an ultra low power, high performance,

OOK and (G)FSK receiver for various 300 to 960 MHz

wireless applications. It is part of the CMOSTEK

NextGenRF^TMfamily, which includes a complete line of

transmitters, receivers and transceivers. All features can be

configured either by off-line EEPROM programming or

on-line registers writing. The configuration file to be written

into the registers is generated by the smart RFPDK. The

CMT2219A operates from a supply voltage of 1.8 V to 3.6

V, when it is always on, it consumes only 5.7 mA current

while achieving -109 dBm receiving sensitivity (FSK, 9.6

ksps symbol rate, 868.35 MHz), and only 60 nA sleep

current for superior battery life. The device supports packet

handling, 32-byte FIFO, Manchester decoding and data

de-whitening for the received data processing. Besides the

demodulated data and the sync clock, the device can also

send out the power-on reset, the system clock, as well as 2

configurable interrupts for the external device. CMT2219A

receiver together with the CMT211xA transmitter enables a

powerful RF link.
