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

the CMOSTEK

QFN16 (3

NextGenRF

family, which includes a complete line of

transmitters, receivers and transceivers. All features can be

VCON

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.
