Descriptions:
CMT2300A is an ultra-low power, high performance, OOK (G)
FSK RF transceiver suitable for a variety of 140 to 1020 MHz
wireless applications. It is part of the CMOSTEK NextGenRF
RF product line. The product line contains the complete
transmitters, receivers and transceivers.The high integration of
CMT2300A simplifies the peripheral materials required in the
system design. Up to +20 dBmTx Power and -121 dBm
sensitivity optimize the performance of the application. It
supports a variety of packet formats and codec methodsto
meet the needs of various different applications.In addition,
CMT2300A also supports64-byte Tx/Rx FIFO, GPIO and
interrupt configuration, Duty-Cycle operation mode, channel
sensing, high-precision RSSI, low-voltage detection, power-on
reset, low frequency clock output, manual fast frequency
hopping, squelch and etc. The features make the application
design more flexible and differentiated. CMT2300A operates
from 1.8 V to 3.6 V. Only 8.5 mA current is consumed when the
sensitivity is -121 dBm, SuperLow Power mode can further
reduce the chip power consumption. Only 23mA Txcurrent is
consumed when the output power is 13dBm.
