Description
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
TM
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
methods to meet the needs of various different applications.
In addition, CMT2300A also supports 64-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 Tx current is consumed when the
output power is 13 dBm.
