CMT2219A

The CMT2219A is an ultra low power, high performance, OOK and (G)FSK receiver for various 300 to 960 MHz wireless applications.

Description

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 NextGenRFTM family, 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.
