High-performance FSK Wireless Receiver Module cmt2219
Product Description
High-performance FSK Wireless Receiver Module with cmt2219 chip
Module introduction
The DL-RXC2219A/B is an ultra-low power, high performance, OOK and (G)FSK receiver 868 MHz wireless applications. 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 RF PDK.
The DL-RXC2219A/B operates from a supply voltage of 1.8 V to 3.6V, 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. DL-RXC2219A/B receiver together with the DL-TXC2119A/B transmitter enables a powerful RF link.
