- Time base of the RF frequency
For ZigBee IF and RF frequency, a crystal(24MHz) is a clock reference.
For Z-wave IF and RF frequency, a crystal(32MHz) is a clock reference.
- ZigBee Transmission
The ZigBee Tx path produces an O-QPSK-modulated signal using the analog front end and digital
baseband. The area- and power-efficient Tx architecture uses a two-point modulation scheme to modulate
the RF signal generated by the synthesizer. The modulated RF signal is fed to the integrated PA and then
out of the EM357.
- ZigBee Receiver
The ZigBee Rx path uses a low-IF, super-heterodyne receiver that rejects the image frequency using
complex mixing and polyphase filtering. In the analog domain, the input RF signal from the antenna is first
amplified and mixed down to a 4 MHz IF frequency. The mixers' output is filtered, combined, and
