- 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

amplified before being sampled by a 12 MSPS ADC. The digitized signal is then demodulated in the digital
baseband. The filtering within the Rx path improves the EM35x’s co-existence with other 2.4 GHz
transceivers such as Zigbee/ 802.15.4-2003, IEEE 802.11-2007, and Bluetooth radios. The digital baseband
also provides gain control of the Rx path, both to enable the reception of small and large wanted signals
and to tolerate large interferers.

- Z-wave Tranceiver

The CY-LHDE01A is a fully integrated module with an on-board antenna that allows the establishment of a
Z-Wave network with minimum risk. The SD3503 chip is used with an external NVM (Serial Flash MEM),
32MHz crystal, power supply decoupling, SAW filter, matching circuit, and a PCB pattern Antenna.
