3. Operational Description

WSZWM110A00 is the ITU-T G.9959 Z-wave Module that acts as a communication controller for users

of a wireless device.

- Features

> Z-Wave ITU-T G.9959
> Z-Wave 9.6/40/100 kbit/s data rate
>128-bit AES security processor and hardware random number generator

- Time base of the RF frequency

For Z-wave IF and RF frequency, a crystal(32MHz) is a clock reference.

- Z-wave Tranceiver

The WSZWM110A00 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.

- Z-wave Receiver

The module is converted into a digital signal through the available receive signal of 900MHz and low noise
have a built-in amplifier to amplify the signal to the received signal to the low noise amplifiers to match
the signal strength and the amplified signal is inside Chip ADC from the main processor the packet
containing the information is interpreted.
