IT900A

What is the protocol running within IT900A?

The protocol stack within IT900A is called Y-Net.

The Y-Net stack provides a set of advanced communication services enabling a standard, rapid and simple method of development for low cost command and control networking applications over the power line media. The services provided by the Y-Net protocol stack enable developers to focus their efforts on the implementation of their applications, rather than on the communication and networking function.

What is IT900A's speed?

Data rates up to 500 Kbps for FCC band and ARIB, 150 Kbps in CENELEC band

Is the IT900A back compatible & interoperable with IT700 and IT900?

Yes. The IT900A is fully back compatible and interoperable with IT700 and IT900. In fact, the IT900 chip design incorporates an IT700 and IT900 PHY.

What is the maximum range for a single hop communication using IT900A?

The IT900A signal can run for several kilometers under ideal power line conditions. When the power line conditions are not ideal and the modem ‘suffers’ from heavy load and noises, the distance will be shorter but will still provide full connectivity (communication between two nodes) in standard size houses.

What is the modem's performance in terms of SNR and Dynamic range?

The IT900A provides very high immunity to various types of interference as it can operate at negative SNR levels. The minimal SNR level for CW interference (narrow band) is -30dB and for AWGN (White Noise) interference, the modem can operate at -7dB SNR. The IT900A modem also provides a wide dynamic range level of over 100dB.

Can two modems communicate if they are located on different phases? Is a phase coupler required?

Communication between different phases can exist due to inductance between the phases. Due to the robustness and the ability to perform communication in negative SNR and bad power line conditions, on standard size houses with normal power line conditions, IT900A can perform cross-phase communication with no need for external phase coupling.

When trying to communicate over “long distances” and over different phases (i.e modem X located on floor 1 plugged to phase 1 and modem Y located on floor 5 plugged to phase 2), there is a possibility that the modems will not overcome both the distance and cross-phasing. In this case you might need to use an external phase-coupler.

Does the modem work even when there is no power on the lines?

Yes. The modem does not require the AC power in order to perform communication. In fact, if there is no power on the lines the communication

Is it possible to implement an application inside IT900A (one chip solution)?

Yes. The Open Architecture version of IT900A enables a single chip solution using API.

Do you have reference designs?

Yes. Yitran provides full a reference design for a complete modem.
Alternatively, Yitran also provides a ready to use PIM (Plug in Module) that incorporates the IT900A and AFE.
