SPC300
"No-Limits" HomePlug AV SoC
Use case:
SPiDCOM SPC300 HomePlug AV SoC has been designed by SPiDCOM engineers.
It’s main application scenario is Triple-Play whole house distribution.
ISP can take advantage of this powerful solution to make the Triple-Play connection between the IPTV home gateway and IPTV set-top box(es) using existing electrical wires.
To know more about this use-case, you can browse IPTV page.
End-users can also use SPC300 base products to connect digital set-top boxes, PVR, NAS, consoles for video games.

Main features:
SPC300 is based on an open dual core architecture:
The first processor is dedicated to the physical layer management and all real-time requirements. It enables the SPC300 SoC to adapt to the changes in the electrical power lines and to react accordingly in order to maintain the highest levels of performance.
The second processor, an ARM926, is dedicated to applications.
Main features of SPC300:
- Advanced dual-core architecture

MAC overview:
SPiDCOM provides partners Linux source bundles and the complete tool chain to develop and customize added-value applications (e.g. VLANs, a full IP stack, router, TR-069, SNMP, HTTP,...).
In addition, the multimedia and general purpose interfaces allow cost-effective solutions for HD/SD IPTV set-top boxes, home-gateways, DVRs, media centre PCs, whole house audio and VoIP. They also support traditional networking applications such as bridging to wireless 802.11 networks and xDLS/FTTH broadband.
Flexible QoS to ensure your QoE
To ensure efficient and reliable streaming of broadcast quality HD and SD video, the SPC300 implements both prioritised and parameterized QoS. Prioritised QoS is useful for efficient VoIP using CSMA/CA. Parameterized QoS is needed for guaranteed bandwidth reservation, latency/jitter control and effective error free delivery.
