ST Micro joins pincer movement on MoCA's Entropic

We mentioned a few months ago that ST Micro was about to put MoCA into its set top chips and this week it put out its announcement. This now further undermines the single source approach that MoCA has had until now, where Entropic was the sole chip supplier for that market.

Broadcom was the first to add MoCA to its existing set top SoC chips, but it announced that in 2009 and has clearly struggled with the technology. Entropic will tell you that it is ready with MoCA 2.0 chips while both ST Micro and Broadcom are struggling with MoCA 1.1, and we're pretty sure they it's right. But it's tough to continue for Entropic to make the volume of revenue out on the frontier of the technology, although margins there are usually higher.

Broadcom and ST Micro make up the great bulk of set top chips used around the western world and the addition of MoCA into the chips themselves will immediately halve the market for MoCA 1.1 for Entropic, limiting it to the TV sets and other non-set top devices out there which must talks to these set top chips.

STMicroelectronics said this week it didn't just have the chip but it had secured MoCA certification for its STi7108M MoCA 1.1 compliant HD-video decoder. This chip family is used as the basis for many set tops and DVRs.

MoCA uses QAM modulation on thousands of OFDM sub-carriers, but also adds complex bit loading algorithms, so that for each carrier a calculation can be done about how many bits it can deliver given its specific carrier to noise ratio, dynamically changing over time.

Both MoCA and MoCA 2.0 operate above 500 MHz and MoCA 2.0 goes up to 1650 MHz , which allows multiple MoCA networks to find frequencies alongside existing cable services. It sounds like a complex piece of silicon even in version 1.1 , which is why it has taken so long for it to arrive at Broadcom and ST Micro despite MoCA chips shipping in tens of millions.

Entropic will begin installing MoCA 2.0 chips in first quarter of 2012 so almost exactly as ST begins to ship this part into devices. MoCA 1.0 operates at around 175 Mbps, and the new MoCA 2.0 will deliver 400 Mbps in a single 100 MHz channel, double that to 800 Mbps in two bonded MoCA channels, with an extra 20% throughput when it operates in Turbo mode, so 500 Mbps and 1 Gbps.

"STMicroelectronics' entrance is a welcome addition to the connected home and supports growing demand for a highly reliable backbone," said Charles Cerino, MoCA President.

Set-top boxes featuring the MoCA-certified STi7108M can be added to a home network simply by connecting to the coaxial wall socket. As a high-end chip, the STi7108M offers advanced functions such as dual application processors providing 3D TV capability, a high-performance ARM graphics engine capable of supporting 3D gaming and advanced program guides, and ST's Faroudja video processing, the company said. Samples of the STi7108M are available now.
