Sigma's extremely stealthy HomePlug AV chip is now the fourth chip, after Atheros, Gigle, and SPiDCOM, which is certified by HomePlug for compliance to the HomePlug AV specification.
Before reporting this, a sceptical HAN Fan spent time to confirm Sigma's press release as they were MIA from the recent HomePlug Interop Plugfest. Also surprising were the VP claim to have "more than a dozen companies to continue building products with the company's chips" before the chip passed compliance and before any interop tests have been done--gutsy companies.
HAN Fan is even looking more forward to the price war that will come from the competition of multi-sourced standards based products. She now thinks a feature war would be nice too.
