Silicon & Software Systems Ltd (S3) has taped out and received silicon from the 65nm node version of its licensable mixed-signal IP. This is already being designed in by major developers of SoCs targeted at wireless and multimedia applications.

"I can't name the companies who are designing in our latest available node technology, but the applications they are targeting are mobile WiMAX where it is important to handle multiple channels," Bob Tait, marketing director of S3's consumer silicon business unit told EE Times Europe.

The first products that use the latest IP cores?which includes AFEs, ADCs, DACs and associated PLLs?should be available early next year, Tait added.

As well as mobile WiMAX, the IP is expected to find use in WLAN chips, different flavours of mobile TV silicon, and for high-definition video and powerline communications.

S3 has demonstrated the cores at the FSA Supplier's Expo in California, U.S.

"Some of the companies that are using the 65nm mixed signal converter IP signed up even before we launched the product, on the back of using similar technology developed for 90nm process technology," Tait said.

S3 is taping out solutions, integrating IP into single-chip systems, leveraging extensive design experience and producing more than 35 SoC designs at the 90nm and 65nm process technology nodes.

Tait revealed that one of these companies, at the 90nm node, is Abilis Systems, a subsidiary of security and digital rights management company Kudelski SA originally formed by former Motorola SPS engineers. The company demonstrated and said it started shipping a single-chip DVB-T mobile DTV (MDTV) receiver using IP from S3, at the recent International Broadcasting Convention in Amsterdam.

The AS-102 from Abilis is targeted for use in personal portable devices and combines a multiband RF tuner with a demodulator, memory and a USB 2.0 interface and measures 9-mm by 9-mm. The chip requires no active RF components to complete a receiver circuit and consumes 350-mW.

S3 has also been working for many years with another developer and supplier of DVB-T chips for digital radio and mobile TV, Frontier Silicon.
