Freescale Semiconductor has developed a cost-effective, highly integrated solution designed to help lower costs for carriers and spur adoption of gigabit passive optical network (GPON) equipment in markets worldwide.

Built on third generation Freescale PON technology, the MSC7104 is a cost reduced version of the MSC7120 device that has been deployed in large volumes worldwide. It features interoperability with many of the world's top carriers.

"We have combined proven technologies and production-ready enablement options in the MSC7104 to take broadband data delivery over optical fiber technology into cost sensitive markets. We intend to spur adoption of GPON technology by creating cost-effective entry points into the market," said Nikolay Guenov, portfolio manager for Freescale's networking systems division.

The MSC7104 integrates data path engine and Power Architecture technologies to provide high data forwarding throughput rates for the delivery of video and data broadband content to homes and small businesses. The device supports the G.984 GPON Encapsulation Mode protocol and is compliant with ITU-T standards.

For carriers, GPON technology supports the convergence of IP over optical networks, offering connection speeds engineered to be much higher than today's DSL- or DOCSIS-based networks. It is a key enabler for bandwidth-hungry applications such as HDTV and Video on Demand.

"Broad scale, global adoption of GPON technology will be largely dependent on the availability of cost-effective solutions for manufacturers, carriers and consumers alike," said Aileen Arcilla, senior analyst for IDC's Semiconductor Team. "Reducing the cost of GPON deployment is especially important in greenfield markets such as the Asia-Pacific region where the potential for mass adoption is high."

MSC7104 tools, software
The MSC7104 combines the high-speed networking capabilities of the PowerQUICC II Pro platform featuring a Freescale e300 Power Architecture technology core and delivers over 8.5Gbit/s peak I/O throughput. The GPON media access controller and Freescale's hardwired packet engine are designed to achieve Gigabit wire rate packet forwarding. The integrated OMI/CDR supports 2.4Gbit/s downstream/1.2Gbit/s full GPON rates. Dual 10/100/1000 Ethernet MACs support GMII, RGMII and MII modes and IEEE 802.1p QoS. In addition, the MSC7104 includes a 280MHz/32bit DDR2 memory controller.

Development tools, hardware platforms, software building blocks and application specific software solutions are available for the MSC7104. The software includes Linux OS support for the Power Architecture core and a variety of applications software including GPON software stacks.

A software reference design is available from OpenCon systems. The solution's software package includes user applications and management modules, an OMCI stack and APIs that interface to the Freescale MSC7104. The package also enables communication between the GPON CPE and the central office at the service layer thereby enabling the central office to seamlessly manage and control the data flow to and from the subscriber ONTs. The reference design is expected to prove appeal to Asia-Pacific ODM customers looking to enter broadband-over-fiber markets quickly and with relatively low investment levels. Deployment of fiber-based network technologies is gaining momentum in highly populated areas of Asia.

Freescale is sampling the MSC7104 to alpha customers in Q3 08. It is offered in a 456-pin PBGA package. Pricing starts at a suggested resale price of $12 for 10,000-unit quantities.
