Board wit Freescale's MSC7120 GPON chip

Freescale Semiconductor has released what it claims is the industry's first voice-enabled gigabit passive optical networking (GPON) SoC. The device is said to enable the delivery of rich digital content to the home and office via fiber.

The multicore MSC7120 integrates a Power Architecture CPU, a StarCore DSP and a data path engine to deliver a complete PON subsystem in a single device. It addresses the high data forwarding throughput requirements of several applications including the delivery of triple-play broadband services to the home or small business.

Fruit of collaboration
Freescale and GPON equipment supplier Alcatel-Lucent initiated joint development of the MSC7120 after the companies agreed in 2005 to collaborate on delivering compatible, interoperable and cost-effective GPON technology to the market.

GPON technology supports the convergence of IP over optical networks, offering connection speeds much higher than today's DSL- or DOCSIS-based networks. It is a key enabler for bandwidth-hungry triple-play applications such as HDTV and video-on-demand.

The MSC7120 combines the high channel voice density of Freescale's MSC711x DSP device with the high-speed networking capabilities of the PowerQUICC II Pro platform featuring Power Architecture technology, a GPON MAC and the company's packet engine, which achieves Gigabit wire rate packet forwarding. The device supports the G.984 GPON GEM protocol and is designed to be compliant with the ITU-T standards.

Development tools
Development tools, hardware platforms, software building blocks and application-specific software solutions for the MSC7120 are available. The software includes RTOS for the StarCore DSP and Power Architecture cores and a variety of applications software including DSP voice framework, signaling stacks and GPON software stacks.

Freescale is sampling the MSC7120 to alpha customers. It is offered in a 456-pin thermally enhanced PBGA package. Pricing information can be requested directly from the Freescale.
