Freescale Semiconductor MSC7104 Block Diagram

The MSC7104 Gigabit Passive Optical Network (GPON) device is an advanced, cost-effective, highly integrated solution for broadband passive optical network termination (ONT) applications. It is designed to enable broadband data delivery over optical fiber technology in cost sensitive markets. Built on third generation Freescale PON technology, the MSC7104 is a cost reduced version of the MSC7120 device. 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 (GEM) protocol and is compliant with ITU-T standards.

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 8.5 Gbps peak I/O throughput. The GPON media access controller (MAC) and Freescale's hardwired packet engine are designed to achieve Gigabit wire rate packet forwarding. The integrated OMI/CDR supports 2.4 Gbps downstream/1.2 Gbps 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 280 MHz/32-bit DDR2 memory controller.

Development tools, hardware platforms, software building blocks and application specific software solutions are available for the MSC7104. The software includes Linux operating system 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 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.
