AUSTIN, Texas -- Freescale Semiconductor, Inc., a whollyowned subsidiary of Motorola, Inc. (NYSE:MOT), has unveiled the industry'sfirst system-on-chip (SoC) solution for broadband passive optical networking(B-PON). Freescale's advanced SoC device-the MPC8340BPON-integratesFreescale's e300 core (a PowerPC® processor core design), a B-PON mediaaccess controller (MAC), Ethernet MACs, and a clock and data recovery (CDR)unit on the same chip.

The MPC8340BPON provides an integrated solution for internet protocol (IP)services designed to minimize system-level cost through silicon integrationand reduction of the number of discrete memories required by optical networktermination (ONT) systems. Freescale's standards-based approach alsosupports end-to-end interoperability for applications such as massdeployment of fiber to the premises (FTTx) networks in Japan and othercountries deploying IP-based services.

"We currently use Freescale's MC92701 B-PON device with a PowerQUICC IITprocessor. Combining B-PON functionality from the MC92701 with Ethernet MACsand a processor platform is ideal for today's cost-sensitive market," saidMotoyuki Nakamure, General Manager of the Communication Networks Center atMitsubishi Electric Corporation. "Using a single-chip B-PON SoC reducessilicon cost, and therefore the bill of materials, for optical networktermination at the subscriber's premises. Ultimately, Freescale's integratedapproach to B-PON silicon will help original equipment manufacturers andservice providers broadly deploy fiber to the home in the Japan market at anattractive cost structure."
