Freescale integrates BPON chip

Freescale Semiconductor Inc. has combined a PowerPC processor core with its broadband passive-optical-networking (BPON) technology to create an integrated controller for Ethernet-only connections.

Motorola Inc.'s Freescale subsidiary has combined the capabilities of those two chips into the MPC8340BPO to aid carriers in Japan and the United States looking to deliver low-cost Ethernet-only services over PON channels.

Targeted at customer-premises equipment designs, the chip provides the same PON subsystem as Motorola's MC92701 controller. But Freescale has also integrated an e500 processor core supported by 32KB of instruction cache and 32KB of data cache. "The e300 processor handles control tasks on the chip," said Niket Jindal, business development and marketing manager at Freescale.

The MPC8340BPON offers two 10/100 Ethernet lines that are coupled with two AAL5 engines. Traffic is received from customer equipment through the 10/100 interfaces. The AAL5 engines are then used to convert the traffic into an asynchronous transfer mode stream that can be sent out over a BPON network.

Freescale said it plans to start sampling the chip during the fourth quarter.
