Microsemi PolarFire FPGA burst mode receiver enables transceiver-sized 10G PON OLT designs

Microsemi Corp., a subsidiary of Microchip Technology Inc. (NASDAQ: MCHP), has released the PolarFire FPGA burst mode receiver (BMR) solution, which the company says enables the design of 10G PON optical line terminals (OLTs) in optical transceiver form factors. The company says its FPGA is the only product of its kind that can enable 10G PON OLT functions to fit in either an SFP or XFP optical module.

Microsemi Corp., a subsidiary of Microchip Technology Inc. (NASDAQ: MCHP), has released the PolarFire FPGA burst mode receiver (BMR) solution, which the company says enables the design of 10G PON optical line terminals (OLTs) in optical transceiver form factors. The company says its FPGA is the only product of its kind that can enable 10G PON OLT functions to fit in either an SFP or XFP optical module.

Microchip says PolarFire FPGA with BMR operates with very low power and in extreme thermal conditions. It features what the company asserts is the fastest lock times (10.8 nsec) available in mid-range FPGAs for PONs as well.

"The PolarFire FPGA BMR solution is a game changer for our clients designing 10G PON applications because it fundamentally changes the way they build, deploy, and maintain systems," said Shakeel Peera, vice president of FPGA marketing for Microchip's Programmable Solutions business unit. "The combination of PolarFire FPGAs and the new BMR technology enables designers to build unique, proprietary solutions that address the key challenges of reducing power consumption and heat dissipation of PON equipment, while delivering the small form factor their end customers are demanding to expand remote deployment choices for carriers."

Microchip and Microsemi supply the PolarFire FPGA 10G PON BMR capabilities with a suite of tools to ease application development. The tools include a reference design, Libero Integrated Design Environment (IDE) software, and a hardware kit. The function is free for current subscribers of Microchip's Libero design suite.

Microchip also supplies complementary silicon, such as the SY88029L burst mode limiting amplifier. The SY88029L has a burst mode signal detection time of less than 7 nsec and is fully compliant with XGS-PON and NG-PON2 timing requirements, the company says.
