Features the fastest lock time of 10.8 nanoseconds among mid-range FPGAs for PONs

Microchip Technology, Inc., via its Microsemi Corp. subsidiary,
recently launched the new PolarFire field programmable gate array (FPGA) burst
mode receiver (BMR), which the company boasts is the first FPGA for 10G passive
optical network (PON) implementation in small form factor pluggable (SFP) and
10 Gb SFP (XFP) footprints. The new PolarFire FPGA BMR solution features the fastest lock times (just 10.8
nanoseconds) on the market among mid-range FPGAs for PONs, according to the

optical line terminal (OLT) implementations in central offices typically
feature large port counts in large chassis configurations, which take up space
and consume lots of power. The new BMR solution allows developers to assemble
OLTs in smaller form factor modules while consuming the lowest power in extreme
thermal environments, said Microchip.

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,” according to 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 SY88029L burst amplifier, the first limiting amplifier in the
industry to be fully compliant with XGSPON and NGPON2 timing requirements,
according to Microchip, delivers a burst mode signal detect time of less than 7

Microchip provides
designers with a suite of development tools to streamline the design process
including a hardware kit, reference design and Microchip’s Libero Integrated
Design Environment (IDE) software.

PolarFire FPGA 10G PON BMR solution is currently available and free to
subscribers of Microchip’s Libero design suite.
