Metro-Ethernet Framer/Mapper/PHY chip aids move to 10 GbE — AMCC

In telecommunication systems, the move is on from SONET/SDH to 10 GbE/Optical Transport Networks (OTN). The Pemaquid 10-Gigabit Metro-Ethernet Framer/Mapper/PHY device (S19258) makes that move much easier and does so with a single-chip cost of around $100 in volume instead of the previous multichip solutions for $900.

Targeted at carrier Ethernet and metro WDM transport networks, the chip provides a direct connection between 10G MACs, network processors, or 10-GbE switches, and XFP/SFP+ optical modules. A single Pemaquid can take the place of up to three devices: an FEC/Framer/Mapper, an SFI4.1 to Serial 10G Physical layer, and a bridge connecting the MAC to the Framer/Mapper, and with a power consumption of only 2.5 W.

The chip’s integrated FRACn synthesizer requires only a low-cost external reference oscillator to enable support for all 10G line rates. The IC supports seven 10-GbE mapping modes, provides digital forward error correction and analog electronic dispersion compensation functions, and comes in a small 19 x 19-mm package.
