Cortina Systems 100-Gbps ASSP targets converged OTN and Ethernet

Building on its introduction of the CS604x devices for 40-Gbps applications, communications semiconductor vendor Cortina Systems, Inc. has moved to 100-Gbps support via the new CS605x family of integrated transport processors.

Building on its introduction of the CS604x devices for 40-Gbps applications, communications semiconductor vendor Cortina Systems, Inc. has moved to 100-Gbps support via the new CS605x family of integrated transport processors. The new application-specific standard product (ASSP) family supports both Ethernet and Optical Transport Network (OTN) for platforms that transport and aggregate 10-Gbps, 40-Gbps, and 100-Gbps packet traffic.

According to Alex Afshar, product line manager, transport products at Cortina, the company sees the new CS605x family as a good fit for a variety of platform designs, including those targeted at data centers, Carrier Ethernet, core and edge router, DWDM, and packet-optical transport applications where high-speed and support for either Ethernet or OTN is required – and particularly where both play a role.

Elements of the family are compatible with both multi-lane Ethernet and coherent-enabled modules. Afshar says the company already has design wins in both areas.

The devices feature Cortina’s proprietary high-gain forward error correction (HG-FEC) technology, which offers 9.4-dB gain at 7% overhead. The three devices in the family consume between 10 and 12 W, Afshar says.

The CS605x line -- which includes the CS6051/53 (for full-featured aggregation and mapping; the CS6053 doesn’t have the HG-FEC), CS6052 for Ethernet and OTN mapping, and CS6054 for those who only need 40- and 100-Gigabit Ethernet (100GbE) support -- offers the following additional features:

  • 100GbE and 3x40GbE PCS/MAC termination with performance monitoring and networking support
  • Support for IEEE 1588v2 Transparent Clock mode, as defined in IEEE P1588D2.2
  • Integrated jitter attenuation and clean up PLLs
  • Direct interface to 100G and 40G optical modules supporting OTL4.10, CAUI, OTL3.4, and XLAUI interfaces
  • A 120G-capable Interlaken packet interface to NPUs, TMs and FPGAs

The CS605x family has been sampling since October. They should be available in production volumes sometime in the first half of 2012.
