Mindspeed enables high-density 100 Gigabit systems with family of lowest-power 28G clock and data recovery devices

OFC/NFOEC 2013, USA: -Mindspeed Technologies Inc. has announced the industry’s lowest-power clock and data recovery (CDR) devices capable of supporting data rates up to 28 gigabits per second (Gbps).

Low power dissipation is a critical requirement for small form factor interconnects for the 100 Gigabit Ethernet, InfiniBand and optical transport systems enabling port densities that the industry must achieve in order to handle increasing Internet traffic and escalating online video content demand.

Mindspeed’s four channel CDRs support data rates required for multiple standards including 100G Ethernet, InfiniBand Enhanced Data Rate (EDR), 32G Fibre Channel and Optical Transport Network (OTU-4). The low-power solution enables next-generation optical and copper module form factors, such as CFP-2, CFP-4 and Quad Small Form-Factor Pluggable (QSFP).

Mindspeed’s CDRs integrate key features, such as an input equalizer and output de-emphasis to optimize link performance and support line card retiming applications as well as loopback for system level diagnostics. The devices are reference-free, eliminating the need for reference crystal oscillators thus reducing the number of components and cost required to implement a retiming function.

The devices include input equalization circuitry to support lossy channels and support a wide output amplitude range to seamlessly interoperate with optical assemblies.
