Clock and data recovery devices support 28 Gbps speed

Mindspeed Technologies has unveiled low-power consuming and small size clock and data recovery (CDR) devices supporting data rates up to 28 gigabits per second (Gbps). Mindspeed's M37046 four-channel CDR supports data rates required for multiple standards, including 100G Ethernet, InfiniBand enhanced data rate (EDR), 32G Fibre Channel and optical transport network (OTU-4). M37046 features limiting amplifier with good input sensitivity, output de-emphasis to optimize link performance as well as test pattern generation and checking for system level diagnostics. The devices are reference-free, eliminating the need for reference crystal oscillators. Molex has built its retimed 100Gbps PSM4 zQSFP+ Active Optical Cable using Mindspeed's CDRs. "In the drive to increase bandwidth density on the front panel and the backplane, systems OEMs require small form-factor pluggable modules and small on board optical engines. These solutions will future proof customers' investments in networking infrastructure, but, at the same time the small form factor of these modules create a challenge for interconnect manufacturers to meet the footprint, power consumption and thermal constraints," said Adit Narasimha, director of active optics at Molex, Incorporated. "Molex's silicon photonics-based solutions and optical backplane in combination with Mindspeed's low power CDRs answer these market n...
