Semtech Corp. has unveiled its multiplexer device supporting 100Gb/s ultra-long-haul network applications. The SMI10022 is designed to support soft-decision forward error correction (FEC), which enables a significant improvement in optical transmission reach for ultra-long-haul and submarine optical links, noted the company.

Designed in BiCMOS silicon germanium and using custom modern ceramic BGA (SMT) packaging technology, it provides high reliability, high performance and reduced cost, boasted Semtech.

Sameer Vuyyuru, vice president for Semtech's advanced communications group, stated that newer designs are leveraging the SMI10022's ability to support data ranges required for soft-decision FEC, which enables increased transmission reach. Vuyyuru also stressed the need to continue to offer the industry's most complete high performance product solutions for demanding 40 and 100 Gb/s long haul applications.

The SMI10022 is a 4x 32G output multiplexer with on-chip clock multiplier unit (CMU) and integrated precoder. The input data interface is user selectable 20-lane or 10-lane and compatible with CEI-6G/11G-MR. The device offers features such as data-to-data skew adjust, full- and half-rate high speed CML clock outputs and an on chip PRWS error checker and pattern generator.

While these products offer designers the benefit of significant board space savings, their small size and RoHS & WEEE compliance also contributes to energy conservation and hazardous waste reduction.

Engineering samples of the SMI10022 are available to limited customers and the device is scheduled to enter volume production by end of August.
