Semtech announces 51-Gbps SerDes for ultra-long haul

Semiconductor supplier Semtech Corp. (NASDAQ: SMTC) has announced it will soon supply engineering samples of the SMI5026 and SMI5036, its 51-Gbps DQPSK multiplexer and demultiplexer chipset.

Semiconductor supplier Semtech Corp. (NASDAQ: SMTC) has announced it will soon supply engineering samples of the SMI5026 and SMI5036, its 51-Gbps DQPSK multiplexer and demultiplexer chipset. The SMI5026 and SMI5036 are designed to increase FEC overhead to improve optical transmission reach for ultra-long-haul and submarine optical networks.

Both devices are designed with a BiCMOS silicon germanium process and use custom ceramic BGA (SMT) packaging technologies that promote high reliability, high performance, and reduced costs, Semtech asserts. The SMI5026 multiplexer is also fully compatible to, and can be used in, high-data-rate BSPK-based coherent transmit designs.

“The SMI5026 and SMI5036 will enable us to target new submarine and ultra-long-haul links that are now being deployed around the world,” said Sameer Vuyyuru, vice president and general manager for Semtech’s Advanced Communication Product Group. “Carriers and system vendors can translate our market-leading 51.0-Gbps DQPSK data rate into FEC overhead to increase transmission reach and significantly reduce system costs.“

The SMI5026 is a 16:2 multiplexer with on-chip clock multiplier unit (CMU) and integrated DQPSK precoder. The input data and clock interface is compatible with OIFSFI5-01.0 and OIF-SxI5-01.0 standards. The device also features data-to-date skew adjust, full and half rate CML clock outputs, and an on-chip PRWS error checker and pattern generator.

The SMI5036 is a 2:16 dual clock and data recovery (CDR) demulitiplexer device with integrated DQPSK decoder. The output data and clock interface is compatible with OIFSFI5-01.0 and OIF-SxI5-01.0 standards. The device features independent CDR lock status indicators, a per channel adjustable threshold and sample clock phase, and an on-chip PRWS error checker and pattern generator.

Engineering samples of the SMI5026 and SMI5036 devices will be available after April 1, 2012, and the device is scheduled to enter volume production in the second quarter of 2012.
