Semtech Announces Initial Production of Highly-Integrated ClearEdge® CDR

New ClearEdge CDR provides industry’s lowest power swing of 790mW at maximum 1.5VppSE

CAMARILLO, Calif., March 12, 2018 – Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, today announced initial production of its fully integrated quad 28G ClearEdge® CDR with single-ended EML laser driver. It offers the industry’s lowest power at only 790mW at maximum 1.5VppSE swing in a 6mm x 5mm package with integrated bias-T passive components.

The ClearEdge CDR with single-ended EML laser driver (GN2106S) enables best-in-class performance with EML based TOSAs while solving the challenge of real estate in QSFP28 designs.

“Semtech’s 100G ClearEdge CDR and EML driver solution delivers lower power and more integration of components for EML-based LR4 and ER4 modules,” said Imran Sherazi, Vice President of Marketing and Applications for Semtech’s Signal Integrity Products Group. “The new quad 28G ClearEdge CDR enables our customers to achieve the Industry’s highest performance solutions with our new lower power and highly-integrated offering.”

Semtech will privately demonstrate the new solutions in its OFC booth (#1322) at the San Diego Convention Center.
