Semtech’s optical networking product platforms provide high-performance signal integrity for optical module solutions used by leading companies in hyperscale data center applications, enterprise networking, wireless infrastructure, including 5G fronthaul, 5G midhaul, and passive optical network/Fiber-to-the-X markets.

Semtech offer one of the industry’s most innovative optical, analog and mixed-signal transceiver IC portfolios, supporting all main optical communications applications, such as:

Data center networking: Ethernet (both NRZ and PAM4), Fibre Channel, InfiniBand®

Wireless fronthaul: Common Public Radio Interface (CPRI), eCPRI

Fiber to the X (OLT and ONU): Passive Optical Networks (PON) such as EPON, GPON, 10GPON, XGPON, XGSPON

Optical transport: Synchronous Optical Networking (SONET)/SDH, OTN

Consumer/Industrial: PCI Express® (PCIe), HDMI

Semtech’s industry-leading optical IC platforms include:

ClearEdge® CDRs (clock and data recovery) with low-power, reference-free technology

FiberEdge™ TIAs (transimpedance amplifiers) and laser drivers

Tri-Edge™ CDRs for analog PAM4 signal processing

PON-X™ TIAs and Combination drivers for 10G EPON and XGSPON OLTs and ONUs

Semtech’s ultra-low power, high-performance reference-free clock and data recovery (CDR) product line is anchored around our ClearEdge® CDRs for NRZ (non-return-to-zero) applications at 10Gbps, 16Gbps and 100Gbps, and our Tri-Edge™ CDRs for PAM4 applications at 200Gbps and 400Gbps. Based on our reference-free CDR architecture our ClearEdge and Tri-Edge products provide multi-lane signal conditioners with best in class sensitivity, output jitter and jitter tolerance, that can also be monolithically integrated with laser drivers and transimpedance amplifiers (TIAs) to provide compact, high-performance solutions.

Semtech’s Laser Driver and Transceiver IC family includes superior laser drivers and receivers integrated for low cost, high performance optical communications systems. Semtech’s technology platform utilizes both Silicon Germanium (SiGe) BiCMOS and pure CMOS designes based on performance and cost requirements. Semtech's laser driver and transceiver solutions range from 125Mbps to 100Gbps and beyond and enable NRZ, Burst Mode and PAM4 signaling. Key applications and markets include Data Centers, Access and PON and Wireless infrastructure.

Semtech’s extended selection of limiting post amplifiers is completely integrated with Silicon Germanium (SiGE) BiCMOS and pure CMOS. These limiting amplifiers are designed for fiber optic transceiver applications and fast Ethernet fiber optic applications. Semtech's limiting post amplifier for fiber optic applications is the lowest cost and lowest power solution for optical network applications at data rates up to 11.3 Gbps.

Elite receiver optical sub-assemblies (ROSAs) are engineered based on patented Semtech Rchip technology. Semtech's complete line of PIN and APD ROSA products spans 1310nm nanometer (nm) to 1550nm including limiting, linear and automatic gain control (AGC) functionality. Semtech PIN ROSAs operate at +3.3V±10% and from -40°C to 85°C, with highly accurate RSSI functionality and industry best dynamic range. The ROSA products feature patented Rchip packaging in a fully compliant SC or LC type optical subassembly and are available with optional flex circuits. 

Semtech’s multi-channel signal conditioners enhance the reach and robustness of high-speed serial links by compensating for transmission losses and re-setting the crosstalk and jitter budgets. Semtech's conditioners offer a high level of integration, a small footprint, a full portfolio, and low power. The backplane and linecard signal conditioners are ideal for small form factor modules or dense backplane/linecard applications.

Transimpedance Amplifiers (TIAs) Semtech offers a broad portfolio of fully integrated BiCMOS and pure CMOS transimpedance amplifiers (TIAs) providing wideband, low noise pre-amplification of a current signal from a PIN or APD photodetectors. Semtech's TIAs offer best-in-class performance in limiting, linear or automatic gain control versions for use in high-performance optical receivers operating from 155Mbps to 100Gbps. They include fully integrated on-chip de-coupling for low cost and best performance and can be utilized in NRZ, Burst Mode and PAM4 signaling systems. Key applications and markets include Data Centers, Access and PON and Wireless infrastructure.
