Semtech Reaffirms EPON Leadership with Addition of Two Key Products

FiberEdge™ driving market by offering improved technical and
commercial performance

SAN DIEGO–(BUSINESS WIRE)–OFC 2019 – Semtech Corporation (Nasdaq: SMTC), a leading supplier
of high performance analog and mixed-signal semiconductors and advanced
algorithms, today announced the newest additions to FiberEdge™ including
a combo chip (GN7154) and a multi-rate burst mode Transimpedance
Amplifier (TIA) (GN7056) for 10G EPON Optical Line Terminals (OLTs).

“The upsurge in the 10G EPON market is expected to continue and we
believe these products will help drive this growth,” said Dr. Timothy
Vang, Vice President of Marketing and Applications for Semtech’s Signal
Integrity Products Group. “Our engineering team has produced another
unique chipset that delivers higher performance and enables lower
manufacturing costs through further integration.”

The GN7154 is a fully bidirectional device that supports both 1G and 10G
EPON. The transmit data path features Semtech’s proven 10G EML driver
with ClearEdge® CDR referenceless technology to effectively reset the
path jitter budget. Tx path optimization can be accomplished via an I2C
programmable PLL loop bandwidth control and a variety of jitter filter
modes. The EML driver includes eye-shaping features and an automatic
power control loop to deliver best-in-class transmit eye quality. The
burst mode receive data path includes two separate limiting amplifiers,
one for 1G EPON and the other for 10G EPON with a fast Burst Mode Signal
Detect function. The Rx path outputs 10G data at CML levels, while the
1G Rx output is available at CML or LVPECL levels depending on the
device version.

The GN7056 is Semtech’s next-generation high sensitivity Burst Mode TIA
designed for 10G EPON OLT applications. The device features a fast
automatic gain control loop to enable high dynamic range in burst mode
applications. The GN7056 is offered in die form, supports industrial
temperature range and uses a single 3.3V power supply.
