The VCSEL driver includes a limiter, an equalizer, a waveform shaping block with over- and undershoot control, an output driver, power-on reset circuitry, a 2-wire serial interface with a control logic block, a modulation current generator, a bias current generator with automatic power control loop, and more.
A monolithic laser resonator is used in a vertical-cavity surface-emitting laser, which emits light vertically to the semiconductor chip’s surface as opposed to edge-emitting laser diodes, which emit light from the chip’s edge.
The global VCSEL drivers market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
For 400G and 800G data centers, Semtech has released Fiber Edge Linear Vertical-Cavity Surface-Emitting Laser (VCSEL) Driver.
ECOC 2022— The GN1848, a brand-new addition to the Fiber Edge platform of PAM4 chipsets, is now immediately available, according to Semtech Corporation, a top global supplier of high-performance analogue and mixed-signal semiconductors and advanced algorithms.
The Fiber Edge GN1848 VCSEL driver, paired with our newly released Fiber Edge GN1816 transimpedance amplifier (TIA), can provide the high performance and low cost required by our customers in high-speed short reach multimode and active copper cable (AOC) applications, Semtech’s Fiber Edge multimode chipset’s compatibility extends the well-known Fiber Edge range and enables high-speed optical producers to more simply and quickly construct market-leading and affordable optical modules.
With configurable bias and modulation currents, the Fiber Edge GN1848 is a 56GBd quad low power, low cost, low noise, and industry leading linear VCSEL driver that enables interoperability with other VCSELs.
The Fiber Edge GN1848 is made for active optical cables and 400GBASE-SR4/VR4 and 800GBASE-SR8/VR8 PAM4 multimode optical transceivers (AOC).
Currently available as a wire-bondable bare die, the Fiber Edge GN1848 enables direct wire bonding to a quad channel 250 m pitch VCSEL without the use of a bias tee.
