Laser Drivers
GigPeak Inc. (Acquired by IDT)
GigOptix Inc. offers single- and quad-channel limiting 28-Gb/s direct modulated laser driver chipsets for data center and cloud computing applications.
The single-channel HXT42100 and quad-channel HXT42400 drivers respectively enable lower-power 28-Gb/s SFP28+ and 100-Gb/s QSFP28+ Ethernet modules, or active optical cable systems. The drivers also provide 32- and 128-GFC (generic flow control) support, respectively, for fiber channel storage systems.
Both drivers support low-voltage supply operation as low as 2.5 V with modulation and bias currents of 50 mA, and can be driven with supply voltages up to 3.3 V.
