Title Type Date
HXT14450 / HXR14450 Integrated 56 Gb/s Optical CDR / Retimers

Watch an overview of the industry’s first CMOS-based PAM4 CDR solutions, HXT14450 50G/lane PAM4 integrated CDR with VCSEL driver and HXR14450 TIA designed for 200 Gb/s and 400 Gb/s transceivers and AOCs (active optical cables) in datacenters. The series features significantly lower power and smaller size compared with traditional DSP solutions, as well as higher integration – including an integrated MCU – to further simplify system design.
