描述
The HXC42400 is a uni-directional Quad Channel CDR / Retimer for retiming data rates from 25Gbps to 28.05Gbps. It is optimized for 100Gbps Ethernet, OIF CEI-28G-VSR and OTU-4 Optical Transport applications. The HXC42400 can be used in either direction of a transceiver module and can be adopted into QSFP28+, or CFP2/CFP4 modules because of its low 100mW per channel power dissipation. In Bypass operation, the HXC42400 supports legacy data rates up to 16Gbps.
Designed for direct DC-coupled anode drive of the DFB laser diode for cost-effective and compact assemblies. Available in FCBGA 5x5mm form.

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.
