HXT14450-DNU General Description

The HXT14450 is a quad-channel, low power, linear vertical-cavity surface-emitting laser (VCSEL) driver with an integrated clock and data recovery (CDR) unit. The chip is designed for MMF PMD Short-Reach applications that support 200G per port with a signaling rate up to 56Gbps PAM4 modulation. In conjunction with the HXR14450 – a quad-channel transimpedance amplifier (TIA) receiver with an integrated CDR, one can produce compact quad small form factor QSFP-type modules to serve high speed optical interconnects in data center applications.

The HXT14450 has a built-in adaptive linear equalizer and a decision-feedback equalizer (DFE), which can work in chip-to-module and chip-to-chip interconnects. The chipsets provide on-chip testability such as PRBS generator and error checker.
Designed for direct DC-coupled die with VCSEL or on-board optics (OBO) and with a small number of additional components for cost-effective and compact assemblies, this chipset enables lower power and compact modules for high density and high BW application in hyper-scale data center applications.
