HXT5112A-DNT

Overview

The HXT5112A-DNT is a 12-channel VCSEL driver array designed for compact, low-power optical transmitter modules. It operates at data rates up to 16 Gbps per channel. The device delivers a maximum average current of 10 mA and a maximum modulation current of 10 mA, with a burn-in current capability of 15 mA. Power consumption is rated at 46 mW per channel. It supports CML inputs and includes drive control and supervision functions.

Feature Summary

• Compatible with common cathode and isolated VCSEL arrays
• Features a 2-wire interface control and symmetric pad design for module flexibility
• Handles complete digital-to-optical conversion including laser driver and supervision

Applications

• InfiniBand QDR/FDR compliant optical links
• 100G Base-SR10 compliant optical links
• Compact optical transmitter modules

Procurement Notes

Verify the specific suffix DNT indicates the wafer package option when ordering. Confirm the active status and lead-free compliance (e3 Sn) through official Renesas channels. Ensure the operating temperature range of 0 to 70°C aligns with system requirements before procurement.

Selection Notes

Select this component for applications requiring high channel density in a small form factor. It is suitable for systems needing InfiniBand or 100G Ethernet compliance. Consider the 16 Gbps speed limit and 10 mA current capabilities against the specific VCSEL array requirements.

Part Context

This part belongs to the HXT series of VCSEL drivers from Renesas. It shares functional similarities with the HXT6112 but offers a different channel count and package configuration. The series utilizes standard silicon technology for cost-effective assemblies.

Replacement Considerations

The HXT6112 is a related product within the same family. Verify pinout compatibility and channel count differences before substitution. No other direct public substitutes are confirmed.
