HXR6112-DNT

Overview

The HXR6112-DNT is a twelve-channel linear transimpedance amplifier (TIA) array manufactured by Renesas Electronics Corporation. Designed for high-speed optical receiver applications, this device operates at data rates up to 16 Gbps per channel. It integrates the TIA pre-amplifier and limiting post-amplifier stages within a single silicon germanium (SiGe) component powered by a 3.3V supply. The part is supplied as an unencapsulated die in wafer form, suitable for integration into parallel optical link modules. The operational temperature range extends from 0°C to 85°C.

Feature Summary

• Integrates twelve independent optical channels with combined pre-amplification and limiting amplification functions
• Utilizes silicon germanium technology for high-speed signal processing capabilities
• Features a versatile CML output stage compatible with standard digital logic interfaces

Applications

• CXP optical module implementations
• 100 Gigabit Ethernet SR10 transceivers
• 164G FDR InfiniBand interconnects

Procurement Notes

Verify the specific ordering suffix and revision level against the manufacturer's latest product change notifications before finalizing procurement. Confirm that the wafer-level packaging meets the assembly requirements of the target module design. Ensure compliance with RoHS directives and check for any recent lead-free category updates or material declarations provided in the official documentation.

Selection Notes

Select this component when designing parallel optical links requiring twelve channels with integrated limiting amplification. Verify compatibility with the intended PIN detector array or discrete photodetectors. Ensure the system power budget accommodates the 3.3V supply requirement and that the thermal management strategy supports the specified operating temperature range for the application environment.

Part Context

This device belongs to the Optical Receiver Transmitter Array (ORTA) product family targeted at the parallel optical links market. It is designed to work in conjunction with PIN detector arrays to create high-capacity, high-availability optical links for datacom applications. The architecture simplifies module design by combining multiple analog front-end functions into a single integrated circuit.

Replacement Considerations

Consult the manufacturer's product advisory documents for confirmed substitute part numbers or alternative devices within the ORTA family. Verify functional equivalence regarding channel count, data rate, and interface compatibility before considering any cross-references.
