HXT8204-DNG

Overview

The HXT8204-DNG is a four-channel VCSEL driver array designed for optical transmitter modules. It operates at data rates up to 16 Gbps per channel with a maximum modulation current of 10 mA and average current of 10 mA. The device consumes 113 mW per channel while delivering 5 mA average and modulation currents. It features a 2-wire interface for control and supports symmetric pad design for module flexibility. The component is compliant with QSFP MSA standards and integrates CML input, laser driver, drive control, and supervision functions within a single silicon die.

Feature Summary

• Integrates complete digital-to-optical conversion including CML input, laser driver, and supervision
• Supports common cathode and isolated VCSEL arrays with flexible 2-wire interface control
• Delivers up to 10 mA average and modulation currents with low power consumption
• Complies with QSFP MSA standards for compact module assembly

Applications

• QSFP form factor optical transceiver modules
• High-speed data center interconnects
• Telecommunications transmission equipment

Procurement Notes

Verify the specific suffix DNG against official Renesas documentation to confirm package type and temperature range. Ensure compatibility with target VCSEL arrays regarding common cathode or isolated configurations. Confirm that the 2-wire interface logic levels match the system controller requirements. Validate that the 113 mW per channel power dissipation fits within the thermal design limits of the intended optical module enclosure.

Selection Notes

Select this component when designing high-density optical links requiring integrated laser driving and supervision. It is suitable for applications needing up to 10 mA drive current with low power consumption. Consider the symmetric pad design for layout flexibility. Ensure the host system supports the required 2-wire interface protocol for configuration and monitoring.

Part Context

The HXT8204 belongs to Renesas' family of Optical Receiver Transmitter Array (ORTA) products. It is part of a chipset solution often paired with compatible receivers like the HXR series for parallel optical links. The device utilizes standard silicon technology to enable cost-effective and compact assemblies for telecom and datacom markets.

Replacement Considerations

Consult official Renesas documentation for qualified substitutes. Verify pinout and electrical specifications match before substitution.
