Overview
The HXT42100-DNG is a low-power Direct Modulated Laser (DML) driver designed for CLR and LR optical applications. It supports data rates up to 28 Gbps and optical reach up to 10 km. The device handles complete digital-to-optical conversion, including CML input stage with equalization, laser driver bias current (Ibias), and modulation current (Imod) drive control and supervision. It is designed for direct DC-coupled anode drive of DFB laser diodes to enable cost-effective and compact assemblies.
Feature Summary
- Supports modulation and bias currents up to 60 mA peak-to-peak
- Features programmable input equalization and pulse width adjustment
- Integrates temperature sensor with user-selectable mask control interrupts
- Complies with QSFP MSA standards for module design flexibility
Applications
- CLR optical applications
- LR optical applications
- QSFP module designs
- DFB laser diode drive assemblies
Procurement Notes
Verify the specific suffix against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing system power supplies and interface requirements before procurement. Confirm availability status as product lifecycles may change.
Selection Notes
Select this component for designs requiring a single-channel DML driver supporting up to 28 Gbps. It is suitable for applications needing integrated bias and modulation current control with programmable equalization. Consider its DC-coupled anode drive capability for simplified circuit design in compact optical modules.
Part Context
This part belongs to the HXT series of laser drivers from Renesas Electronics.
