Overview
The NT22030-GRP6 is a CMOS high-speed LED driver designed for Plastic Optical Fiber (POF) applications, supporting data rates such as Fast Ethernet and 250 Mbps. It delivers up to 25 mA of modulation current with total current consumption of less than 14.75 mA, excluding drive current. The device operates on a 3.3 V supply and features differential LVDS input with AC-coupled CML compatibility. It includes mask-programmed on-chip temperature compensation and pulse width adjustment, ensuring reliable operation at junction temperatures up to 125 °C.
Feature Summary
- Integrates mask-programmed on-chip temperature compensation and pulse width adjustment for stable LED performance.
- Accepts differential LVDS inputs with AC-coupled CML compatibility for flexible interface integration.
- Fabricated in a standard mixed-signal CMOS process optimized for high-volume production.
Applications
- Fast Ethernet over Plastic Optical Fiber
- 250 Mbps POF communication links
Procurement Notes
Verify the specific suffix 'GRP6' against official Semtech documentation to confirm exact binning or testing parameters. Ensure design-in requirements match the bare die format and 3.3 V supply constraints. Confirm that the mask-programmed settings align with the target application's thermal and timing specifications before finalizing procurement.
Selection Notes
Select this component for POF systems requiring low power consumption and integrated thermal management. The absence of external components within the frequency offset tolerance range simplifies board layout. Ensure the host system supports the required LVDS/CML input signaling and can accommodate the bare die packaging solution.
Part Context
The NT22030 belongs to Semtech’s laser drivers and transceivers portfolio, specifically targeting cost-effective optical interconnects. It complements other devices like the NT22031 RCLED driver within the same family, addressing different light source technologies for similar POF data rates.
Replacement Considerations
The NT22031 is an officially documented related part within the same product line, serving as a driver for RCLEDs rather than standard LEDs. Verify functional equivalence regarding pinout and electrical characteristics if considering cross-model substitution.
