FIN1031M

Overview

The FIN1031M is a quad driver designed for high-speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. It translates LVTTL signal levels to LVDS levels with a typical differential output swing of 350mV, providing low EMI and ultra-low power dissipation at high frequencies. The device operates on a 3.0V to 3.6V supply voltage and supports data rates greater than 400Mb/s. Key electrical parameters include a maximum propagation delay of 2.0ns, a maximum differential pulse skew of 0.4ns, and a typical power supply current of 5mA under no-load conditions. It meets or exceeds the TIA/EIA-644 LVDS standard.

Feature Summary

• Translates LVTTL input signals to LVDS output levels for high-speed data transfer
• Provides power-off protection to prevent excessive current draw when VCC is off
• Pin-compatible with equivalent RS-422 and LVPECL devices for design flexibility

Applications

• High-speed clock distribution networks
• Data bus transmission systems
• Point-to-point serial communication links

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel availability. The base part number indicates a SOIC-16 package. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the component lifecycle status aligns with long-term production requirements.

Selection Notes

Select this component for applications requiring translation between LVTTL logic levels and LVDS signaling standards. Consider the 16-lead SOIC package for space-constrained designs. Verify that the system operating temperature range falls within the specified -40°C to +85°C limits. Ensure the load resistance matches the 100Ω differential termination requirement for proper signal integrity.

Part Context

The FIN1031 belongs to the Fairchild Semiconductor LVDS driver family. It is functionally paired with companion receivers such as the FIN1032. The 'M' suffix specifically denotes the 16-Lead Small Outline Integrated Circuit (SOIC) package variant, distinguishing it from the TSSOP version.

Replacement Considerations

Check for pin-compatible equivalents in the RS-422 and LVPECL categories. Verify if other LVDS drivers from the same manufacturer offer similar propagation delays and power consumption profiles.
