FIN1031MTC

Overview

The FIN1031MTC 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 even at high frequencies. The device supports data rates greater than 400Mb/s and operates on a 3.3V power supply. Key electrical parameters include a maximum propagation delay of 2.0ns, a maximum differential pulse skew of 0.4ns, and a maximum frequency of 275MHz. It functions within an operating temperature range of -40°C to +85°C and is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP).

Feature Summary

• Translates LVTTL inputs to LVDS outputs for high-speed clock and data transfer.
• Provides power-off protection to prevent current leakage when the supply is off.
• Meets or exceeds the TIA/EIA-644 LVDS standard for compatibility.
• Pin-compatible with equivalent RS-422 and LVPECL devices.

Applications

• High-speed serial communication links.
• Clock distribution networks.
• Data bus interfaces requiring low electromagnetic interference.

Procurement Notes

Verify the specific package variant, as the FIN1031 series includes both SOIC and TSSOP options. Confirm that the ordering suffix matches the required physical footprint for your PCB layout. Check manufacturer documentation for any updates regarding component lifecycle status or recommended design-in guidelines before finalizing procurement plans.

Selection Notes

Select this component when a quad LVDS driver is needed to interface LVTTL logic with LVDS transmission lines. Ensure the system voltage aligns with the 3.0V to 3.6V operating range. Consider the TSSOP package if space constraints require a smaller footprint compared to standard SOIC packages. Verify that the required data rate does not exceed the specified maximum frequency limits.

Part Context

The FIN1031 belongs to the Fairchild Semiconductor LVDS driver family, later acquired by onsemi. It is specifically engineered for applications demanding high-speed data integrity with minimal power consumption. The device is often paired with companion receivers like the FIN1032 to form complete LVDS link solutions.

Replacement Considerations

The datasheet notes pin compatibility with equivalent RS-422 and LVPECL devices. Designers should verify electrical characteristics against specific alternative part numbers to ensure signal integrity and timing requirements are met during substitution.
