FIN1032MX

Overview

The FIN1032MX is a quad receiver designed for high-speed interconnect utilizing Low Voltage Differential Signaling (LVDS) technology. It translates LVDS levels to LVTTL signal levels with a typical differential input threshold of 100mV. The device operates on a 3.0V to 3.6V power supply and supports data rates greater than 400Mbs. Key electrical parameters include a maximum propagation delay of 2.5ns, a maximum differential pulse skew of 0.4ns, and a typical operating current of 15mA. It features fail-safe protection for open-circuit, shorted, and terminated conditions, ensuring reliable operation in various signal environments.

Feature Summary

• Translates LVDS signals to LVTTL levels for high-speed data transfer
• Includes fail-safe protection against open-circuit, shorted, and terminated inputs
• Provides power-off protection to prevent excessive current draw during system power cycles

Applications

• High-speed clock distribution networks
• Data bus interconnects requiring low EMI
• Point-to-point or multi-drop serial communication links

Procurement Notes

Verify the specific package variant when ordering, as the MX suffix denotes the 16-lead SOIC package. Confirm that the application environment remains within the specified -40°C to +85°C temperature range. Ensure that the 3.3V supply voltage stays between 3.0V and 3.6V for optimal performance. Check for updated part numbers on the manufacturer's website due to historical Fairchild Semiconductor integration changes.

Selection Notes

Select this component when interfacing LVDS sources with LVTTL logic domains. It serves as a direct replacement for equivalent RS-422 and LVPECL devices where pin compatibility is required. Consider pairing it with the companion FIN1031 driver for complete LVDS link solutions. Evaluate the 16-lead SOIC package constraints against available PCB space requirements.

Part Context

This device belongs to the FIN10 series of LVDS receivers manufactured by ON Semiconductor. It was originally developed under the Fairchild Semiconductor brand before corporate integration. The FIN1032 complements the FIN1031 driver, forming a standardized solution for high-speed differential signaling applications compliant with TIA/EIA-644 standards.

Replacement Considerations

Publicly confirmed substitutes include the FIN1032MTCX (TSSOP package) and legacy equivalents such as the DS90LV002A. Verify pinout compatibility and electrical specifications before swapping packages or manufacturers.
