FIN1048MTC

Overview

The FIN1048MTC 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 3.3V power supply within a range of 3.0V to 3.6V and supports data rates greater than 400Mbps. Key electrical parameters include a maximum propagation delay of 2.5ns, a maximum differential pulse skew of 0.4ns, and a maximum operating frequency of 375MHz under specified load conditions. It features fail-safe protection for open-circuit, shorted, and terminated conditions.

Feature Summary

• Flow-through pinout architecture simplifies printed circuit board layout processes.
• Integrated fail-safe protection ensures stable outputs during open-circuit or shorted input conditions.
• Power-off protection maintains high-impedance states when the supply voltage is removed.
• Pin-compatible design allows direct replacement for equivalent RS-422 and LVPECL devices.

Applications

• High-speed transfer of clock signals in digital systems
• Data communication links requiring low electromagnetic interference
• Point-to-point interconnects between logic components

Procurement Notes

Verify the package type matches the specific suffix code. The 'M' suffix indicates a 16-Lead Small Outline Integrated Circuit (SOIC), while 'MTC' denotes a 16-Lead Thin Shrink Small Outline Package (TSSOP). Confirm that the required quantity aligns with standard tape and reel availability if applicable. Ensure the operating temperature range meets system requirements.

Selection Notes

Select this component when a four-channel LVDS to LVTTL translation is required for high-speed data paths. Consider the flow-through pinout for simplified routing compared to non-flow-through alternatives. Verify that the 3.3V supply voltage aligns with the system's power distribution network. Evaluate the 2.5ns propagation delay against the timing constraints of the destination logic family.

Part Context

This receiver belongs to the FIN104x series of LVDS components manufactured by Fairchild Semiconductor, now part of onsemi. It is functionally paired with the FIN1047 driver to form complete transmission lines. The series provides solutions for reducing electromagnetic interference in high-frequency applications while maintaining low power consumption across various industrial and consumer electronics platforms.

Replacement Considerations

The datasheet notes pin compatibility with equivalent RS-422 and LVPECL devices. Engineers should verify voltage level translations and drive strengths when substituting these legacy standards. Direct replacements must match the 16-lead SOIC or TSSOP footprint and maintain similar propagation delay characteristics.
