FIN1218MTDX

Overview

The FIN1218MTDX is a high-speed LVDS serializer and deserializer integrated circuit manufactured by Fairchild Semiconductor. It supports data rates up to 1.785 Gbps, featuring three inputs and twenty-one outputs. The device operates within a voltage range of 3.0 V to 3.6 V and utilizes a 48-pin TSSOP package with a width of 6.10 mm. It converts low-voltage differential signals to LVTTL output levels, ensuring reliable signal integrity for serial data transmission applications requiring precise timing and synchronization.

Feature Summary

• Supports high-speed serial data transmission at 1.785 Gbps
• Converts LVDS input signals to LVTTL output levels
• Features a compact 48-pin TSSOP surface-mount package

Applications

• High-definition video signal distribution systems
• Digital signage and display driver circuits
• Industrial communication interfaces requiring LVDS-to-LVTTL conversion

Procurement Notes

Verify the component status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm that the 48-TFSOP package dimensions match the target PCB footprint. Ensure that the LVTTL output voltage levels are compatible with the receiving logic family in the design. Check for any available replacement components from onsemi if the original Fairchild part is unavailable.

Selection Notes

Select this component when a deserializer function is required to convert three LVDS input channels into twenty-one parallel LVTTL outputs. The 1.785 Gbps data rate suitability should be validated against the system's bandwidth requirements. Consider the thermal performance within the 48-pin TSSOP package for the specific application environment. Verify that the power supply voltage range aligns with the system's 3.3 V logic standards.

Part Context

The FIN1218MTDX belongs to the series of LVDS serializers and deserializers produced by Fairchild Semiconductor. These devices are designed to facilitate long-distance, noise-immune data transmission using differential signaling. The MTDX suffix indicates the specific pinout and packaging configuration. This component represents a solution for bridging differential bus technologies with standard TTL logic families in electronic systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component status is listed as obsolete, engineers must consult current onsemi product catalogs for functional equivalents. Verify pin compatibility and electrical specifications when evaluating alternative deserializer ICs.
