DS90C365MTDX

Overview

The DS90C365MTDX is a programmable LVDS transmitter manufactured by National Semiconductor, now part of Texas Instruments. It functions as an 18-bit flat panel display link transmitter operating at data rates up to 87.5 MHz. The device utilizes a single +3.3V power supply and features a 48-pin TSSOP package with a 0.5mm pitch. It supports CMOS or TTL input logic levels and operates within a commercial temperature range of -10°C to +70°C. The component integrates three differential line drivers compliant with EIA/TIA-644 standards for high-speed serial data transmission.

Feature Summary

• Programmable architecture designed specifically for flat panel display applications
• Converts parallel digital video signals into low-voltage differential signaling
• Supports standard CMOS and TTL input voltage thresholds

Applications

• Flat Panel Display (FPD) Link systems
• High-resolution LCD panel interfaces
• Video signal transmission in display controllers

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix 'X' indicates reel packaging if required by assembly processes. Ensure the device meets RoHS compliance standards corresponding to the NOPB variant if lead-free composition is mandatory for the target application environment.

Selection Notes

Select this component when an 18-bit LVDS transmitter is required for FPD-Link compatibility. Compare against the DS90C363 series if quad driver configurations are needed instead of triple. Verify that the 87.5 MHz maximum data rate aligns with the display resolution requirements. Ensure the 48-pin TSSOP footprint matches the PCB layout constraints.

Part Context

This device belongs to the DS90C36x family of LVDS interface ICs developed by National Semiconductor. These components were widely used in early generation flat panel display solutions before transitioning to higher bandwidth technologies. The product line was transferred to Texas Instruments following the acquisition of National Semiconductor's semiconductor business.

Replacement Considerations

The DS90C365AMT/NOPB serves as a direct equivalent with identical electrical specifications. The DS90C365MTX represents the same core functionality with potential packaging variations. Cross-reference pinouts and timing parameters strictly between these variants to ensure compatibility.
