DS90C383AMTDX

Overview

The DS90C383AMTDX is a 3.3V programmable LVDS transmitter designed for 24-bit Flat Panel Display (FPD) Link applications operating at 65 MHz. It converts parallel CMOS or TTL inputs into low-voltage differential signals for high-speed transmission. The device features four drivers and supports data rates up to 1.8 Gb/s. It operates within a supply voltage range of 3 V to 3.6 V and functions across an industrial temperature range of -40°C to +85°C. The component is housed in a 56-pin TSSOP package.

Feature Summary

• Programmable output characteristics allow customization for specific display interface requirements.
• Supports FPD-Link protocol for connecting flat panel displays to system controllers.
• Converts single-ended digital inputs to differential LVDS outputs for noise immunity.

Applications

• Flat panel display interfaces
• LVDS transmitter circuits
• Digital video signal transmission

Procurement Notes

Verify the exact suffix configuration against the manufacturer's current documentation, as designations may indicate specific packaging or qualification levels. Confirm availability status, as older National Semiconductor parts often carry end-of-life notices. Ensure the source provides valid RoHS compliance data matching the NOPB designation if present.

Selection Notes

Select this component when a 24-bit LVDS transmitter is required for FPD-Link architectures. Verify that the input logic levels match the available CMOS or TTL options. Check thermal performance requirements against the specified -40°C to +85°C operating range. Ensure the 56-pin TSSOP footprint fits the target PCB layout constraints.

Part Context

This part belongs to the DS90C383 series from Texas Instruments, following the acquisition of National Semiconductor. It serves as the transmitter counterpart to receivers like the DS90CF384. The series is engineered specifically for driving flat panel displays over long cables using differential signaling standards.

Replacement Considerations

The DS90C383MTD/NOPB is a documented equivalent within the same family. Verify pin compatibility and electrical specifications before substitution. Other variants in the DS90C383 series may offer different temperature ranges or packaging options.
