DS90C385MTDX

Overview

The DS90C385MTDX is a 3.3V programmable LVDS transmitter designed for flat panel display links, manufactured by Texas Instruments following its acquisition of National Semiconductor. It converts parallel RGB data into high-speed serial LVDS signals. The device supports up to 24-bit color depth and operates at clock frequencies up to 87.5 MHz with a maximum data rate of 2450 Mb/s. It accepts LVCMOS or LVTTL inputs and provides differential LVDS outputs. Powered by a single 3.3V supply within a 3V to 3.6V range, it functions in temperatures from -10°C to +70°C and is housed in a 56-pin TSSOP package.

Feature Summary

• Integrates a phase-locked loop (PLL) for clock generation without requiring external components
• Supports extended spectrum clocking to minimize electromagnetic interference emissions
• Features internal input jitter filtering to maintain signal integrity during transmission
• Provides selectable LVDS output swing levels to optimize power consumption and noise performance

Applications

• Flat panel display interfaces for laptops and monitors
• Video graphics adapter connections in personal computers
• Digital signage and advertising displays
• Automotive navigation and infotainment systems

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Confirm that the specific suffix matches the required temperature grade and packaging format. Ensure compatibility with the receiving LVDS decoder in the target display assembly before finalizing procurement orders.

Selection Notes

Select this component when a 24-bit parallel-to-LVDS conversion is required for display panels operating below 87.5 MHz. Compare against the DS90CR285 series if the application requires a receiver rather than a transmitter. Verify that the system design accommodates the 56-pin TSSOP footprint and the specific 3.3V power requirements.

Part Context

This part belongs to the DS90C385A family of LVDS transmitters originally developed by National Semiconductor. These devices are standard solutions for driving LCD panels via FPD-Link technology. The MTDX designation indicates a specific tape-and-reel packaging variant intended for automated surface-mount assembly processes.

Replacement Considerations

The DS90C385AMTX/NOPB is a verified equivalent from Texas Instruments. Other compatible transmitters include the SN75LVDS83 and THC63LVDM83A/D. Ensure pinout compatibility and electrical specifications match before substituting these alternatives.
