DS90C385MTD

Overview

The DS90C385MTD is a 3.3V programmable LVDS transmitter designed for flat panel display links, manufactured by National Semiconductor (now Texas Instruments). It converts parallel LVTTL/LVCMOS data into four channels of low-voltage differential signaling (LVDS) for high-speed transmission. The device supports a maximum data rate of 2450 Mb/s and operates with an input clock frequency up to 87.5 MHz. It accepts 24-bit RGB data along with timing and control signals. The component functions within a supply voltage range of 3.0 V to 3.6 V and is housed in a TSSOP-56 package suitable for surface-mount installation.

Feature Summary

• Integrates a phase-locked loop (PLL) for clock recovery and jitter filtering without requiring external components
• Supports flexible input compatibility with standard LVTTL and LVCMOS logic levels
• Enables reduced electromagnetic interference through configurable LVDS output swing settings

Applications

• Flat panel display interfaces for LCD panels
• Video graphics adapter (VGA) and SVGA signal transmission
• XGA and SXGA display link implementations

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Confirm that the specific suffix matches the required package type and temperature rating. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a parallel-to-LVDS conversion is required for display applications. It is suitable for designs needing up to 24 bits of data throughput at frequencies up to 87.5 MHz. Consider the TSSOP-56 footprint constraints during PCB layout. Verify that the system power supply remains within the 3.0 V to 3.6 V operating range for reliable performance.

Part Context

This part belongs to the DS90C385A series of LVDS interface integrated circuits. It serves as the transmitter counterpart to receivers such as the DS90C386 or DS90CR286. The device is part of the FPD-Link family, designed to replace traditional parallel LVDS solutions with fewer traces and lower power consumption. It is commonly used in portable electronics and industrial display systems.

Replacement Considerations

The DS90C385AMT/NOPB is a direct equivalent from Texas Instruments following the acquisition. Other compatible transmitters include the SN75LVDS83 and THC63LVDM83C. Ensure pinout compatibility and electrical specifications match before substituting.
