DS90CR285MTD

Specialized Overview

The DS90CR285MTD is a 3.3V Rising Edge Data Strobe LVDS interface integrated circuit designed for high-speed data transmission. It features four drivers and twenty-eight receivers, supporting a maximum data rate of 1848 Mb/s per channel. The device accepts LVCMOS or LVTTL inputs and converts them to differential LVDS outputs. It operates within a supply voltage range of 3 V to 3.6 V and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a 56-pin TSSOP, it facilitates efficient parallel-to-serial conversion for display and camera link applications.

Specialized Feature Summary

• Supports 28-bit parallel data channels with rising edge data strobe synchronization
• Converts single-ended LVCMOS/LVTTL signals to low-voltage differential signaling (LVDS)
• Enables high-speed data transfer up to 1848 Mb/s per channel
• Integrated power management for 3.3V operation with low power dissipation

Specialized Applications

• Camera Link digital image acquisition systems
• High-resolution flat panel display interfaces
• Industrial machine vision data links
• Medical imaging equipment signal transmission

Specialized Procurement Notes

Verify the complete part number including suffixes such as NOPB or BX to ensure correct packaging and RoHS compliance status. Confirm the package type matches the required PCB footprint, typically TSSOP-56 for this series. Check manufacturer documentation for moisture sensitivity level handling requirements during assembly. Ensure the specific revision matches the design specifications for timing parameters.

Specialized Selection Notes

Select this component when a 28-channel LVDS transmitter is required for parallel data expansion. Compare against the DS90CR286 if receiver functionality is needed instead. Consider the DS90CR287 for applications requiring higher clock speeds up to 85 MHz. Verify input voltage compatibility with the source logic family, ensuring support for both LVCMOS and LVTTL standards.

Specialized Part Context

This device belongs to the DS90CR285/286 family of Rising Edge Data Strobe LVDS transmitters and receivers. It was originally developed by National Semiconductor before Texas Instruments acquired the product line. The MTD variant specifically denotes the surface-mount TSSOP package option. It serves as a key interface solution for bridging standard logic levels to differential LVDS buses in professional video and display equipment.

Specialized Replacement Considerations

The DS90CR285SLC is a documented obsolete alternative in the same family, utilizing a 64-NFBGA package. Direct pin-compatible replacements are not explicitly listed in public datasheets; however, the DS90CR285MTD/NOPB is the current active manufacturing version replacing earlier non-compliant variants.
