DS90CR284MTDX/NOPB

Specialized Overview

The DS90CR284MTDX/NOPB is a receiver integrated circuit within the Channel Link family, designed to convert serialized LVDS data streams back into parallel CMOS/TTL formats. It supports a maximum clock frequency of 66 MHz, enabling a total data throughput of 1.848 Gbit/s across four differential data channels. The device accepts a differential clock input and provides a recovered TTL clock output. Operating on a single 5V supply with a range of 4.75V to 5.25V, it features a low power consumption design with a dedicated power-down mode reducing dissipation below 0.5 mW. The component is housed in a 56-lead TSSOP package.

Specialized Feature Summary

• Converts serialized LVDS signals into 28-bit parallel CMOS/TTL outputs
• Includes an internal phase-locked loop for clock recovery without external components
• Provides a dedicated power-down mode for significant energy reduction
• Supports rising edge data strobe synchronization

Specialized Applications

• High-speed point-to-point data transmission links
• Parallel bus replacement applications requiring cable reduction
• Industrial control systems utilizing LVDS interconnects

Specialized Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature rating. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supply voltage aligns with the recommended 5V operating conditions specified in the datasheet.

Specialized Selection Notes

Select this component when replacing legacy parallel buses with a serialized link to reduce cabling complexity. Ensure the system design accommodates the 56-pin TSSOP footprint and provides adequate decoupling for the PLL and logic supplies. Verify that the receiving board layout maintains differential impedance matching for optimal signal integrity.

Specialized Part Context

This receiver functions as the counterpart to the DS90CR283 transmitter in the Channel Link chipset. Together, they facilitate the serialization of 28-bit data streams over a minimal number of conductors. The device is part of a broader interface solution aimed at minimizing connector size and shielding requirements in high-speed digital systems.

Specialized Replacement Considerations

The DS90CR284SLC is listed as a discontinued alternative. Designers should verify pin compatibility and electrical characteristics before substituting older package variants.
