DS90CR283MTD/NOPB

Specialized Overview

The DS90CR283MTD/NOPB is a transmitter component within the Channel Link chipset family, designed to serialize parallel data for high-speed transmission. It converts 28 bits of CMOS/TTL input data into four LVDS differential data streams and one clock stream. Operating with a maximum clock frequency of 66 MHz, it achieves a total data throughput of 1.848 Gbit/s (462 Mbps per channel). The device utilizes a built-in phase-locked loop (PLL) requiring no external components. It operates on a single 5V supply voltage, with a recommended range of 4.75V to 5.25V. The unit is housed in a low-profile 56-lead TSSOP package.

Specialized Feature Summary

• Serializes 28-bit parallel CMOS/TTL data into four LVDS channels plus a dedicated clock channel
• Integrates an internal phase-locked loop (PLL) eliminating the need for external timing components
• Supports rising edge data strobe synchronization between transmitter and receiver
• Provides power-down mode functionality to minimize current consumption during idle states

Specialized Applications

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

Specialized Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature rating. Confirm compliance with RoHS directives if environmental regulations apply to the assembly process. Ensure the design supports the 5V logic level requirements specified in the datasheet. Review the life support policy restrictions before integrating this component into safety-critical systems.

Specialized Selection Notes

Select this component when a system requires converting wide parallel buses into a serialized LVDS link to reduce cabling complexity. It is suitable for applications needing up to 1.848 Gbit/s throughput over short to medium distances. Designers must account for the 5V operating voltage and ensure proper decoupling for the PLL section. Verify that the receiving end utilizes a compatible Channel Link receiver, such as the DS90CR284.

Specialized Part Context

This component belongs to the National Semiconductor Channel Link family, now managed by Texas Instruments following their acquisition. The DS90CR283 functions specifically as the transmitter side of the pair, working in conjunction with the DS90CR284 receiver. This architecture was developed to replace traditional parallel interfaces like SCSI or VMEbus in space-constrained environments.

Specialized Replacement Considerations

Publicly confirmed direct substitutes include the DS90CR284MTD/NOPB for the complementary receiver function. For equivalent performance in similar packages, consider the DS90CR285MTD/NOPB or DS90CR286AMTD/NOPB series, which offer comparable serialization capabilities.
