DS90CR288MTDX

Specialized Overview

The DS90CR288MTDX is a +3.3V Rising Edge Data Strobe LVDS 28-Bit Channel Link Receiver designed for high-speed data transmission up to 75 MHz. It converts four LVDS data streams back into 28 bits of CMOS/TTL data, achieving a throughput of 2.10 Gbit/s (262.5 Mbytes/sec). The device operates within a supply voltage range of 3.0 V to 3.6 V and supports an operating temperature from -10°C to +70°C. Key electrical parameters include a differential input threshold of ±100 mV, a typical power dissipation of 1.61 W at +25°C, and a receiver supply current of up to 130 mA at 75 MHz. It features a low profile 56-lead TSSOP package.

Specialized Feature Summary

• Supports 20 to 75 MHz shift clock frequencies with a 50% duty cycle on the receiver output clock.
• Features best-in-class setup and hold times on both transmitter inputs and receiver outputs.
• Includes a dedicated Tx + Rx Powerdown mode that reduces maximum power consumption to less than 400µW.
• Utilizes a PLL requiring no external components and provides a ±1V common-mode range around +1.2V.

Specialized Applications

• High-speed point-to-point data transmission applications requiring wide bus reduction.
• Systems needing EMI and cable size mitigation for high-speed TTL interfaces.
• Upgrading existing 5V Channel Link systems to 3.3V architectures using backward compatible designs.

Specialized Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm the specific ordering suffix matches the required package type and environmental compliance standards. Ensure the supplier provides valid traceability documentation. Cross-reference the part number with the latest Texas Instruments or National Semiconductor product announcements to confirm availability status.

Specialized Selection Notes

Select this receiver when paired with the DS90CR287 transmitter for a complete 28-bit channel link solution. Ensure the system design accommodates the 3.3V logic levels, as inputs are not 5V tolerant. Verify that the interconnect media maintains skew below 130ps at 75MHz to preserve the data sampling window. Consider the 56-lead TSSOP footprint during PCB layout planning.

Specialized Part Context

This component belongs to the National Semiconductor Channel Link family, now managed by Texas Instruments. It serves as the receiver counterpart to the DS90CR287 transmitter. The chipset addresses challenges associated with wide, high-speed parallel interfaces by serializing data over LVDS links. It is specifically engineered for applications demanding reduced cable count and lower electromagnetic interference.

Specialized Replacement Considerations

The DS90CR288AMTDX is a documented alternative offering extended temperature support up to 85°C. Designers upgrading from older 5V versions should verify compatibility with the DS90CR283/284 pairs. Check for updated datasheet revisions to ensure alignment with current electrical specifications and pinout configurations.
