DS90CR218MTDX

Specialized Overview

The DS90CR218MTDX is an LVDS interface integrated circuit manufactured by Texas Instruments. It functions as a receiver with 3 LVDS inputs and 21 CMOS/TTL outputs. The device supports data rates up to 1785 Mb/s, corresponding to a maximum input clock of 85 MHz. It operates on a single 3.3 V power supply, with a voltage range of 3.0 V to 3.6 V. The component is housed in a 48-pin TSSOP package and is rated for an operating temperature range of -10°C to +70°C.

Specialized Feature Summary

• Performs deserialization of three differential LVDS data streams into parallel CMOS or TTL output formats.
• Integrates a phase-locked loop (PLL) to generate internal clocks without requiring external components.
• Maintains compatibility with the TIA/EIA-644 LVDS standard for reliable signal transmission.

Specialized Applications

• High-speed video display interfaces
• Data acquisition systems
• Industrial control networks

Specialized Procurement Notes

Verify the specific suffix 'MTDX' against official datasheets to confirm tape-and-reel packaging and exact electrical grade. Ensure the design accommodates the specified -10°C to +70°C industrial temperature range. Confirm that the 48-pin TSSOP footprint matches the target PCB layout requirements before finalizing procurement.

Specialized Selection Notes

Select this component when deserializing three LVDS channels into a wide 21-bit parallel bus is required. It is suitable for applications needing high throughput up to 1.785 Gbps. Consider the thermal performance within the TSSOP-48 package if operating near the upper temperature limit. Verify that the system logic levels match the CMOS/TTL output specifications.

Specialized Part Context

This part belongs to the DS90CR218A family of LVDS receivers. It is designed to replace older parallel interfaces with serial LVDS links. The device simplifies board layout by reducing trace count while maintaining high data integrity over longer distances compared to parallel CMOS buses.
