DS90C189TWRTDTQ1

Overview

The DS90C189TWRTDTQ1 is a low-power serializer designed for automotive applications, certified under AEC-Q100 standards. It operates on a single 1.8V supply with a voltage range of 1.71V to 1.89V and consumes approximately 50mA of current. The device accepts 24 LVCMOS inputs and converts them into two LVDS output channels, supporting a data rate of 5.18 Gb/s. It supports QXGA resolution at 60Hz in single-pixel mode or WUXGA+ resolution in dual-pixel output mode. Housed in a VQFN-64 package, it functions within an extended temperature range from -40°C to +115°C.

Feature Summary

• Converts high-color-depth parallel LVCMOS data into differential LVDS serial streams for long-distance transmission
• Supports flexible pixel output modes including single-pixel input/output and single-pixel input/dual-pixel output configurations
• Engineered for automotive environments with qualified reliability and wide operating temperature tolerance

Applications

• Connecting host processors to flat panel displays in automotive infotainment systems
• Video bridge interfaces requiring high-resolution support up to QXGA
• Low-power display driver architectures in vehicle cockpit electronics

Procurement Notes

Verify the specific suffix 'DT' against official Texas Instruments documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with the DS90C189-Q1EVM development kit for validation. Confirm that the component meets the required AEC-Q100 qualification levels for your specific automotive application tier before finalizing orders.

Selection Notes

Select this serializer when interfacing LVCMOS sources with LVDS-compatible displays in automotive settings. It is suitable for designs requiring QXGA resolution at 60Hz. Consider the VQFN-64 package constraints and thermal dissipation requirements given the 150mW power dissipation. Verify that the system architecture supports the 4D+C LVDS interface format generated by the device.

Part Context

This component belongs to the DS90C189 series of FPD-Link serializers. It serves as a bridge between digital video sources and display panels. The device is part of Texas Instruments' portfolio for automotive connectivity solutions, focusing on reducing pin counts and signal interference through serialisation technology.

Replacement Considerations

Check for other variants within the DS90C189 family that may offer different packaging or speed grades. Ensure any substitute maintains the same LVCMOS-to-LVDS conversion capability and AEC-Q100 certification level.
