Overview
The DS90UB940TNKDRQ1 is a FPD-Link III to CSI-2 deserializer designed for automotive applications. It converts one or two FPD-Link III serial streams into MIPI CSI-2 format, supporting video resolutions up to WUXGA and 1080p60 with 24-bit color depth. The device operates with a pixel clock frequency of up to 170 MHz and supports data rates of 3.36 Gbps. It features two inputs and four outputs, housed in a 64-WQFN (9x9) package. Supply voltages are 1.71V to 1.89V and 3V to 3.6V. The component is AEC-Q100 qualified for Grade 2, functioning within a temperature range of -40°C to 105°C.
Feature Summary
- Converts FPD-Link III video and control data into MIPI CSI-2 format for system-on-chip integration
- Includes adaptive receiver equalization to compensate for channel insertion loss and skew
- Supports full-duplex bidirectional communication via I2C and SPI over the differential link
Applications
- Automotive information entertainment systems
- Vehicle instrument clusters and dashboard displays
- Rear seat entertainment systems
- Smart vehicle display interfaces
Procurement Notes
Verify the specific suffix DR against the required packaging configuration, as it indicates reel packaging distinct from cut tape variants. Confirm AEC-Q100 Grade 2 qualification aligns with the target automotive environment's thermal requirements. Ensure the 64-WQFN footprint matches the PCB layout specifications. Validate that the input signal source is compatible with FPD-Link III serializers such as the DS90UB947 or DS90UB929 series.
Selection Notes
Select this model when a dual-channel FPD-Link III input is required to drive a single CSI-2 output interface. Compare against the DS90UB948TNKDRQ1 if eight LVDS outputs are needed instead of MIPI CSI-2. Consider the DS90UH940TNKDRQ1 if HDCP encryption support is necessary for protected content. Ensure the design accommodates the 1.71V to 1.89V and 3V to 3.6V power domains specified for operation.
Part Context
This component belongs to the Texas Instruments DS90UB940 family of high-speed video deserializers. It is functionally related to the DS90UB940N-Q1 and DS90UB940TNKDTQ1, differing primarily in packaging and suffix designation. The part serves as a bridge between camera sensors using FPD-Link III and processing units utilizing MIPI CSI-2 interfaces.

FAQ
What is the maximum video resolution supported by this deserializer?
The device supports video resolutions up to WUXGA (1920x1200) and 1080p60 with 24-bit color depth.
Does the DS90UB940TNKDRQ1 support HDCP decryption?
No, the standard DS90UB940 does not include HDCP support. Models requiring HDCP functionality, such as the DS90UH940N-Q1, should be selected instead.
How does the device handle cable skew?
It provides automatic skew correction capabilities to compensate for mismatches in PCB routing, cable pair lengths, and connector imbalances without requiring special training patterns.
