DS90UB914ATRHSRQ1

Overview

The DS90UB914ATRHSRQ1 is a FPD-Link III deserializer designed for automotive imaging applications. It supports input pixel clocks from 25 MHz to 100 MHz and handles 10-bit data up to 100 MHz or 12-bit data up to 75 MHz. The device features one high-speed serial input and twelve LVCMOS outputs, operating on a single 1.8 V supply voltage within the range of 1.71 V to 3.6 V. It utilizes a 48-WQFN (7x7) package with exposed pad and functions across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Supports 2:1 multiplexer for selecting between two input image sensors
• Provides bidirectional control channel with I2C interface for low-latency communication
• Includes adaptive equalization to compensate for cable loss in long-distance transmission

Applications

• Automotive surround view systems (SVS)
• Front and rear camera modules
• Driver monitoring systems (DMS)

Procurement Notes

Verify the specific suffix JQ1 versus RQ1 when sourcing, as these denote different qualification grades or packaging variants. Confirm AEC-Q100 Grade 2 compliance requirements match the target application environment. Ensure ESD protection ratings meet ISO 10605 standards for the intended installation location.

Selection Notes

Select this component when interfacing with sensors requiring up to 12-bit depth at lower frame rates or 10-bit at higher frequencies. Consider the 48-pin WQFN footprint for space-constrained PCB layouts. Evaluate cable length requirements against the internal equalizer capabilities before finalizing the design architecture.

Part Context

This part belongs to the DS90UB914A-Q1 family of FPD-Link III deserializers. It complements serializers like the DS90UA101 to form complete video link solutions. The device integrates DC-balanced encoding and scrambling to support AC-coupled interconnects commonly used in automotive harnesses.

Replacement Considerations

DS90UB914ATRHSJQ1 serves as a direct functional substitute within the same package and pinout configuration.
