DS90UB925Q-Q1 (ACTIVE)

5 - 85 MHz 24-bit Color FPD-Link III Serializer with Bidirectional Control Channel

 

Description

The DS90UB925Q-Q1 serializer, in conjunction with the DS90UB926Q-Q1 deserializer, provides a complete digital interface for concurrent transmission of high-speed video, audio, and control data for automotive display and image sensing applications.

The chipset is ideally suited for automotive video-display systems with HD formats and automotive vision systems with megapixel resolutions. The DS90UB925Q-Q1 incorporates an embedded bidirectional control channel and low latency GPIO controls. This chipset translates a parallel interface into a single pair high-speed serialized interface. The serial bus scheme, FPD-Link III, supports full duplex of high-speed video data transmission and bidirectional control communication over a single differential link. Consolidation of video data and control over a single differential pair reduces the interconnect size and weight, while also eliminating skew issues and simplifying system design.

The DS90UB925Q-Q1 serializer embeds the clock, DC scrambles & balances the data payload, and level shifts the signals to high-speed low voltage differential signaling. Up to 24 data bits are serialized along the video control signals.

Serial transmission is optimized by a user selectable de-emphasis. EMI is minimized by the use of low voltage differential signaling, data scrambling and randomization and spread spectrum clocking compatibility.
