2CDS90UB928Q-Q1

or DS90UB926Q-Q1 deserializer, compatible Serial Control Bus provides a complete digital interface for concurrent

• Low EMI FPD-Link Video Input transmission of high-speed video, audio, and control

• Supports High Definition (720p) Digital Video data for automotive display and image sensing

Format applications.

• 5-MHz to 85-MHz PCLK Supported The chipset is ideally suited for automotive video

• RGB888 + VS, HS, DE and I display systens with HD formats and automotive 2S Audio Supported

vision systems with megapixel resolutions. The • Up to 4 I

2S Digital Audio Inputs for Surround DS90UB927Q-Q1 incorporates an embedded Sound Applications bidirectional control channel and low latency GPIO

• 4 Bidirectional GPIO Channels with 2 Dedicated controls. This device translates a FPD-Link video

Pins interface into a single-pair high-speed serialized

• Single 3.3-V Supply with 1.8-V or 3.3-V interface. The FPD-Link III serial bus scheme

Compatible LVCMOS I/O Interface supports full duplex, high speed forward channel data

transmission and low-speed back channel

• AC-Coupled STP Interconnect Up to 10 Meters communication over a single differential link.

• DC-Balanced and Scrambled Data With Consolidation of audio, video, and control data over a

Embedded Clock single differential pair reduces the interconnect size

• Supports Repeater Application and weight, while also eliminating skew issues and

simplifying system design.
