Recommended alternative parts

  • DS90UB927Q-Q1  - The device has the SAME FUNCTIONALITY and PINOUT as the compared device but is NOT an exact equivalent.   Offers same functionality except HDCP
  • DS90UH925Q-Q1  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Same functionality with Parallel LVCMOS RGB interface
  • DS90UR907Q-Q1  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Previous-generation serializer with FPD-Link receive interface. Recommend if bidirectional control channel is not required.
  • DS90UR905Q-Q1  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   Previous-generation serializer with Parallel LVCMOS RGB interface. Recommend if bidirectional control channel is not required.

Description

The DS90UH927Q-Q1 serializer, in conjunction with a DS90UH928Q-Q1 or DS90UH926Q-Q1 deserializer, provides a solution for secure distribution of content-protected digital video within automotive entertainment systems. This chipset translates a FPD-Link video interface into a single-pair high-speed serialized interface. The digital video data is protected using the industry standard High-Bandwidth Digital Content Protection (HDCP) copy protection scheme. The FPD-Link III serial bus scheme supports full duplex, high speed forward channel data transmission and low-speed back channel communication over a single differential link. Consolidation of audio, video, and control data over a single differential pair reduces the interconnect size and weight, while also eliminating skew issues and simplifying system design.

The DS90UH927Q-Q1 serializer embeds the clock, content protects the data payload, and level shifts the signals to high-speed differential signaling. Up to 24 RGB data bits are serialized along with three video control signals, and up to four I2S data inputs.

The FPD-Link data interface allows for easy interfacing with data sources while also minimizing EMI and bus width. EMI on the high-speed FPD-Link III bus is minimized using low voltage differential signaling, data scrambling and randomization, and dc-balancing.

The HDCP cipher engine is implemented in both the serializer and deserializer. HDCP keys are stored in on-chip memory.
