Video Scaler 4K

General Description

Studio-quality RGB video scaler optimized for UHD / 4K digital scaling solutions. Support for 2 x pixels/clock with 600 MHz effective pixel clock rate or better. Simple input/output interfaces compatible with AXI4-stream. No frame buffer or external memory required.

Key Design Features

- Optimized for 4K / UHD video
- But will support any video resolution up to 2¹⁶ x 2¹⁶ pixels
- Independent vertical and horizontal scaling (upscale or downscale)
- Fully programmable scaling parameters
- Pipelined architecture with simple flow control
- ABMA / AXI4-stream compatible interfaces
- Features a 5x5-tap polyphase filter core with 16-phases
- Optional decimation and interpolation input and output filters
- Supports 2 x 24-bit RGB 8:8:8 pixels per clock
- Generates one scaled output frame for every input frame
- No external frame buffer or external memory requirement
- Supports 300 MHz+ operation on mid-range FPGA devices
  (i.e. equivalent to 600 MHz+ @ 2 x pixels / clock)

Applications

- Studio quality video scaling optimized for 4K / UHD
- Broadcast video equipment
- Picture-in-picture (PiP), Picture-by-picture (PbP), digital zoom
- Video scaling for flat panel displays, image sensors and cameras,
  portable devices, video games/consoles, video format converters,
  set-top boxes, smart TVs etc.
