Lattice Announces Video Display Interfaces Suite For HDMI, DVI, and 7:1 LVDS

Lattice is targeting all display market segments with comprehensive solutions for three popular multimedia standards. The HDMI solution is useful for processing high-definition, non- copy protected audio-visual signals from network servers, industrial cameras, and other sources to projectors and other video displays. The DVI solution is particularly useful for digital signage, consumer and industrial customers who require only video and no audio for their application and are sensitive to any additional royalty costs. The 7:1 LVDS solution is excellent for transferring large amounts of video data from board to board within an electronic system (embedded applications).

The silicon-proven Reference Designs implement the Physical Layer Functions for three popular video standards for reliable and efficient serial transmission. The first Reference Design, HDMI Physical Interface, leverages the LatticeECP3 SERDES and its associated PLL to automatically detect the HDMI resolution. This allows a design to use fewer components and enables quicker time to market because no processor firmware needs to be written. Further cost saving is achieved as the discrete PHY is removed and integrated into the LatticeECP3 device.

The second Reference Design, DVI Physical Interface, encodes/decodes and serializes/de-serializes video data on the low power embedded SERDES in LatticeECP3 FPGAs using the Transition Minimized Differential Signaling mechanism. It can both transmit and receive DVI video data.

The third Reference Design, 7:1 LVDS Physical Interface, is implemented on the 1Gbps LVDS-capable source synchronous differential I/Os. This Reference Design leverages unique pre-engineered I/O components in newer Lattice FPGA families, such as high-speed LVDS buffers, DDR registers, precision PLLs and built-in gearbox logic, to optimally manage the data rates. The embedded applications also frequently require image and video processing before or after the transmission. Lattice's low-cost, mid-range FPGAs enable designers to build integrated devices with both processing and efficient data transmission functionalities.

“We are pleased to offer our customers a comprehensive suite of video display interfaces for developing advanced and high performance video display applications,” said Shakeel Peera, Director of Marketing for High Density Solutions at Lattice Semiconductor. “Lattice is committed to providing a comprehensive silicon ecosystem that includes evaluation kits, reference designs, software tools and IP cores so our customers can accelerate their time to market.”
