Dual-Mode HDMI 1.4b/MHL 2.0 Transmitter IP Core

IP core architecture supporting both HDMI and MHL connectivity standards in a single-chip solution

Silicon Image is a major supplier of mixed signal transmitter and receiver IP cores that incorporate the latest features of the HDMI® (High-Definition Multimedia Interface) and MHL® (Mobile High Definition Link) connectivity specifications. MHL technology delivers 1080p 60 uncompressed video with up to eight channels of digital audio while charging the mobile device, all through a 5-pin interface. MHL technology allows consumers to connect their mobile devices to a larger screen, such as a DTV or monitor, using existing connections on the mobile and CE products-enabling consumers to enhance their mobile experience by enjoying HD video entertainment, photos, applications, and games on the big screen.

The dual-mode HDMI and MHL transmitter IP core is the industry's first IP core that supports HD video/audio standards - MHL and HDMI. This IP core is intended for integration in SoC (system-on-chip) devices that require the efficient implementation of both HDMI and MHL in a single design that saves on engineering development and SoC photomask and manufacturing costs by sharing SoC die area between HDMI and MHL.

Operating in HDMI mode, Silicon Image's dual-mode transmitter core supports HDMI Version 1.4b including 3D video formats and all 4Kx2K formats. In MHL mode, this IP core supports 1080p 60Hz full HD resolution, native 3D formats and alpha-numeric key codes for advanced remote control capabilities as defined in the MHL 2.0 specification.

The dual-mode IP core supports all relevant audio formats up to 8-channel digital audio, while its color conversion allows convenient interfacing with most video devices. The core is configurable, providing SoC designers access to multiple internal interfaces and hardware blocks, potentially reducing integration time and gate count. The core includes digital logic, analog GDSII, models, software and documentation.

In addition to market-leading HDMI and MHL features, IP cores from Silicon Image offer numerous SoC integrator advantages, including reduced overall bill-of-materials (BOM) costs and lower power use for mobile applications. Silicon Image's industry leadership and unparalleled expertise helps its IP customers accelerate time-to-market through shorter design cycles and faster compliance testing.
