MAX96752

• Converts the oLDI/LVDS signals from GMSL Deserializers to standard HDMI 2.0
• Useful for debug and testing of GMSL display systems
• Designed to fit all GMSL oLDI Deserializers Evaluation Boards using the equipped Samtec board-to-board connectors
• Maximum pixel clock of 300 MHz enabling up to 4k resolutions at 30 fps
• Includes inputs for GMSL I²S signals

The AD-GMSL-D-E-ADP# GMSL oLDI/LVDS to HDMI adapter converts the oLDI/LVDS signals from GMSL Deserializers to standard HDMI 2.0. This adapter is to be used for debug and system testing only and is not designed to be fully implemented in a final system architecture. This solution has a maximum pixel clock of 300 MHz which is approximately a 3840x2160 at 30 Hz (4k30). This maximum value can only be achieved with a dual-link GMSL2 SerDes pair as it requires a bandwidth greater than what a single GMSL2 link provides.

The adapter is designed to fit all GMSL oLDI Deserializers Evaluation Boards using the equipped Samtec board to board connectors. It utilizes automatic configuration by “seeing” the incoming oLDI/LVDS signals and adjusting the HDMI’s output based upon the received signals. A UART output is available to be used for monitoring the automatic configuration process.

This adapter includes inputs for I²S audio and was designed in such a way that the GMSL I2S signals (from the forward channel) could be used as inputs. Like the video setup, the adapter automatically detects and adds the I2S audio data into the HDMI signals without the need to program the adapter itself. The parts that this adapter works with includes any subvariant of 'B', 'F', and 'R' of the MAX96752.

The MAX96752 evaluation kit (EV kit) provides a proven design to evaluate the MAX96752 high-bandwidth Gigabit Multimedia Serial Link (GMSL) deserializer with spread spectrum and full-duplex control channel with the use of a standard FAKRA coaxial cable or HSD STQ cable. The EV kit also includes Windows^® 10 application software to provide a simple graphical user interface (GUI) for exercising features of the device.

For complete GMSL evaluation, order the MAX96752 coax EV kit with a companion GMSL-2 serializer board (MAX96751 coax EV kit, see note in Ordering Information).

Note: In the following sections, deserializer means MAX96752 and serializer means MAX96751.

Note: This document applies to both coax and HSD-STQ evaluation kits, coax EV kit is referenced in this document.
