STEVAL-CCH003V2 STMicroelectronics

S T E VA L - C C H 0 0 3 V 2 HDMI interface evaluation kit based on the HDMI2C1-14HD (main board plus daughter board) Data brief Description The STEVAL-CCH003V2 evaluation kit demonstrates how the HDMI2Cx-14HD series can be a simple and fast means to reach full compliance with stringent HDMI 1.4 standards. This evaluation kit is made up of a main board which can accept an optional daughter board through dedicated connectors. It provides easy access to all HDMI control stage signals and the main board power supplies (+5 V of the DDC bus, +3.3 V of the CEC bus, and VDD of the ASIC HDMI). The main board can be used in a standalone Features configuration as a plug and play board to show Interface between any HDMI source the interface is working properly. It can also be equipment (transmitter) and an HDMI sink used to demonstrate the capability of the (receiver) through an HDMI cable HDMI2C1-14HD device to drive cables with a HDMI 2.0 (4K / 2K 60 fps) compliant from high capacitance load (poor quality or long HDMI -40 to 85 C cable). Fully integrated ESD protection Finally, it can be used to evaluate power RoHS compliant consumption in various operating configurations (e.g., transmitter in standby mode, various ASIC power supply voltage values and ruggedness against external stresses).
