HDMI interface
In addition to a legacy analog audio video interfaces, for which NXP offers high-bandwidth switches and audio converters, today’s personal computers and notebooks include a HDMI output interface for digital HD content output.
The impedance matched (100 ohm differential) TMDS lines are critical for the design of a HDMI interface, with minimal line capacitance to allow maximized EYE openings of the differential signals and robust system level ESD protection. The EYE open pattern test is actively supported by NXP, which is a founding member of the HDMI consortium. Our Authorized Test Center in Caen, France, offers HDMI compliance measurements including TDR and our development teams can assist with the more challenging aspects of HDMI, including HDCP keys.
Our HDMI Interface conditioning solutions provide a clean, straight forward routing option with hardly any discrete components. These devices integrate functions such as level shifting to bridge the voltage levels demanded by the HDMI interface specification and sub-µ technology system chips of mobile devices no longer supporting high voltage levels.

ESD protections
To increase the reliability of computer interfaces and ensure a low return rate, NXP offers an extensive portfolio of solutions, integrated and discrete, for the protection of all interfaces.
ESD protections and level shifters for HDMI, DP, DVI
ESD protections for USB2 and USB 3, (e)SATA, Ethernet
ESD protections for analog AV interfaces

Low speed control functions and interfaces
Even when based on a highly integrated solution, personal computers (PCs) and notebooks will need additional IOs, temperature sensors and LED controllers. NXP offers a large portfolio of I2C controlled interfaces, GPIO expanders and sensors

Power management
As power efficiency becomes more important, manufacturer’s need efficient AC-DC controllers and high-performance microcontrollers to build power saving solutions, in active mode as well as in stand-by. NXP has a wide range of highly efficient AC-DC controllers and 8-bit and 32-bit micro-controllers.

RF remote control
The convergence of today’s multi media PCs to be used as media streaming devices increases the need for higher data rates and bidirectional communication between remote controller and the computer. The regular infra-red remote control is progressively being replaced with very low power RF, such as 802.15.4/ RF4CE solutions.

To complete system-on-chip solutions, NXP offers a large portfolio of single functions in a small package, with different packaging options to prevent probing for enhanced security.

NXP Semiconductors has a comprehensive port-folio of discrete components, including transistors, diodes and ESD protections.
