NFC Everywhere

Wireless communication is becoming more and more commonplace in today’s society. Near Field Communication is one such way of us being able to communicate wirelessly. It allows you to interact securely with all objects around you with just a simple tap. At NXP, we relentlessly seek out new ways for applying technologies that strives to improve the experience of our users.

NFC is fast, seamless and easy to use and is also now available in millions of devices all over the world – devices that are now an integral part of our daily lives. With its focus on security, NFC transforms the already dynamic mobile user experience in a way that enables the “Internet of Things”. Now “smart posters”, location based check-in signs, a friend’s tablet, a ticketing or payment terminal can all interact with your mobile device, securely and seamlessly.

Check out this video on NFC technology being used in contactless credit/debit cards.

3.3 V, 2 differential channel, 2 : 1 multiplexer/demultiplexer switch for PCI Express Gen2

CBTL02042A/B is a 2 differential channel, 2-to-1 multiplexer/demultiplexer switch for PCI Express Generation 2 (Gen2), and other high-speed serial interface applications. This device is suitable for edge connector(s) with different signal sources on the motherboard for having input and output pins on the opposite of the package.

CBTL02042A/B has the capability to switch two differential signals to one of two locations. NXP has minimized the impedance of this switch such that the attenuation observed through the switch is negligible using a unique design technique.
