2-lane DisplayPort to VGA Adapter IC

The PTN3392 is a DisplayPort to VGA adapter IC designed to connect a DisplayPort source to a VGA sink. The device integrates a DisplayPort receiver and a high-speed triple video digital-to-analog converter that supports display resolutions from VGA to WUXGA. PTN3392 is designed for single supply and minimizes application costs. It can be powered directly from the DisplayPort source side at 3.3 V supply without a need for additional core voltage regulator.

Home Automation Modem dedicated to ASK Transmission

NXP’s TDA5051AT home automation modem is  specifically dedicated to ASK transmission through the means of the home power supply network. The transmission and reception stages of the device are controlled by either the master clock of the microcontroller or the on-chip reference oscillator connected to a crystal. With this, accuracy of the transmission carrier is assured and as well as the exact trimming of the digital filter, making a totally independent performance from application disturbances.

Home Automation Modem for  ASK Transmission

Where used?

  • Home appliance control
  • Energy/heating control
  • Amplitude Shift Keying data transmission

Why used?

  • Full digital carrier generation and shaping
  • Modulation/demodulation frequency set by clock adjustment
  • High clock rate of 6-bit DAC
  • Fully integrated output power stage with overload protection
  • Automatic Gain Control at Receiver input
  • Easy compliance with EN50065-1 with simple coupling network
  • Few external components for low cost applications

NXP Introduces Industry’s First Secure Total USB Type-C Solution

Total USB Type-C Solution

NXP today unveiled the industry’s most complete USB Type-C solution, including authentication and power delivery capabilities to further deliver secure connections for a smarter world. The authentication capabilities can be used to validate a device and determine whether specific functionality of that device should be enabled. This will maximize battery life and could prevent safety hazards or equipment damage from low quality materials or non-compliant products. For example, detecting counterfeit power supplies before they are used for rapid charging functions.

USB Type-C connectors are expected to become the new standard in device-to-device connectivity as they grow in popularity. Offering up to 10Gbps data rates and 100 watts of power, the USB Type-C connector and cable technology supports the growing demands of computing, mobile, and consumer products.

Improving upon the previous Type-A and Type-B USB connectors, the Type-C connector is far more user-friendly, offering reversible plug orientation, cable direction and the ability to transfer power and data simultaneously as well as support different protocols, such as DisplayPort, MHL, and Thunderbolt for alternate modes. The bi-directional power flow support allows a device to either source or sink power. In addition, Type-C connectors offer scalable power solutions, ranging from 5.0 volts at 0.5 amps for handheld devices up to 20 volts at 5.0 amps for rapid charging and power delivery.
