The ADP170 / ADP171 / ADP172 are low voltage input, low quiescent current, low-dropout (LDO) linear regulators that operate from 1.6 V to 3.6 V and provide up to 300 mA of output current. The low 55 mV dropout voltage at 300 mA load improves efficiency and allows operation over a wide input voltage range. The low 23 μA of quiescent current at no load makes the ADP170 / ADP171 / ADP172 ideal for battery-operated portable equipment.

The ADP170 is capable of 31 fixed-output voltage options, ranging from 0.8 V to 3.0 V. ADP171 is an adjustable version, which allows output voltages that range from 0.8 V to 3.0 V via an external divider. The ADP170 / ADP171 are optimized for stable operation with small 1 μF ceramic output capacitors. Ideal for powering digital processors, the ADP170 / ADP171 exhibit good transient performance and occupy minimal board space. Compared with commodity types of LDOs, the ADP170 / ADP171 provide 20 dB to 40 dB better power supply rejection ratio (PSRR) at 100 kHz, making the ADP170 / ADP171 an ideal power source for analog-to-digital converter (ADC) mixed-signal processor systems and allowing use of smaller size bypass capacitors. In addition, low output noise performance without the need for an additional bypass capacitor further reduces printed circuit board (PCB) component count.

Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. The ADP170 / ADP171 are available in tiny 5-lead TSOT for the smallest footprint solution to meet a variety of portable power applications.

ADMV96S-WGBE-EK1

60 GHz Wireless Connector

60 GHz Wireless Connector

Features and Benefits

  • Allows evaluation and prototyping of 60 GHz wireless data links to replace traditional mechanical connectors in moving joints
  • 1 Gbps Ethernet interface on both sides of the wireless data link
  • Fully programmable system allowing ultimate flexibility for custom developments
  • Open-source software stack for firmware development  
  • Open-source GUI for system configuration, monitoring, and control

Product Detail

The ADMV96S-WGBE-EK1 is a complete evaluation and prototyping system for 60 GHz wireless data links. It consists of a pair of receiver and transmitter boards with a 1Gbp Ethernet interface on each side of the wireless link.

The 60 GHz wireless link is implemented by the ADMV9615 and ADMV9525 modules. These are coupled with a SerDes device which translates the modules’ SGMII interface to RGMII so that it can be connected to an ADIN1300 industrial low latency and low power 1 Gbps Ethernet PHY. This enables each side of the wireless link to act as an Ethernet port and essentially create a seamless wire-like connection between two ends of an Ethernet cable.

The on-board MAX32650 ultralow power ARM® Cortex®-M4 microcontroller controls the system’s operation and implements the algorithms to configure the wireless link in real time so that optimal link quality is constantly maintained over temperature and various operating conditions. An open-source software stack is provided for firmware development as well as reference applications. The MAX32650 can be programmed through a programming port which can also be used for firmware debugging.

The two sides of the wireless link are mounted on an adjustable rail so that the system can be configured and tested for various distances between the links. Each side of the link is powered from an external 12 V power supply.

An open-source GUI is provided for system configuration, monitoring, and control from a host PC.

APPLICATIONS

  • 60 GHz wireless data links for industrial and medical high data rate applications
  • High speed data for rotating applications, such as slip rings and magnetic resonance imaging systems
  • Autonomous guided vehicles
  • Mechanical Connector replacement

Product Detail

The ADSP-SC584 EZ-KIT Lite and EZ-Board® are evaluation systems for the ADSP-SC58x family of SHARC® processors. The ADSP-SC584 processor is based on the SHARC+ core dual processor with the arm® Cortex-A5 processor core and is designed for a wide array of markets, from automotive and pro-audio to industrial-based applications that require high floating-point performance. The EZ-Board is shipped with all of the necessary hardware—you can start the evaluation immediately. The package contains the standalone evaluation board, CE-approved power supply, and USB cable. The EZ-KIT Lite® version ships with two 180 day licenses for CrossCore® Embedded Studio (CCES) and the ICE-1000 emulator, while the EZ-Board version requires the customer to provide an ICE-1000 or ICE-2000 emulator.

Expansion Interface III connectors are provided for interfacing with additional extender boards to provide LCD, camera, video, and audio. Traditional mechanical switches for changing the board's factory setup have been removed in favor of I2C controlled software switches. The only remaining mechanical switches are the boot mode switch, JTAG configuration switches, and push buttons.

The evaluation board is designed to be used in conjunction with the CrossCore® Embedded Studio (CCES) development tools to test capabilities of the ADSP-SC58x processors. The development environment aids advanced application code development and debug, such as:

  • Create, compile, assemble, and link application programs written in C++, C, and assembly
  • Load, run, step, halt, and set breakpoints in application programs
  • Read and write data and program memory
  • Read and write core and peripheral registers
