製品概要

ADP2164は、4A、同期型、ステップダウンのDC-DC安定化電源で、小型4×4mmのLFCSPパッケージで供給されます。この製品は、電流モード、定周波数のパルス幅変調(PWM)制御を使っており、優れた安定性とトランジエント応答を実現しています。

ADP2164の入力電圧範囲は、2.7V~6.5Vです。ADP2164の出力電圧は、0.6V~入力電圧(VIN)間で調整可能となっています。また、ADP2164では、以下の6種の固定出力電圧オプションが用意されています:3.3C、2.5V、1.8V、1.5V、1.2 V、1.0V

ADP2164には、効率の最大化と外部部品数の最小化を図るために、低オン抵抗のPチャンネルとNチャンネルの内部MOSFETペアーが内蔵されています。100%のデューティ・サイクル動作は、4Aの出力電流時で、低ドロップアウト電圧を実現します。

高い1.2MHzのPWMスイッチング周波数を採用しているため、小型外部部品の使用が可能となっており、SYNC入力は、複数ICの位相同期出力が可能となり、リップルを軽減させ、ビート周波数を排除します。

ADP2164のその他の特長として、アンダーボルテージ・ロックアウト(UVLO)機能、スタートアップ時の突入電流を制限するソフトスタート機能、過電圧保護機能(OVP)、過電流保護(OCP)およびサーマル・シャットダウン機能などがあります。

EVAL-ADP2164 ブロック図

製品概要

The ADP2164 is a synchronous, step-down dc-to-dc regulator in a compact, 4 mm × 4 mm LFCSP package. The ADP2164 requires minimal external components to provide a high efficiency solution with integrated power switch, synchronous rectifier, and internal compensation. The input voltage range of the ADP2164 is 2.7 V to 6.5 V.

The ADP2164 evaluation board provides an easy way to evalu-ate the device. This user guide describes how to quickly set up the board to collect performance data.

Complete information about the ADP2164 is available in the ADP2164 data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.

EVAL-SC589-EZLITE 写真

製品概要

The ADSP-SC589 EZ-KIT Lite and EZ-Board® are evaluation systems for the ADSP-SC58x family of SHARC® processors.  The ADSP-SC589 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

AD-FMCOMMS3-EBZ ブロック図

AD-FMCOMMS3-EBZ 写真

製品概要

The AD-FMCOMMS3-EBZ is a high-speed analog module designed to showcase the AD9361, a high performance, highly integrated RF transceiver intended for use in RF applications, such as 3G and 4G base station and test equipment applications, and software defined radios. Its programmability and wideband capability make it ideal for a broad range of transceiver applications. The device combines an RF front end with a flexible mixed-signal baseband section and integrated frequency synthesizers, simplifying design-in by providing a configurable digital interface to a processor or FPGA. The AD9361 chip operates in the 70 MHz to 6 GHz range, covering most licensed and unlicensed bands. The chip supports channel bandwidths from less than 200 kHz to 56 MHz by changing sample rate, digital filters, and decimation, which re all programmable within the AD9361 itself.

The AD-FMCOMMS3-EBZ provides software developers and system architect who want a single platform to operate over a wider tuning range than the AD-FMCOMMS2-EBZ. RF performance expectations of this board must be tempered with the very wide band front end. It does meet the datasheet specifications at 2.4 GHz, but does not over the entire RF tuning range that the board supports. Typical performance data for the entire range (70 MHz – 6 GHz) which is supported by the platform is published within the board documentation. This board is primarily intended for system investigation and bringing up various waveforms from a software team before custom hardware is complete. The objective being for designers to see waveforms, but not being concerned about the last 1dB or 1% EVM of performance. For performance-oriented platforms – please refer to the AD-FMCOMMS2-EBZ.

Its programmability and wideband capability make it ideal for a broad range of transceiver applications.

The AD9361 chip operates in the 70 MHz to 6 GHz range, covering most licensed and unlicensed bands. The AD-FMCOMMS2-EBZ board comes specifically tuned and optimized to 2.4 GHz and due to the limitations of the on-board discrete external components, it may exhibit diminished RF performance on some other programmed configurations. The chip supports channel bandwidths from less than 200 kHz to 56 MHz by changing sample rate, digital filters, and decimation, all programmable within the AD9361 itself.

The AD-FMCOMMS2-EBZ provides RF engineers the ability to connect the AD9361 to a RF testbench (Vector Signal Analyzer, Signal generator, etc) and measure performance. The external components (which can easily be swapped) on the AD-FMCOMMS2-EBZ have a narrower RF tuning range 2400 – 2500 MHz. It is expected that most engineers will change these external components (pin for pin replacements from various vendors are available) for their specific application/frequency of interest. Anyone interested in a wider tuning range board should look at the AD-FMCOMMS3-EBZ.

製品概要

The AD-FMCOMMS4-EBZ provides software developers and system architect with a single 1 x 1 transceiver platform that can be software-configured for wideband tuning as well as narrowband RF performance.


In the wideband configuration, the AD-FMCOMMS4-EBZ will operate over the full 70 MHz to 6 GHz tuning range of the AD9364, however, the RF performance expectations of this configuration must be tempered with the very wide band front end. It will meet the AD9364 datasheet specifications at 2.4 GHz, but does not over the entire RF tuning range that the board can support. Typical performance data for the platform’s entire tuning range is published within the board documentation. This configuration is primarily intended for system investigation and bringing up various waveforms from a software team before custom hardware is complete. The objective being for designers to see waveforms, but not being concerned about the last 1dB or 1% EVM of performance.


The AD-FMCOMMS4-EBZ can also be user-configured for optimum performance in the 2400 – 2500 MHz band. In this configuration it may exhibit diminished RF performance on tuned frequencies or programmed configurations, outside of this band. This configuration is primarily intended to provide RF engineers with the ability to connect the AD9364 to an RF test bench (Vector Signal Analyzer, Signal generator, etc.) and achieve its optimum performance. The AD-FMCOMMS4-EBZ is a high-speed 1 x 1 agile RF transceiver analog FMC module software-tunable over the 56 MHz to 6 GHz band.
