製品概要

ADP1754 / ADP1755は、低ドロップアウト(LDO)のCMOSリニア・レギュレータであり、1.6V~3.6Vで動作し、最大出力電流は1.2Aです。

これらのVin / Voutの低いLDOは、2.5V~1.8VのI/Oレールで動作して、0.75Vと低いコア電圧を供給するナノメータ・サイズFPGAのレギュレーションに最適です。ADP1754 / ADP1755は当社独自の最新アーキテクチャを採用し、高い電源除去比(PSRR)と低ノイズを提供し、小型の4.7μFセラミック出力コンデンサを使うだけで、優れたライン過渡応答と負荷過渡応答を実現します。ADP1754は、7種類の固定出力電圧オプションを提供しています。ADP1755は調整可能なバージョンで、外付け分圧器を使って0.75V~3.3Vの範囲の出力電圧が可能です。ADP1754 / ADP1755では、スタートアップを設定する外付けソフトスタート・コンデンサを接続することができます。デジタルの電源正常表示出力を使うと、電源システム・モニタに出力電圧の状態をチェックさせることができます。

ADP1754 / ADP1755は16ピンの4mm×4mm LFCSPパッケージを採用しているため、非常に小型なソリューションであるだけでなく、小型なロー・プロファイル・フットプリントで1.2Aまでの出力電流を必要とするアプリケーションに対して優れた熱性能も提供します。

製品概要

These evaluation boards are used to demonstrate the functionality of the ADP1754/ADP1755 linear regulators.


Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.

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.
