The HMC881A is a monolithic microwave integrated circuit (MMIC) low-pass filter that features a user-selectable cutoff frequency. The cutoff frequency can be varied from 2.4 GHz to 4 GHz by applying a single analog tuning voltage between 0 V and 14 V. This low-pass filter provides a low 3 dB insertion loss, 16.5 dB return loss, and 1.35 ? f3dB stopband attenuation of >20 dB. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. The HMC881A has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications. The low-pass tunable filter is packaged in a RoHS compliant 5 mm ? 5 mm LFCSP package.Applications Testing and measurement equipment Military radar and electronic warfare/electronic countermeasures (ECMs) Satellite communication and space Industrial and medical equipment

It features the processor, memory, and power portions of the design and provides an easy-to-use plug-n-play reference design with all the key interfaces made available on three connectors for marrying to either the EV-SOMCRR-EZKIT carrier board or a custom carrier board. The EV-21569-SOM and EV-SOMCRR-EZKIT boards may be purchased as a bundle (EV-21569-EZKIT), providing fast and easy evaluation of the processor core and system peripherals/interfaces. The EV-21569-SOM module requires the CrossCore® Embedded Studio (CCES) development tools to enable developers to achieve faster time to market. 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 When used without the EV-SOMCRR-EZKIT carrier board, the EV-21569-SOM board requires an external in-circuit emulator (ICE-1000 or ICE-2000) be connected to the JTAG header.

The EV-21593-SOM enables evaluation and rapid prototyping of designs featuring the ADSP-2159x Family (ADSP-21591/ADSP-21593) of SHARC audio processors. It provides an easy-to-use plug-n-play reference design with expansion capabilities to interface to custom hardware ahead of the release of the processor itself. When the EV-21593-SOM board is plugged into the EV-SOMCRR-EZKIT carrier board, the resulting EZ-KIT® evaluation system (EV-21593-EZKIT) can be used for fast and easy evaluation of the processor core and system peripherals/interfaces. The EV-21593-SOM enables rapid prototyping for a wide range of applications, including immersive 3D sound and personal audio zones (PAZ), automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications (ICC), engine sound synthesis (ESS) and electric vehicle warning sound systems (EVWSS/AVAS). Additional applications include professional audio and soundbars / home AVRs (with 3D Object and Multi-Channel Audio) and enhanced conferencing systems. ADI offers several software modules (e.g., AEC/NR, microphone beamforming, pitch shifting, harmonic generators, wave players etc.), as well as complete software solutions that can be licensed, where users can develop/evaluate their audio and voice processing applications. ADI also offers 3rd party surround sound solutions that can be licensed on ADI’s SHARC processor families. Please visit ADI’s Software Solutions page for more information.

The LT6604-15 consists of two matched, fully differential amplifiers, each with a 4th order, 15MHz lowpass ?lter. The ?xed frequency lowpass ?lter approximates a Chebyshev response. By integrating a ?lter and a differential amplifier, distortion and noise are made exceptionally low. At unity gain, the measured in band signal-to-noise ratio is an impressive 76dB. At higher gains, the input referred noise decreases, allowing the part to process smaller input differential signals without significantly degrading the signal-to-noise ratio.Gain and phase are highly matched between the two channels. Gain for each channel is independently programmed using two external resistors. The LT6604-15 enables level shifting by providing an adjustable output common mode voltage, making it ideal for directly interfacing to ADCs.The LT6604-15 is fully specified for 3V operation. The differential design enables outstanding performance at a 2VP-P signal level for a single 3V supply.

Demonstration circuit DC266B-A is for the evaluation of 8th order filter circuits using an LTC1562 (no dash) and DC266B-B for an LTC1562-2. LTC1562 and LTC1562-2 are quad 2nd order active-RC filter building blocks. Each 2nd order section has an integrator trimmed with internal capacitors and resistors to 100kHz and 200 kHz for the LTC1562 and LTC1562-2 respectively. The trimmed frequency error is ±0.6% for the LTC1562A and ±1.5% for the LTC1562-2. The LTC1562 or LTC1562-2 2nd order sections can be configured with external resistors to implement lowpass, bandpass or highpass filters.
