Synchronisation of giga-sample ADCs for phased array radar systems

Synchronisation of giga-sample ADCs for phased array radar systems
This system level design shows how two ADC12J4000 evaluation modules (EVMs) can be synchronised together using a Xilinx VC707 platform. The design document describes the required hardware modifications and device configurations, including the clocking scheme. Example configuration files are shown for each EVM.

Three-phase inverter reference design for VAC drives

Three-phase inverter reference design for VAC drives
This reference design from TI realises a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. The UCC23513 gate driver used has a six-pin wide body package with optical LED emulated inputs which enables its use as pin-to-pin replacement to existing opto-isolated gate drivers.

Pulse-width-modulation control circuit on a single chip

Pulse-width-modulation control circuit on a single chip
The TL494 device from Texas Instruments incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application.

Analog front end reference design for high-speed oscilloscope

Analog front end reference design for high-speed oscilloscope
This reference design provides a practical example of interleaved RF-sampling analog-to-digital converters (ADCs) to achieve a 12.8-GSPS sampling rate. This is achieved by time-terleaving two RF-sampling ADCs. Interleaving requires a phase shift between the ADCs, which this reference design achieves using the Noiseless Aperture Delay Adjustment (tAD Adjust) feature of the ADC12DJ3200.

Understanding and overcoming IoT software development challenges

Understanding and overcoming IoT software development challenges
The rapid growth of the IoT market has put huge pressure on software development process. Not only do connected devices need to be brought to market fast, be cost effective and work efficiently, they often also require regular software updates, and in many cases, to comply with safety and security standards. By Chuck Gehman, Perforce Software.

Design, optimise and simulate an active filter within minutes

Design, optimise and simulate an active filter within minutes
You are on a quest to design an active filter. You have the specifications of the filter’s frequency response, but how do you create a circuit that does just what you want? If you took the conventional approach, you would need to manipulate the second-order control system equations by consulting multiple filter-response coefficient tables.

Design tool to optimise filter solutions

Design tool to optimise filter solutions
Active filters are vital in modern electronics; every data acquisition systems need them for bandwidth-limiting signals before ADCs as anti-aliasing filters, or after DACs as anti-imaging filters. Instrumentation also relies on them for accurate signal measurements.

What are isolated digital inputs?

What are isolated digital inputs?
Digital isolators serve the basic (or often reinforced!) function of providing galvanic isolation digital signal paths. TI isolation structures are capacitive, with the insulation barrier consisting of two high-voltage capacitors built from our complementary metal-oxide semiconductor (CMOS) process technology.
