Product Details

The ADN4662 is a single, CMOS, low voltage differential signaling (LVDS) line receiver offering data rates of over 400 Mbps (200 MHz), and ultralow power consumption. It features a flow-through pinout for easy PCB layout and separation of input and output signals.

The device accepts low voltage (310 mV typical) differential input signals and converts them to a single-ended 3 V TTL/ CMOS logic level. The ADN4662 and its companion driver, the ADN4661, offer a new solution to high speed, point-to-point data transmission, and a low power alternative to emitter-coupled logic (ECL) or positive emitter-coupled logic (PECL).
Applications

Point-to-point data transmission

Multidrop buses

Clock distribution networks

Backplane receivers

OBSOLETE: AD-FMCMOTCON2-EBZ Evaluation Board

FMCMOTCON2

View Detailed Evaluation Kit Information

This evaluation board is obsolete and no longer recommended.

The AD-FMCMOTCON2-EBZ is a complete high performance servo system on an FPGA Mezzanine Card (FMC) board, the purpose of which is to provide a complete motor drive system demonstrating efficient and high dynamic control of three phase PMSM and induction motors up to 48V and 20A.

Two motors can be driven at the same time, each motor having its separate power supply. The system incorporates high quality power sources; reliable power, control, and feedback signals isolation; accurate measurement of motor current & voltage signals; high speed interfaces for control signals to allow fast controller response; industrial Ethernet high speed interfaces; single ended Hall, differential Hall, encoder and resolver interfaces; digital position sensors interface; flexible control with a FPGA/SoC interface.

The kit consists of two boards: a controller board and a drive board. An optional AD-DYNO2-EBZ dynamometer can also be purchased through Avnet and is intended to be an extension of the drive system.

Dynamometer System with Embedded Control

Two BLDC motors connected by a rigid couple in a dyno setup, which can be used to test real-time motor control performance.
One BLDC motor acts as an electronically adjustable load and is driven by the embedded control system. This motor can be directly connected to the FMC motor drive to get complex / active loads. The load can be driven also by the AD-FMCMOTCON2-EBZ to implement dynamic load profiles.
The other BLDC motor is driven by the FMC motor drive.
Measurement and display of load motor current
Measurement and display of load motor speed
External control using Analog Discovery and MathWorks Instrumentation Control Toolbox

Software:

Example reference designs showing how to use the platform with Xilinx^® FPGAs or SoCs and high performance control algorithms from Mathworks^® are provided together with the hardware.

Features & Benefits

This evaluation board is obsolete and no longer recommended.

The FMCMOTCON2 evaluation kit enables users to:

Model and implement motor control algorithms rapidly for high performance servo systems, incorporating system modelling and design concepts using Mathworks model based design
Reduce time needed to move a motor control system from concept to production, by providing a prototyping system to verify the hardware and control algorithms before moving to production stage.
