ADI AD9670BBCZ

148150 мВтПоверхностный монтаж144-LFBGA, CSPBGA

Overview

The AD9670BBCZ is designed for low cost, low power, small size, andease of use for medical ultrasound applications. It contains eightchannels of a VGA with an LNA, a CW harmonic rejection I/Qdemodulator with programmable phase rotation, an antialiasingfilter, an ADC, and a digital demodulator and decimator for dataprocessing and bandwidth reduction.

Power-down of individual channels is supported to increasebattery life for portable applications. Standby mode allows quickpower-up for power cycling. In CW Doppler operation, theVGA, antialiasing filter, and ADC are powered down. The ADCcontains several features designed to maximize flexibility andminimize system cost, such as a programmable clock, dataalignment, and programmable digital test pattern generation.The digital test patterns include built-in fixed patterns, built-inpseudorandom patterns, and custom user-defined test patternsentered via the SPI.
