MD0201 4 X 4 Cross-Point Analog Switch with 130V T/R Switches Features General Description 16 cross-point analog echo signal matrix switches The MD0201 is a low voltage analog 4x4 cross-point 130V 20ns T/R switch built-in for each channel switch with four high voltage T/R switches, voltage limit 50 total ON resistance for low insertion loss diode and output shunt switch circuit. It is designed for 0.8nV/rt.Hz low RF input noise at 5MHz medical ultrasound image system receiver beamforming DC to 100MHz small signal bandwidth applications. It also can be used in NDT and other ultrasound -55dB off-Isolation and -65dB crosstalk applications. Shunt switch for LNA fast recovery The MD0201 circuit consists of a low voltage CMOS analog Programmable auto trig levels and time switch and digital logic control serial interface circuits. 5V power supply, 2.5V to 3.3V Logic These analog switches not only have low insertion loss, 5mA low power supply consumptions low noise, and wide frequency response, they also have 20MHz serial interface high off isolation and low channel-to-channel crosstalk. The -55dB HD2 very low echo signal distortion inputs of the analog switches are connected to the output of the two terminal type of ultrasound T/R switches, and two Applications back-to-back diode voltage limiter circuits. Medical imaging ultrasound beamforming receiver Software programmable echo multiplex switching The buffered serial interface data registers have allowed the High resolution phase array ultrasound NDT IC maximum flexibility to connect large number of channels Ultrasonic phase array receiver focusing to form the echo multiplexing, dynamic-focusing circuit for Array PZT transducer echo phase processing ultrasound image receive beamforming.
