APPLICATIONS

Communications Diversity radio systems Multimode digital receivers (3G) TD-SCDMA, WiMAX, WCDMA, CDMA2000, GSM, EDGE, LTE I/Q demodulation systems Smart antenna systems General-purpose software radios Ultrasound equipment Broadband data applications

GENERAL DESCRIPTION

The ADC features wide bandwidth inputs that can support a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer (DCS) is provided to compensate for variations in the ADC clock duty cycle, allowing the converter to maintain excellent performance.
