14-bit ADCs Address Requirements for Communications, Instrumentation and Test

摘要

Analog Devices released single and dual-chan-nel 14-bit high-speed A/D converters for use in communications, instru-mentation and test and measurement apphca-tions. The new converters are asserted to meet the performance and small size requirements of the latest 3G and 4G multi-standard cellular infrastructure equipment such as CDMA2000, WB-CDMA, LTE, TD-SCDMA and multi-carrier GSM. Other applications include battery-powered, hand-held instruments, scopes and portable medical devices. The AD9648 is a low-power, high-speed, 14-bit dual A/D converter that consumes 102 mW/chan-nel at 125 MSPS and features SFDR performance of 91 dBc at 70 MHz. With IF sampling frequencies up to 200 MHz, the ADC is desirable for designers looking for a dual high-speed A/D converter to build multimode digital receivers.
