AD9648BCPZ-105

AD9648 is a monolithic, dual-channel, 14bit, 105MSPS ADC. The ADC contains several features designed to maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable digital test pattern generation. The available digital test patterns include built-in deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port interface (SPI). A differential clock input controls all internal conversion cycles. An optional duty cycle stabilizer (DCS) compensates for wide variations in the clock duty cycle while maintaining excellent overall ADC performance. Typical applications include communications, diversity radio systems, multimode digital receivers (3G) (GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX, TD-SCDMA), I/Q demodulation systems, smart antenna systems, broadband data applications, battery-powered instruments, hand-held scope meters, portable medical imaging, ultrasound and radar/LIDAR.
