Energy-saving power-down modes PRODUCT HIGHLIGHTS Data clock out with programmable clock and data 1. The AD9204 operates from a single 1.8 V analog power alignment supply and features a separate digital output driver supply APPLICATIONS to accommodate 1.8 V to 3.3 V logic families. Communications 2. The patented sample-and-hold circuit maintains excellent Diversity radio systems performance for input frequencies up to 200 MHz and is Multimode digital receivers designed for low cost, low power, and ease of use. GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX, TD-SCDMA 3. A standard serial port interface supports various product I/Q demodulation systems features and functions, such as data output formatting, Smart antenna systems internal clock divider, power-down, DCO/DATA timing Battery-powered instruments and offset adjustments, and voltage reference modes. Handheld scope meters 4. The AD9204 is packaged in a 64-lead RoHS compliant Ultrasound LFCSP that is pin compatible with the AD9268 16-bit Radar/LIDAR ADC, the AD9251 and AD9258 14-bit ADCs, and the PET/SPECT imaging AD9231 12-bit ADC, enabling a simple migration path between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS.
