The AD9852ASQ is a kind of digital synthesizer. It adopts advanced DDS technology, coupled with an internal high-speed, high-performance D/A converters and a comparator to form a digitally-programmable agile synthesizer function. The typical applications include agile, L.O. frequency synthesis, programmable clock generator, FM chirp source for radar and scanning systems, test and measurement equipment, commercial and amateur RF exciter.
There are some features of AD9852ASQ as follows: (1)300 MHz internal clock rate; (2)integrated 12-bit output DACs; (3)ultrahigh-speed, 3 ps RMS jitter comparator; (4)excellent dynamic performance: 80 dB SFDR @ 100 MHz (±1 MHz) AOUT; (5)4* to 20* programmable reference clock multiplier; (6)dual 48-bit programmable frequency registers; (7)dual 14-bit programmable phase offset registers; (8)12-bit amplitude modulation and programmable; (9)shaped on/off keying function; (10)single pin FSK and PSK data interface; (11)linear or nonlinear fm chirp functions with single pin frequency "hold" function; (12)frequency-ramped FSK; (13)<25 ps RMS total jitter in clock generator mode; (14)automatic bidirectional frequency sweeping; (15)3.3 V single supply; (16)multiple power-down functions; (17)single-ended or differential input reference clock; (18)small 80-lead LQFP packaging.
The following is about the absolute maximum ratings of AD9852ASQ: (1)maximum junction temperature: 150; (2)VS: 4 V; (3)digital inputs: -0.7 V to +VS; (4)digital output current: 5 mA; (5)storage temperature: -65 to +150; (6)operating temperature: -40 to +85; (7)lead temperature (soldering 10 sec): 300; (8)maximum clock frequency: 300 MHz.
