10-Bit, 105 MSPS/125 MSPS/150 MSPS, 1.8 V Dual Analog-to-Digital Converter AD9600 FEATURES I/Q demodulation systems SNR = 60.6 dBc (61.6 dBFS) to 70 MHz at 150 MSPS Smart antenna systems SFDR = 81 dBc to 70 MHz at 150 MSPS Digital predistortion Low power: 825 mW at 150 MSPS General-purpose software radios 1.8 V analog supply operation Broadband data applications 1.8 V to 3.3 V CMOS output supply or 1.8 V LVDS supply Data acquisition Integer 1 to 8 input clock divider Nondestructive testing Intermediate frequency (IF) sampling frequencies up to 450 MHz PRODUCT HIGHLIGHTS Internal analog-to-digital converter (ADC) voltage reference
1. Integrated dual, 10-bit, 150 MSPS/125 MSPS/105 MSPS ADC.
Integrated ADC sample-and-hold inputs
2. Fast overrange detect and signal monitor with serial output.
Flexible analog input: 1 V p-p to 2 V p-p range
3. Signal monitor block with dedicated serial output mode.
Differential analog inputs with 650 MHz bandwidth
4. Proprietary differential input maintains excellent SNR
ADC clock duty cycle stabilizer
performance for input frequencies up to 450 MHz.
95 dB channel isolation/crosstalk
5. The AD9600 operates from a single 1.8 V supply and
Serial port control
features a separate digital output driver supply to
User-configurable built-in self-test (BIST) capability
accommodate 1.8 V to 3.3 V logic families.
Energy-saving power-down modes
6. A standard serial port interface supports various product
Integrated receive features
features and functions, such as data formatting (offset
Fast detect/threshold bits
binary, twos complement, or gray coding), enabling the
Composite signal monitor
clock DCS, power-down mode, and voltage reference mode.
APPLICATIONS
7. The AD9600 is pin compatible with the AD9627-11, AD9627,
Point-to-point radio receivers (GPSK, QAM)
and AD9640, allowing a simple migration from 10 bits to
Diversity radio systems
11 bits, 12 bits, or 14 bits.
