High PerformanceMaintains 60.1 dBFS SNR converter optimized for high performance, low power, and ease 300 MSPS with a 70 MHz input. of use. The product operates at up to a 300 MSPS conversion 2. Low PowerConsumes only 410 mW 300 MSPS. rate and is optimized for outstanding dynamic performance 3. Ease of UseLVDS output data and output clock signal in wideband carrier and broadband systems. All necessary allow interface to current FPGA technology. The on-chip functions, including a track-and-hold (T/H) and voltage reference and sample-and-hold provide flexibility in reference, are included on the chip to provide a complete system design. Use of a single 1.8 V supply simplifies signal conversion solution. system power supply design. 4. Serial Port ControlStandard serial port interface The ADC requires a 1.8 V analog voltage supply and a supports various product functions, such as data differential clock for full performance operation. The digital formatting, disabling the clock duty cycle stabilizer, power- outputs are LVDS (ANSI-644) compatible and support either down, gain adjust, and output test pattern generation. twos complement, offset binary format, or Gray code. A data 5. Pin-Compatible Family12-bit pin-compatible family clock output is available for proper output data timing. offered as AD9230. Fabricated on an advanced CMOS process, the AD9211 is available in a 56-lead LFCSP, specified over the industrial temperature range (40C to +85C).
