Download Technical Datasheet

The ISLA214P50IRZ is a 14-bit Analog-to-digital Converter (ADC) designed with Intersils proprietary FemtoCharge™ technology on a standard CMOS process. The device utilizes two time-interleaved 250MSPS unit ADC to achieve the ultimate sample rate of 500MSPS. A single 500MHz conversion clock is presented to the converter and all interleave clocking is managed internally. The proprietary Intersil Interleave Engine performs automatic correction of offset, gain and sample time mismatches between the units ADC to optimize performance. A serial peripheral interface port allows for extensive configurability of the A/D. The SPI also controls the interleave correction circuitry, allowing the system to issue offline and continuous calibration commands as well as configure many dynamic parameters.

  • Automatic fine interleave correction calibration
  • Clock duty cycle stabilizer
  • Programmable built-in test patterns
  • SPI programmable fine gain and offset control
  • Support for multiple ADC synchronization
  • Optimized output timing
  • Nap and sleep modes
  • Data output clock
  • DDR LVDS-compatible or LVCMOS outputs
  • Selectable clock divider
