14-Bit, 500MSPS ADC  
ISLA214P50  
Features  
• Automatic Fine Interleave Correction Calibration  
• Single Supply 1.8V Operation  
• Clock Duty Cycle Stabilizer  
The ISLA214P50 is a 14-bit, 500MSPS analog-to-digital converter  
designed with Intersil’s proprietary FemtoCharge™ technology on  
a standard CMOS process. The ISLA214P50 is part of a  
pin-compatible portfolio of 12 to 16-bit A/Ds with maximum  
sample rates ranging from 130MSPS to 500MSPS.  
• 75fs Clock Jitter  
• 700MHz Bandwidth  
The device utilizes two time-interleaved 250MSPS unit ADCs 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 (I2E) performs automatic correction of offset, gain, and  
sample time mismatches between the unit ADCs to optimize  
performance.  
• Programmable Built-in Test Patterns  
• Multi-ADC Support  
- SPI Programmable Fine Gain and Offset Control  
- Support for Multiple ADC Synchronization  
- Optimized Output Timing  
A serial peripheral interface (SPI) 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.  
• Nap and Sleep Modes  
- 200µs Sleep Wake-up Time  
• Data Output Clock  
• DDR LVDS-Compatible or LVCMOS Outputs  
• User-accessible Digital Temperature Monitor  
Digital output data is presented in selectable LVDS or CMOS  
formats. The ISLA214P50 is available in a 72 Ld QFN package  
with an exposed paddle. Operating from a 1.8V supply,  
performance is specified over the full industrial temperature  
range (-40°C to +85°C).  
Applications  
• Radar Array Processing  
• Software Defined Radios  
• Broadband Communications  
• High-Performance Data Acquisition  
• Communications Test Equipment
