ISLA214P50 FN7571
Rev 2.00
December 10, 2012 14-Bit, 500MSPS ADC
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.
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.
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.
Digital output data is presented in selectable LVDS or CMOS
formats. The ISLA214P50 is available in a 72 Ld QFN package …
