Rev 2.00
January 25, 2013 12-Bit, 500MSPS ADC
The ISLA212P50 is a 12-bit, 500MSPS analog-to-digital
converter designed with Intersil’s proprietary FemtoCharge™
technology on a standard CMOS process. The ISLA212P50 is
part of a pin-compatible portfolio of 12 to 16-bit A/Ds with
maximum sample rates ranging from 130MSPS to 500MSPS. Features 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. 75f clock jitter 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 ISLA212P50 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 …
