July 25, 2011 10-Bit, 500MSPS A/D Converter
The ISLA110P50 is a low-power, high-performance, 500MSPS
analog-to-digital converter designed with Intersil’s proprietary
FemtoChargeв„ў technology on a standard CMOS process. The
ISLA110P50 is part of a pin-compatible portfolio of 8, 10 and
12-bit A/Ds. This device is an upgrade of the KAD551XP-50
product family and is pin similar.
The device utilizes two time-interleaved 250MSPS unit A/Ds 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 fine
correction of offset, gain, and sample time skew mismatches
between the unit A/Ds to optimize performance. No external
interleaving algorithm is required. Features 1.15GHz Analog Input Bandwidth 90fs Clock Jitter Automatic Fine Interleave Correction Calibration Multiple Chip Time Alignment Support via the Synchronous
Clock Divider Reset Programmable Gain, Offset and Skew Control Over-Range Indicator Clock Phase Selection Nap and Sleep Modes Two’s Complement, Gray Code or Binary Data Format 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 continuous
calibration commands as well as configure many dynamic
parameters. DDR LVDS-Compatible or LVCMOS Outputs Digital output data is presented in selectable LVDS or CMOS …
