ISLA112P25M FN7646
Rev 1.00
November 17, 2011 Low Power 12-Bit, 250MSPS ADC
The ISLA112P25MREP is a low-power 12-bit, 250MSPS
analog-to-digital converter. Designed with Intersil’s
proprietary FemtoChargeв„ў technology on a standard
CMOS process. Features A serial peripheral interface (SPI) port allows for
extensive configurability, as well as fine control of
various parameters such as gain and offset. 60fs Clock Jitter Digital output data is presented in selectable LVDS or
CMOS formats. The ISLA112P25MREP is available in a
72 Ld QFN package with an exposed paddle. Operating
from a 1.8V supply, performance is specified over the
full military temperature range (-55°C to +125°C). Clock Phase Selection Programmable Gain, Offset and Skew Control 1.3GHz Analog Input Bandwidth Over-Range Indicator Selectable Clock Divider: 1, 2 or 4 Nap and Sleep Modes Two’s Complement, Gray Code or Binary Data
