DATASHEET
ISLA222P FN7853
Rev 1.00
June 17, 2011 Dual 12-Bit, 250MSPS/200MSPS/130MSPS ADC
The ISLA222P is a family of dual-channel 12-bit
analog-to-digital converters. Designed with Intersil’s
proprietary FemtoChargeв„ў technology on a standard CMOS
process, the family supports sampling rates of up to
250MSPS. The ISLA222P is part of a pin-compatible portfolio
of 12-bit and 14-bit dual-channel A/Ds with maximum sample
rates ranging from 130MSPS to 250MSPS. Features A serial peripheral interface (SPI) port allows for extensive
configurability, as well as fine control of various parameters
such as gain and offset. Programmable Built-in Test Patterns Digital output data is presented in selectable LVDS or CMOS
formats. The ISLA222P is available in a 72 lead QFN package
with an exposed paddle. Operating from a 1.8V supply,
performance is specified over the full industrial temperature
range (-40В°C to +85В°C). Single Supply 1.8V Operation Clock Duty Cycle Stabilizer 75fs Clock Jitter 700MHz Bandwidth Multi-ADC Support
