The KAD5510P is a family of low power, high performance
10-bit analog-to-digital converters. Designed with Intersil’s
proprietary FemtoCharge™ technology on a standard CMOS
process, the family supports sampling rates of up to
250MSPS. The KAD5510P is part of a pin-compatible portfolio
of 10-, 12- and 14-bit A/Ds with sample rates ranging from
125MSPS to 500MSPS.
Features
• 1.5GHz analog input bandwidth
• 60fs clock jitter
• Programmable gain, offset and skew control
• Over-range indicator
• Selectable clock divider: 1, 2 or 4
• Clock phase selection
A Serial Peripheral Interface (SPI) port allows for extensive
configurability, as well as fine control of various parameters
such as gain and offset.
• Nap and sleep modes
Digital output data is presented in selectable LVDS or CMOS
formats. The KAD5510P is available in a 48 Ld QFN package
with an exposed paddle. Operating from a 1.8V supply,
performance is specified across the industrial operating
temperature range (-40°C to +85°C).
• Two’s complement, gray code or binary data format
• DDR LVDS-compatible or LVCMOS outputs
• Programmable built-in test patterns
• Single-supply 1.8V operation
• Pb-free (RoHS compliant)
