KAD5514P Preliminary
14-bit,www.DataSheet4U.com 250/210/170/125MSPS A/D Converter
General Description
The KAD5514P is a family of low-power, high-
performance 14-bit, analog-to-digital converters.
Designed with Kenet’s proprietary FemtoCharge®
technology on a standard CMOS process, the family
supports sampling rates of up to 250MSPS. The
KAD5514P is part of a pin-compatible portfolio of 10,
12 and 14-bit A/Ds with sample rates ranging from
125MSPS to 500MSPS.
A serial peripheral interface (SPI) port allows for
extensive configurability, as well as fine control of
various parameters such as gain and offset.
Digital output data is presented in selectable LVDS
or CMOS formats. The KAD5514P is available in 72-
and 48-contact QFN packages with an exposed
paddle. Performance is specified over the full
industrial temperature range (-40 to +85°C).
Features
• Programmable gain and offset control
• 950MHz analog input bandwidth
• 52fs Clock Jitter
• Over-range indicator
• Selectable Clock Divider: ÷1, ÷2 or ÷4
• Clock Phase Selection
• Nap and Sleep modes
• Two’s complement, Gray code or Binary data
format
• SDR/DDR LVDS-compatible or LVCMOS outputs
• Programmable Built-in Test Patterns
• 1.8V Analog and Digital Supplies
Applications
• Power Amplifier Linearization
• Radar and Satellite Antenna Array Processing
• Broadband Communications
