KAD5512P-50 Preliminary
12-Bit, 500MSPS A/D Converter
General Description
The KAD5512P-50 is a low-power, high-performance,
12-bit, 500MSPS analog-to-digital converter
designed with Kenet’s proprietary FemtoCharge^®
technology on a standard CMOS process. The
KAD5512P-50 is part of a pin-compatible portfolio of
10, 12 and 14-bit A/Ds with sample rates ranging
from 125MSPS to 500MSPS.
The device utilizes two time-interleaved 12-bit,
250MSPS A/D cores 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.
A serial peripheral interface (SPI) port allows for
extensive configurability, as well as fine control of
matching characteristics (gain, offset, skew)
between the two converter cores. These
adjustments allow the user to minimize spurs
associated with the interleaving process.
Digital output data is presented in selectable LVDS
or CMOS formats. The KAD5512P-50 is available in a
72-contact QFN package with an exposed paddle.
Performance is specified over the full industrial
temperature range (-40 to +85°C).
