Rev. 0 | Page 3 of 36
When the NSR block is disabled, the ADC data is provided directly
to the output at a resolution of 11 bits. The AD6643 can achieve
up to 66.5 dBFS SNR for the entire Nyquist bandwidth when
operated in this mode. This allows the AD6643 to be used in
telecommunication applications such as a digital predistortion
observation path where wider bandwidths are required.
After digital signal processing, multiplexed output data is
routed into two 11-bit output ports such that the maximum
data rate is 400 Mbps (DDR). These outputs are LVDS and
support ANSI-644 levels.
The AD6643 receiver digitizes a wide spectrum of IF frequencies.
Each receiver is designed for simultaneous reception of a separate
antenna. This IF sampling architecture greatly reduces compo-
nent cost and complexity compared with traditional analog
techniques or less integrated digital methods.
Flexible power-down options allow significant power savings.
Programming for device setup and control is accomplished
using a 3-wire SPI-compatible serial interface with numerous
modes to support board level system testing.
The AD6643 is available in a Pb-free, RoHS compliant, 64-lead,
9 mm × 9 mm lead frame chip scale package (LFCSP_VQ) and is
specified over the industrial temperature range of −40°C to +85°C.
This product is protected by a U.S. patent.
PRODUCT HIGHLIGHTS
1.
Two ADCs are contained in a small, space-saving,
9 mm × 9 mm × 0.85 mm, 64-lead LFCSP package.
2.
Pin selectable noise shaping requantizer (NSR) function
that allows for improved SNR within a reduced bandwidth
of up to 60 MHz at 185 MSPS.
3.
LVDS digital output interface configured for low cost
FPGA families.
4.
Operation from a single 1.8 V supply.
5.
Standard serial port interface (SPI) that supports various
product features and functions, such as data formatting
(offset binary or twos complement), NSR, power-down,
test modes, and voltage reference mode.
6.
On-chip integer 1-to-8 input clock divider and multichip
sync function to support a wide range of clocking schemes
and multichannel subsystems.
