PRODUCT HIGHLIGHTS
1.
Two ADCs are contained in a small, space-saving,
10 mm × 10 mm × 1.4 mm, 144-ball CSP_BGA 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.
120 mW per ADC core power consumption.
5.
Operation from a single 1.8 V supply.
6.
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.
7.
On-chip integer 1-to-8 input clock divider and multichip
sync function to support a wide range of clocking schemes
and multichannel subsystems.
