Low Power, 10-Bit, Dual 1.0 GSPS or Single 2.0 GSPS ADC
1.0 General Description
The ADC10D1000 is the latest advance in National's Ultra-
High-Speed ADC family. This low-power, high-performance
CMOS analog-to-digital converter digitizes signals at 10-bit
resolution for dual channels at sampling rates of up to 1.0
GSPS (Non-DES Mode) or for a single channel up to 2.0
GSPS (DES Mode). The ADC10D1000 achieves excellent
accuracy and dynamic performance while dissipating less
than 2.8 Watts. The product is packaged in a leaded or lead-
free 292-ball thermally enhanced BGA package which does
not require a heat sink over the rated industrial temperature
range of -40°C to +85°C.
The ADC10D1000 builds upon the features, architecture and
functionality of the 8-bit GHz family of ADCs. An expanded
feature set includes AutoSync for multi-chip synchronization,
15-bit programmable gain and 12-bit plus sign programmable
offset adjustment for each channel. The improved internal
track-and-hold amplifier and the extended self-calibration
scheme enable a very flat response of all dynamic parameters
beyond Nyquist, producing 9.0 Effective Number of Bits
(ENOB) with a 498 MHz input signal and a 1.0 GHz sample
rate while providing a 10^-18 Code Error Rate (CER) Dissipat-
ing a typical 2.77 Watts in Non-Demultiplex Mode at 1.0
GSPS from a single 1.9 Volt supply, this device is guaranteed
to have no missing codes over the full operating temperature
range.
Each channel has its own independent DDR Data Clock,
DCLKI and DCLKQ, which are in phase when both channels
are powered up, so that only one Data Clock could be used
to capture all data, which is sent out at the same rate as the
input sample clock. If the 1:2 Demux Mode is selected, a sec-
ond 10-bit LVDS bus becomes active for each channel, such
that the output data rate is sent out two times slower to relax
data-capture timing requirements. The part can also be used
as a single 2.0 GSPS ADC to sample one of the I or Q inputs.
The output formatting can be programmed to be offset binary
or two's complement and the Low Voltage Differential Signal-
ing (LVDS) digital outputs are compatible with IEEE
1596.3-1996, with the exception of an adjustable common
mode voltage between 0.8V and 1.2V to allow for power re-
duction for well-controlled back planes.
