Description
The ADC10D1000/1500 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 1.0/1.5 GSPS
(Non-DES Mode) or for a single channel up to 2.0/3.0 GSPS (DES Mode). The ADC10D1000/1500 achieves excellent accuracy and
dynamic performance while dissipating less than 2.8/3.6 Watts. The product is packaged in a leaded or lead-free 292-ball
thermally enhanced BGA package over the rated industrial temperature range of
-40°C to +85°C.
The ADC10D1000/1500 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
9.1/9.0 Effective Number of Bits (ENOB) with a 100 MHz input signal and a 1.0/1.5 GHz sample rate while providing a 10
-18 Code Error Rate (CER) Dissipating a typical 2.77/3.59 Watts in Non-Demultiplex Mode at 1.0/1.5 GSPS from a single 1.9V 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 second 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 2.0/3.0 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 Signaling (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 reduction for well-controlled back planes.
The ADC10D1500 is the latest advance in Nationals 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 1.5 GSPS (Non-DES Mode) or for a single channel up to 3.0 GSPS (DES Mode). The ADC10D1500 achieves excellent accuracy and dynamic performance while dissipating less than 3.6 Watts.
The ADC10D1500 Reference Board (ADC10D1500RB) is designed to assist in the evaluation of the ADC in a system, as well as serve as a reference design for the customers system. All that are required, in addition to the Reference Board kit, in order to use it are a PC and a signal generator for the analog input. A bandpass or lowpass filter for the analog input is also strongly recommended. This platform can be evaluated and controlled via WaveVision5 software, which has been developed for use with it. The on-board FPGA captures data from the ADC and transfers it to the PC via the USB connection. Data may be viewed in the time domain, frequency domain, or as a histogram. The ADC10D1500 control registers, which offer additional mode selection and features, may also be accessed via the WaveVision5 interface.
The features of this board are designed to allow for maximum flexibility and convenience. The analog input may be configured for AC- or DC-coupling and two balun boards of different frequency ranges are provided to achieve single-ended to differential conversion from a signal source. Nationals on-board LMX2531LQ1500E provides a sampling clock at 1.5GHz. Alternately, an external clock at a different frequency may be used for the sampling clock. A 7.5V brick supply provides power to the board and the power supply section, which regulates this supply down to the various required voltages, serves as a model for a customer system. See the Users Guide for a complete description of features.
If the ADC is being used in DESIQ Mode, a DESIQ Balun Board is available to drive the ADC externally.

The TC1 DESIQ Single Balun Board is an accessory board which is designed to drive the ADC1xD1x00RB in DESIQ Mode. It takes a single-ended signal (SMA input) and can drive the I+, I-, Q+ and Q- inputs to the Gig ADC Reference Board.
This board has the Mini-Circuits TC1-1-13MA+ balun on it, which rated performance is from 4.5 MHz to 3000 MHz.
Please note that this board cannot be used to drive the DESCLKIQ Mode. This is because the DESCLKIQ Mode requires I- and Q-channel inputs to be balanced more precisely than can be achieved by two separate boards attached by cables. Using this board to drive the DESCLKIQ Mode is functionally possible, but there will be a large interleaving spur, which cannot be minimized to achieve reasonable SFDR performance.

The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
