  • Description

    The ADC08D1500 is a dual, low power, high performance CMOS analog-to-digital converter that digitizes signals to 8 bits resolution at sample rates up to 1.7 GSPS. Consuming a typical 1.8 Watts at 1.5 GSPS from a single 1.9 Volt supply, this device is guaranteed to have no missing codes over the full operating temperature range. The unique folding and interpolating architecture, the fully differential comparator design, the innovative design of the internal sample-and-hold amplifier and the self-calibration scheme enable a very flat response of all dynamic parameters beyond Nyquist, producing a high 7.25 ENOB with a 748 MHz input signal and a 1.5 GHz sample rate while providing a 10 -18 C.E.R. Output formatting is binary and the 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.

    Each converter has a 1:2 demultiplexer that feeds two LVDS buses and reduces the output data rate on each bus to half the sample rate. The two converters can be interleaved and used as a single 3 GSPS ADC.

    The converter typically consumes less than 3.5 mW in the Power Down Mode and is available in a 128-lead, thermally enhanced exposed pad LQFP and operates over the Industrial (-40°C TA +85°C) temperature range.

    Description:
    ADC08D1500DEV - Dual 8-Bit, 1.5 GSPS, 1.8W A/D Converter with Xilinx Virtex 4 (XC4VLX15) FPGA
    The ADC08D1500DEV Development System is designed to allow quick evaluation and design development of National Semiconductor's ADC08D1500 8-bit Analog-to-Digital Converter. This device is specified for 1.5 GSPS operation in 2 channel mode or it can be configured as a 3 GSPS Converter in Dual Edge Sampling mode (DES).
    This development board is designed to function with National Semiconductors WaveVision Software, for fast evaluation. It requires only 3 connections to get started: a Power Supply, a USB Interface to PC and a Signal Source. A 1.5GHz Clock generator is provided on board and the system also allows an external clock to be used if alternative sample rates are required.
    The ADC connects to a Xilinx Virtex4 FPGA which stores up to 4K of data from each channel before transferring it through the USB interface to the PC.

    A Development System for the single-channel ADC081500 is not available. Instead, use the ADC08D1500 and power down one channel.

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
