Features 1.1 GHz Full Power Bandwidth Internal sample-and-hold circuit Low power consumption Internal precision 1.0V reference Single-ended or Differential clock modes Clock Duty Cycle Stabilizer Dual +3.3V and +1.8V supply operation Power-down and Sleep modes Offset binary or 2's complement output data format Pin-compatible: ADC14155, ADC11C125, ADC11C170 48-pin LLP package, (7x7x0.8mm, 0.5mm pin-pitch) Description The ADC12C170 is a high-performance CMOS analog-to-digital converter capable of converting analog input signals into 12-Bit digital words at rates up to 170 Mega Samples Per Second (MSPS). This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and the external component count, while providing excellent dynamic performance. A unique sample-and-hold stage yields a full-power bandwidth of 1.1 GHz. The ADC12C170 operates from dual +3.3V and +1.8V power supplies and consumes 715 mW of power at 170 MSPS. The separate +1.8V supply for the digital output interface allows lower power operation with reduced noise. A power-down feature reduces the power consumption to 5 mW while still allowing fast wake-up time to full operation. In addition there is a sleep feature which consumes 50 mW of power and has a faster wake-up time. The differential inputs provide a full scale differential input swing equal to 2 times the reference voltage. A stable 1.0V internal voltage reference is provided, or the ADC12C170 can be operated with an external reference. Clock mode (differential versus single-ended) and output data format (offset binary versus 2's complement) are pin-selectable. A duty cycle stabilizer maintains performance over a wide range of input clock duty cycles. The ADC12C170 is pin compatible with the ADC14155, ADC11C125 and ADC11C170. It is available in a 48-lead LLP package and operates over the industrial temperature range of −40°C to +85°C.

Description: This Design Kit is designed to ease evaluation and design-in of National Semiconductor's ADC12C170 12-bit Analog-to-Digital Converter, which operates at speeds up 170 Msps. This Design Kit is intended for use with input frequencies greater than 150 MHz. The evaluation board can be used in either of two modes. In the Manual mode, suitable test equipment can be used with the board to evaluate the ADC12C170 performance. In the Computer mode, evaluation is simplified by connecting the board to the WaveVision Data Capture Board (order number WAVEVSN BRD 4.0 or later), which is connected to a personal computer through a USB port and running WaveVision 4.3 software, operating under Microsoft Windows. The software can perform an FFT on the captured data upon command and, in addition to a frequency domain plot, shows dynamic performance in the form of SNR, SINAD, THD, SFDR and ENOB.
