Features Clock Duty Cycle Stabilizer Single +3.0V or 3.3V supply operation Serial LVDS Outputs Serial Control Interface Overrange outputs 60-pin LLP package, (9x9x0.8mm, 0.5mm pin-pitch) Description The ADC14DS105CISQ and ADC14DS105AISQ are high-performance CMOS analog-to-digital converters capable of converting two analog input signals into 14-bit digital words at rates up to 105 Mega Samples Per Second (MSPS). The digital outputs are serialized and provided on differential LVDS signal pairs. Both parts provide excellent performance, however, the ADC14DS105AISQ offers higher SFDR. These converters use 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. The ADC14DS105 may be operated from a single +3.0V or 3.3V power supply. A power-down feature reduces the power consumption to very low levels while still allowing fast wake-up time to full operation. The differential inputs accept a 2V full scale differential input swing. A stable 1.2V internal voltage reference is provided, or the ADC14DS105 can be operated with an external 1.2V reference. The selectable duty cycle stabilizer maintains performance over a wide range of clock duty cycles. A serial interface allows access to the internal registers for full control of the ADC14DS105's functionality. The ADC14DS105 is available in a 60-lead LLP package and operates over the industrial temperature range of −40°C to +85°C.

RD-147: ADC14V155/LMH6552/LMK02000 Low IF Receiver Reference Design Files & Documentation Description: This Reference Design Kit is designed to demonstrate a low IF receiver subysystem, commonly used in WiMAX and WCDMA receivers. The reference design uses the following products from National Semiconductor`s PowerWise® family of products: Two LMH6552 1.5 GHz bandwidth differential current feedback amplifiers; ADC14DS105 14-bit, 1 GHz, Dual 105 MSPS (Megasample per Second) ADC with serial LVDS outputs; LMK02000 low-jitter precision clock conditioner with an integrated phase-locked loop (PLL) that provides 128 femtosecond (fs) jitter over an integration bandwidth of 100 Hz to 20 MHz; Several energy-efficient power management ICs. The reference board is designed for evaluation at input frequencies up to 35 MHz with a sampling frequency of 100 MSPS. The sampling frequency is generated on the board by a 100 MHz VCXO which is locked to a reference oscillator by the LMK02000. 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 reference design performance. In the Computer mode, evaluation is simplified by connecting the board to the WaveVision 5.1 Data Capture Board (order number WAVEVSN BRD 5.1), which is connected to a personal computer through a USB port and running WaveVision 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. Features: Board comes fully assembled and tested Single (+5V) supply needed All ADC features can be exercised Contents: Evaluation Board User`s Guide PIC microcontroller module for programming the LMK02000 CD with WaveVision Software
