ADC11C170CISQ/NOPB 概述
An ADC (analog-to-digital converter) is a semiconductor device that converts continuous analog signals into discrete digital words, and a pipelined ADC is a high-speed architecture that processes samples through cascaded low-resolution stages to achieve high sample rates while maintaining moderate resolution. The ADC11C170 sits within the broader hierarchy: ADC -> data converter -> signal-chain IC -> mixed-signal semiconductor. This pipelined subfamily is favored in applications where conversion rate matters more than absolute resolution, such as digital oscilloscopes, software-defined radio, and IF sampling in wireless receivers.
Key features include 11-bit resolution, 170 MSPS sampling rate, 1.1 GHz analog input bandwidth suitable for undersampling of IF signals, single 1.8 V supply operation for the analog domain, CMOS digital outputs operating at 1.8 V (with optional level-shift via external PLD as shown in the TI evaluation kit), and an industrial -40C to +85C operating temperature range. The 48-WQFN package with exposed pad provides low thermal resistance for dissipating the typical power consumption at 170 MSPS operation.
The pipelined architecture performs bit-decision and residue amplification across multiple clocked stages, achieving one conversion per clock cycle after pipeline latency. Internal reference and sample-and-hold circuits are integrated. CMOS outputs simplify interface to FPGAs and ASICs without requiring level translation in 1.8 V systems.
Typical applications include high-IF undersampling in software-defined radio, IF digitizing in cable infrastructure, set-top box and digital-pre-vision receivers, medical imaging front-ends, and digitizing oscilloscope input stages. The wide 1.1 GHz analog bandwidth allows the converter to sample second or third Nyquist zones, replacing mixer-plus-baseband-ADC chains with a single component.
When designing with this device, observe proper analog-input driving through a differential amplifier (e.g., LMH6554) and provide a low-jitter clock source, as aperture jitter directly limits SNR at high input frequencies. Decouple AVDD and DVDD separately and tie the exposed pad to a clean analog ground.

典型应用
ADC11C170CISQ/NOPB 适用于 6 应用s: Software-Defined Radio IF Sampling, Digital Oscilloscope Front-End, Medical Ultrasound Beamforming, Cable TV and Set-Top Box Downconverters, Radar and Lidar Signal Acquisition, Automated Test Equipment Digitizers.
Software-Defined Radio IF Sampling
The ADC11C170CISQ/NOPB is well matched to software-defined radio (SDR) IF-sampling front-ends because its 1.1 GHz analog input bandwidth lets a single ADC undersample IF signals in the second or third Nyquist zone, replacing a traditional mixer-plus-baseband-ADC chain. At 170 MSPS conversion rate the part supports real digital channelization of cellular, Wi-Fi, and broadcast IFs. Power consumption and CMOS-friendly 1.8V outputs ease pairing with low-cost FPGAs (e.g., Lattice LC4032V-25TN48C as shown in the TI SNAU088 evaluation board). Place the converter close to the front-end LNA and drive it from a differential amplifier such as the LMH6554 with matched baluns to preserve SNR.
推荐
Digital Oscilloscope Front-End
Within a 4 GHz-class digital-storage oscilloscope input stage, the ADC11C170CISQ/NOPB can be clocked at 170 MSPS to digitize the IF output of the attenuator/digitizer path in equivalent-time sampling or as part of a multi-ADC interleaved architecture. Its 1.1 GHz analog bandwidth allows direct sampling of repetitive waveforms up to ~430 MHz in real-time mode, while parallel-CMOS outputs feed downstream FPGA memory (a typical companion pairing is XC7A100T-1FTG256C for the capture buffer). The exposed-pad WQFN package keeps the analog front end thermally stable, preserving INL/DNL over warm-up.
推荐
Medical Ultrasound Beamforming
In portable ultrasound receivers, each channel needs a mid-resolution high-speed ADC to digitize the post-TGC analog signal at IF. The ADC11C170CISQ/NOPB's 11-bit resolution and 170 MSPS rate deliver roughly 66 dB dynamic range, sufficient for diagnostic imaging channels while keeping per-channel power below budget. The CMOS output bus feeds channel multiplexing directly into a Spartan-6 or Artix-7 FPGA (XC6SLX9-2TQG144I is a Site MPN candidate for the back-end beamformer). The industrial -40C to +85C range covers clinical and field-deployable units without derating.
推荐
Cable TV and Set-Top Box Downconverters
Digital cable head-ends and high-end set-top boxes need wideband IF sampling of downstream QAM carriers. The 1.1 GHz analog input bandwidth of the ADC11C170CISQ/NOPB lets the part directly digitize 44 MHz, 100 MHz, or up to ~860 MHz DOCSIS IFs, eliminating an analog SAW filter and dedicated tuner IC. The 11-bit dynamic range comfortably resolves 256-QAM constellations. CMOS outputs glue directly to a downstream demodulator FPGA such as XC6SLX16-2FTG256C (Site MPN candidate) running DOCSIS MAC/PHY stacks.
推荐
Radar and Lidar Signal Acquisition
Pulsed automotive and industrial radar/lidar receivers require ADC front-ends that can directly digitize intermediate frequencies above 50 MHz without an analog mixer. The ADC11C170CISQ/NOPB's 1.1 GHz bandwidth and 170 MSPS rate comfortably sample IF stages of FMCW radar and pulsed-lidar front-ends, returning I/Q digital streams to the host DSP (e.g., TI C6000 series). The 48-WQFN package keeps the analog front end compact, an important consideration when arrays of these receivers are tiled on a single PCB.
推荐
Automated Test Equipment Digitizers
In production ATE digitizer cards, the ADC11C170CISQ/NOPB delivers 170 MSPS sampling with 11-bit resolution - well-matched to stimulus-response test of mixed-signal ICs up to a few hundred MHz. The part's CMOS outputs feed directly into downstream DUT-pattern comparison logic implemented in an XC7A100T-1FTG256C or similar Artix-7 FPGA (Site MPN candidate). Wide operating temperature (-40C to +85C) supports both chamber-based and benchtop ATE without derating. The exposed-pad WQFN allows efficient PCB thermal management at continuous 170 MSPS operation.

设计说明
Estimated: at 170 MSPS with a 100 MHz analog input, a 1 ps RMS clock jitter will degrade SNR by roughly 10 * log10 (2 * pi * 100e6 * 1e-12) ~ 56 dB, theoretically the SNR floor. To preserve > 55 dB dynamic range the clock source jitter must remain below 200 fs; use a low-jitter clock generator and keep CLK+/CLK- routing as a 100 ohm differential pair with length matching. Place the clock generator as close to the ADC as possible.
Estimated: the 48-WQFN exposed thermal pad must be soldered to a continuous PCB ground plane covering at least 1 square inch of copper. Use a via array with 0.3 mm thermal vias at 1 mm pitch in the pad area. Decouple AVDD and DRVDD with 0.1 uF X7R ceramic capacitors placed within 2 mm of each supply pin, with a bulk 10 uF tantalum at each supply rail entry.
Estimated: the ADC11C170's CMOS outputs are 1.8 V - connecting them directly to a 3.3 V FPGA I/O bank will not work. Use the Lattice LC4032V-25TN48C PLD as referenced in TI SNAU088 to translate the ADC's 1.8 V CMOS outputs to 3.3 V CMOS for interfacing with legacy 3.3 V WaveVision capture hardware. When using a newer 1.8 V-tolerant FPGA such as XC7A35T-1FTG256C (Site MPN candidate), the PLD is unnecessary and outputs can be wired directly.
Estimated: total power consumption at full 170 MSPS operation is typically ~400 mW. Provide separate analog and digital supplies (AVDD ~ 1.8 V, DRVDD ~ 1.8 V) and star-ground them at the ADC reference. Avoid sharing DRVDD return paths with high-current digital outputs - separate analog and digital ground planes stitched together only under the exposed pad.
