ADC14DS105CISQE/NOPB Übersicht
A pipelined ADC is a high-speed analog-to-digital converter architecture that uses multiple low-resolution stages in series to achieve high overall sample rates with moderate resolution; it sits within the broader analog-to-digital converter category under data converters and mixed-signal ICs. Dual-channel simultaneous-sampling converters such as the ADC14DS105 are widely used where two correlated signals must be captured at the same instant, such as I/Q baseband channels in communications, the X and Y axes of a complex sensor, or the analog front ends of multi-antenna systems.
Key features of this part include 14-bit resolution, 105 MSPS sampling rate per channel, serialized LVDS digital outputs, a low-voltage differential signaling interface, an internal reference and sample-and-hold stage, and support for an external clock input. The 60-WQFN exposed-pad package offers a thermal pad that reduces junction-to-ambient thermal resistance, enabling reliable operation across the -40 to +85 C industrial temperature range. The part accepts a 3.3 V nominal supply.
The device uses CMOS process technology with a pipelined architecture followed by digital post-processing that reserializes the converted data onto LVDS pairs. This minimizes the number of digital traces required to bring the data into an FPGA or ASIC, while preserving the 105 MSPS throughput and 14-bit dynamic range. The integrated serializer also reduces FPGA pin-count and routing congestion in space-constrained baseband boards.
Typical applications include communications baseband I/Q digitization, multi-channel data acquisition in test and measurement, dual-axis inertial sensing and instrument front-ends, and medical imaging signal chains. In each of these scenarios the simultaneous capture of two correlated signals at 105 MSPS is critical to preserving phase or timing relationships between channels.
When designing in this ADC, the LVDS serializer requires an LVDS-compatible receiver in the downstream FPGA and a stable low-jitter clock source; ground-bounce and supply-noise directly degrade SNR, so decoupling and PCB stackup should follow the TI reference layout. When higher sampling rates are required, the related ADC14DS080/095 family members allow designers to trade speed against power within the same footprint.

Typische Anwendungen
ADC14DS105CISQE/NOPB ist geeignet für 6 Anwendungs: Communications Baseband I/Q Digitization, Dual-Channel Data Acquisition Systems, Medical Imaging Signal Chain, Radar and Pulse-Doppler Front End, Industrial Process Control Digitizers, Software-Defined Radio Multi-Antenna Receiver.
Communications Baseband I/Q Digitization
The ADC14DS105CISQE/NOPB's simultaneous dual-channel 105 MSPS sampling makes it a clean fit for I/Q digitizers in wireless baseband receivers where two correlated analog paths must be captured at the same instant. Its 14-bit dynamic range preserves the signal-to-noise ratio needed for demodulation of QAM and OFDM waveforms, while the serialized LVDS output pairs shrink board traces from dozens of parallel lines to a handful of differential pairs, simplifying the PCB stack-up between ADC and baseband FPGA. Designers typically place the part downstream of the quadrature mixer with matched anti-alias filters on each input; the 60-WQFN exposed pad reduces thermal resistance so the part sustains 105 MSPS operation without derating. Compared with a parallel-output ADC of similar rate, this device cuts FPGA pin count materially without sacrificing dynamic range.

Dual-Channel Data Acquisition Systems
In test-and-measurement digitizers where two correlated analog signals must be captured at 105 MSPS, the ADC14DS105CISQE/NOPB delivers two simultaneous-sampling 14-bit channels in a single 60-WQFN package. The pipelined architecture settles in a few clock cycles so a triggered acquisition yields valid samples within microseconds, while the LVDS serializer keeps the FPGA interface compact - typically one LVDS clock pair and one LVDS data pair per channel. Engineers pair it with a low-jitter clock oscillator and matched input RC networks for anti-aliasing, and the exposed thermal pad ensures full industrial-temperature operation. Compared with two discrete ADCs requiring matched routing, this dual device saves board area and reduces channel-to-channel skew.

Medical Imaging Signal Chain
For ultrasound beamformers, RF-signal digitizers, and other medical imaging front-ends, the ADC14DS105CISQE/NOPB provides dual 14-bit channels at 105 MSPS - enough to capture baseband or pre-beamformed RF signals with the dynamic range needed for diagnostic-quality images. The CMOS pipeline architecture keeps power consumption low while maintaining wide spurious-free dynamic range, important for distinguishing tissue echoes from noise. The 60-WQFN exposed pad handles the continuous conversion duty cycle across -40 to +85 C, and the serialized LVDS output reduces EMI in sensitive analog environments. Designers typically pair the ADC with low-noise LDO regulators (such as TPS7A47xx family) on the analog supply rail and run the deserialization in an FPGA beamformer.
Empfohlen
Radar and Pulse-Doppler Front End
Pulsed and FMCW radar systems need simultaneous capture of I and Q baseband signals with high dynamic range; the ADC14DS105CISQE/NOPB provides dual 14-bit channels at 105 MSPS in a 60-WQFN package that fits the dense RF-to-baseband transition region. Its pipelined CMOS architecture settles quickly so successive pulses can be digitized without aliasing, and the serialized LVDS interface isolates the ADC's high-frequency clocks from the FPGA's general routing. The exposed pad draws heat away during continuous 105 MSPS operation, allowing the part to run within industrial temperature margins on the radar board. Compared with a separate ADC for each channel, this dual part reduces channel-to-channel gain and timing mismatch.

Industrial Process Control Digitizers
In programmable logic controllers, vibration monitors, and other factory-automation digitizers, the ADC14DS105CISQE/NOPB captures two high-speed sensor channels at 14-bit resolution and 105 MSPS - useful for vibration analysis, motor-drive current feedback, and precision encoder signals. Its -40 to +85 C industrial temperature range and 60-WQFN exposed-pad package survive factory-floor thermal stress, while the LVDS serializer keeps emissions low in noisy industrial enclosures. Engineers commonly pair it with isolated front-end signal conditioning and an FPGA or DSP for FFT analysis. Compared with single-channel ADCs the dual-channel part reduces PCB area and improves the timing alignment between paired process signals.
Empfohlen
Software-Defined Radio Multi-Antenna Receiver
Multi-antenna SDR front-ends require simultaneous capture of multiple correlated analog channels at the same sample instant; the ADC14DS105CISQE/NOPB delivers dual 14-bit channels at 105 MSPS with the timing alignment needed for beamforming and MIMO decoding. The serialized LVDS interface allows the ADC to sit close to the antenna RF front-end while the FPGA is further down the board, keeping analog signal paths short. The 60-WQFN exposed pad sustains junction temperature under continuous SDR operation, and the pipelined architecture provides the SFDR required to distinguish multiple carriers. Designers benefit from the part's LVDS protocol, which lets them chain multiple dual ADCs into a synchronized array using a common clock.

Designhinweise
Estimated: For the ADC14DS105CISQE/NOPB, keep analog input traces matched to within 1 mm of each other and surround them with a continuous ground-and-supply-return fence to minimize inter-channel skew at 105 MSPS. The LVDS serialized outputs at up to 105 MSPS toggle at LVDS rates - route each LVDS pair as tightly matched differential length, and provide a 100 ohm differential termination at the receiver. The exposed thermal pad must be soldered to a continuous ground plane with thermal vias into the inner ground layers so the part can sustain 105 MSPS full-scale toggling without exceeding the -40 to +85 C industrial temperature budget.
Estimated: Decoupling per the TI reference layout - place one 10 uF ceramic bulk capacitor plus one 0.1 uF high-frequency ceramic capacitor directly at each analog supply pin, with short return paths to the ground paddle. Separating analog and digital supply planes with a ferrite bead isolates the LVDS serializer switching current from the analog front-end. Power-supply ripple in excess of a few millivolts will degrade SNR at 14-bit resolution, especially at high input frequencies, so a low-noise LDO (similar to TI TPS7A47xx family) on the analog rail is recommended.
Estimated: A common mistake is driving the ADC14DS105CISQE/NOPB with a poor-quality clock; sample-to-sample jitter translates directly into aperture jitter, degrading SNR. Use a low-jitter crystal or clock oscillator (under 1 ps RMS) matched to the ADC clock input impedance. Another frequent pitfall is operating the device above 105 MSPS continuous - this causes thermal runaway because the CMOS pipeline draws proportionally to sample rate, so continuous duty-cycle operation must stay within the thermal envelope defined by the package and exposed pad.
