ADS5423MPJYEP 概要
What is a pipelined ADC? A pipelined analog-to-digital converter is a high-speed converter architecture that uses multiple low-resolution stages (commonly 1.5 bits per stage) operating concurrently on different samples to achieve tens to hundreds of MSPS while consuming modest power. The architecture sits in the hierarchy ADC > high-speed ADC > pipelined ADC > data-conversion IC > semiconductor; pipelined ADCs dominate mid-to-high-speed IF sampling in communications, imaging, and defense systems where 80-200 MSPS conversion is required.
Key specifications of the ADS5423MPJYEP include 14-bit resolution, 80 MSPS maximum sampling rate, 70 dB SNR typical at 10 MHz input, SFDR of 80 dB, and 5 V analog / 3.3 V digital supply operation. The integrated input buffer, internal reference, and programmable full-scale range simplify board design, while LVCMOS/CMOS-compatible outputs interface directly with ASICs or DSP glue logic. The 52-QFP package is surface-mount friendly and offers a 10x10 mm footprint compatible with both industrial SMT lines and ruggedized defense assembly flows.
At the architecture level, the device uses a multi-stage pipelined front-end followed by digital error correction, achieving excellent linearity (DNL/INL < 1 LSB typical) without requiring calibration. The internal reference reduces external component count, and the 3.3 V CMOS outputs avoid the need for level shifters into low-voltage FPGAs or DSPs.
Typical applications include radar and EW receivers, medical imaging front-ends, communications IF sampling, baseband I/Q digitization, and high-performance industrial instrumentation. The wide temperature grade allows direct use in outdoor or vehicle-mounted defense electronics. When designing with this ADC, follow the standard high-speed ADC layout practice: solid ground planes, decoupling within 5 mm of each supply pin, controlled-impedance analog inputs, and a noise-isolated analog/digital split to achieve datasheet SFDR performance.

主な用途
ADS5423MPJYEP の用途: 6 件s: Radar IF / Baseband Sampling, Medical Imaging Front-End (Ultrasound / MRI), Software Defined Radio (SDR) Wideband IF, Communications Baseband I/Q Digitization, Industrial Test & Measurement Instrumentation, Electronic Warfare (EW) Receiver Digitizers.
Radar IF / Baseband Sampling
The ADS5423MPJYEP fits radar IF/baseband sampling because its 14-bit resolution at 80 MSPS captures enough dynamic range to preserve narrowband pulse returns. The integrated input buffer isolates the ADC sampling-capacitor switching from the source so filter designers see a stable R_load rather than kickback transients, and 80 dB SFDR keeps spurious-free dynamic range sufficient for ground-based and airborne radar front-ends operating in dense RF environments. The defense-grade -55C to +125C temperature rating allows use at outdoor antenna arrays and unconditioned pod environments.
おすすめ
Medical Imaging Front-End (Ultrasound / MRI)
Medical ultrasound and MRI IF channels are well-served by the ADS5423MPJYEP at 80 MSPS sample rate, which provides the bandwidth needed to capture harmonic-rich broadband return echoes while the 14-bit dynamic range preserves tissue contrast. The integrated input buffer is critical here because ultrasound transducers present complex source impedances and benefit from a buffered ADC that does not load the receive chain. The 3.3 V CMOS outputs interface directly to legacy DSP engines used in FDA-cleared medical imaging platforms.
おすすめ
Software Defined Radio (SDR) Wideband IF
Wideband-IF SDR receivers are increasingly built on 80-100 MSPS ADCs to digitize 25+ MHz of bandwidth in a single anti-aliasing envelope. The ADS5423MPJYEP at 14-bit 80 MSPS hits the sweet spot for HF/VHF/UHF commercial SDR, ham-radio transceivers, and tactical SDR platforms; 70 dB SNR at 10 MHz is sufficient for AM/FM/SSB/CW demodulation chains while the input buffer eliminates the need for a costly driver amplifier. Pairing with a digital down-converter (DDC) FPGA provides the IQ baseband a low-cost SDR radio requires.
おすすめ
Communications Baseband I/Q Digitization
In wireless base-station receivers and satellite-comms terminals, the ADS5423MPJYEP digitizes baseband I/Q at sufficient rate to capture multi-carrier 3G/4G signals after the IF down-conversion. 80 MSPS easily covers 25 MHz of composite baseband bandwidth while 14-bit resolution preserves EVM at high-order QAM modulation. The CMOS outputs simplify FPGA glue logic and reduce EMI compared with LVDS interfaces, important for noise-sensitivity in dense base-station rack layouts.
おすすめ
Industrial Test & Measurement Instrumentation
High-end oscilloscopes, spectrum analyzers, and data-acquisition systems rely on 14-bit 80 MSPS converters like the ADS5423MPJYEP for their 50-ohm digitizing front-end. The integrated buffer eliminates one signal-conditioning stage, reducing channel cost and improving calibrated accuracy. Defense-grade temperature grading is useful for outdoor industrial deployments like cable-fault locators and power-grid monitoring hardware where ambient temperature swings exceed the industrial range.
おすすめ
Electronic Warfare (EW) Receiver Digitizers
Electronic warfare receivers operating in contested RF environments need wide bandwidth sampling at sufficient resolution to capture spread-spectrum threats. The ADS5423MPJYEP provides 14-bit resolution at 80 MSPS with an integrated buffer, allowing EW engineers to digitize 30+ MHz of intermediate frequency in a single integrated converter. The defense-grade screening and EP pedigree ensures per-die traceability mandated by military EW procurement specs (MIL-STD-810 environmental, MIL-PRF-38535 screening).

設計ノート
The ADS5423MPJYEP is a high-speed pipelined ADC and its analog performance is highly dependent on PCB layout. Split the analog and digital grounds on a single solid internal ground plane, with a single-point join (or stitched into one continuous plane) directly under the device's exposed pad. Place the 5 V AVDD bypass capacitors (typically 0.1 uF X7R plus 10 uF tantalum) within 5 mm of each AVDD pin, and connect the exposed thermal pad directly to AGND for ground and thermal relief.
Use controlled-impedance differential traces for the analog inputs (INP/INN); 100 ohm differential is typical. The clock input is also differential (CLK/CLKN). Keep traces short and use a guard ground around the analog input pair to prevent coupling from digital switch-back into the analog front-end. Maintain 50 ohm single-ended impedance for the digital CMOS outputs where they exit the analog section.
Datasheet values for SNR and SFDR are only achievable with proper decoupling, a clean low-jitter clock source (clock jitter < 0.5 ps rms), and the internal reference properly decoupled using REFT and REFB pins (recommended 0.1 uF plus 10 uF). DC-coupled operation requires the analog common-mode voltage be set correctly (around 2.4 V); AC-coupling users must reset the DC-bias with a bias-tee or external resistor network. Ensure the DRVDD supply is clean - 3.3 V CMOS switching noise can couple back into AVDD if shared inductively.
Clock-aperture jitter dictates achievable SNR: SNR_jitter-limited (dB) ~= 20*log10(1 / (2*pi*f_in*t_j)). For 70 dB SNR at 10 MHz input, the clock jitter budget is approximately 1 ps rms. Practical designs use an LVDS-grade clock generator (e.g. CDCLVC110 or LMK048x) ahead of the CLK/CLKN pins, terminated at the ADC clock pins with 100 ohm differential.
