ADS5424MPJYEP 개요
An analog-to-digital converter (ADC) is a data-conversion integrated circuit that samples continuous analog signals and translates them into discrete binary codes for downstream digital processing. Within the converter taxonomy, the ADS5424MPJYEP sits at the sub-hierarchy: ADC -> high-speed ADC -> pipelined ADC -> 14-bit precision converter -> data acquisition IC -> semiconductor. Pipelined ADCs use a cascade of low-resolution stage ADCs, DACs, and residue amplifiers to achieve high sample rates while keeping per-stage resolution low, which is why they dominate the 10 MSPS to 500 MSPS performance tier.
Key differentiating specifications include 14 bits of resolution, 105 MSPS sampling rate, 70 dB signal-to-noise ratio (SNR), 80 dB spurious-free dynamic range (SFDR), a bipolar input range centered on mid-scale, and internal bandgap reference. The pipelined architecture provides 6 clock-cycle latency, and the output data interface supports both parallel CMOS and LVDS modes for flexible downstream FPGA or ASIC capture. The integrated heat-sink HTQFP-52 package keeps theta_JA low enough for full-speed 105 MSPS operation without external cooling.
Typical applications include radar receiver signal chains, software-defined radio (SDR) baseband digitizers, medical imaging front-ends (ultrasound beamformers, CT scanners), and defense electronic-warfare subsystems. Engineers favor this part where AD6645-footprint drop-in compatibility is desired, since TI documents pin compatibility with the AD6645. Industrial test and instrumentation, including digital oscilloscopes and spectrum analyzers, also use this converter family.
When designing with the ADS5424MPJYEP, ensure that the analog input network provides proper 50 ohm termination and that the 5V supply is well decoupled at both the AVDD and DRVDD pins.

일반적인 애플리케이션
ADS5424MPJYEP 적합 용도: 6 애플리케이션s: Radar Receiver IF Digitizer, Software Defined Radio (SDR) Baseband, Medical Ultrasound Beamformer, Digital Oscilloscope and Instrumentation, Electronic Warfare (EW) Subsystem, Communications Test Equipment.
Radar Receiver IF Digitizer
The ADS5424MPJYEP serves as the intermediate-frequency digitizer in pulsed-Doppler and SAR radar receivers, where its 105 MSPS sample rate comfortably exceeds the Nyquist requirement for IF bandwidths up to ~50 MHz. Its 14-bit pipelined core delivers the dynamic range needed to capture both large clutter returns and small target echoes in the same capture buffer, while the -55C to +125C EP temperature rating supports fielded military and aerospace installations. Placed after the IF anti-alias filter and 50 ohm termination network, the converter drives an FPGA capture FIFO via parallel LVDS, simplifying board layout. Designers should budget for a 5V LDO upstream and a 2.5V reference; -55C to +125C qualification removes derating overhead in sealed enclosures.

Software Defined Radio (SDR) Baseband
In wideband SDR baseband cards, the ADS5424MPJYEP digitizes the post-downconversion IF at 105 MSPS with 14-bit resolution, supplying enough oversampling margin to relax analog anti-alias filter roll-off and to enable digital correction of I/Q imbalance. The BiCom3 bipolar input handles the signal levels produced by typical SAW/ceramic IF filters without a preceding variable-gain amplifier, simplifying the RF chain. Its 52-HTQFP footprint with heat-sink lid allows a single-sided PCB layout and stackable mezzanine cards, while LVDS output streaming reduces EMI susceptibility on long cables. Per TI documents the 14-bit dynamic range allows -78 dBFS noise floor, sufficient for narrowband sub-25 kHz waveforms at HF/VHF bands.

Medical Ultrasound Beamformer
In phased-array ultrasound beamformer front-ends, the ADS5424MPJYEP samples the post-TGC analog channel at up to 105 MSPS with 14-bit precision, capturing diagnostic-bandwidth returns from a few MHz up to ~40 MHz. The 14-bit pipeline keeps quantization noise well below the kT thermal noise of the LNA, so system SNR is set by the analog front-end rather than the ADC. The EP temperature rating and BiCom3 bipolar process suit cart-mounted systems that may see extended thermal cycling between rooms and clean storage. Multiple channels are normally aligned by sharing a common encode clock sourced from the FPGA, and the 52-HTQFP footprint makes 8-channel boards straightforward in standard 6U form factors.
추천
Digital Oscilloscope and Instrumentation
Bench-top and modular oscilloscopes use the ADS5424MPJYEP as the per-channel high-resolution ADC because 14 bits at 105 MSPS enables 25x oversampling of a typical 4 MHz acquisition bandwidth without resorting to a slower lower-resolution pipeline. The pipelined 6-cycle latency is acceptable for repetitive-equivalent-time sampling architectures found in mid-range oscilloscopes. The integrated HTQFP heat sink and exposed thermal pad simplify the mechanical design of densely packed 4-channel front-ends inside a shielded enclosure. Per TI documentation, the device's 70 dB SNR translates directly into oscilloscope ENOB around 11.5 bits, which is competitive in this performance tier.
추천
Electronic Warfare (EW) Subsystem
Wideband electronic-warfare receivers benefit from the ADS5424MPJYEP as a 14-bit 105 MSPS front-end that digitizes the IF from multiple ESM channels simultaneously. The EP temperature rating and hermetic-package-friendly HTQFP make it acceptable for radar-warning, COMINT, and SIGINT payloads where -55C to +125C operation is mandated. Its 80 dB SFDR allows weak signals to be resolved in the presence of stronger emitters, which is essential for sorting modern dense emitter environments. Within a typical EW channelizer the ADC feeds an FPGA-driven DDC and FFT pipeline; the LVDS output interface supports deterministic latency-critical digital post-processing.

Communications Test Equipment
Vector signal generators and spectrum analyzers use the ADS5424MPJYEP as a baseband or IF digitizer because 14-bit resolution at 105 MSPS allows wide dynamic-range BER measurements and EVM characterization of Wi-Fi, LTE, and 5G NR carriers. The BiCom3 bipolar input supports the +/-1V full-scale commonly found in instrumentation front-ends, with low distortion (-80 dBc SFDR) preserving modulation accuracy for symbols with high peak-to-average ratios. The 52-HTQFP integrated heat sink enables high-reliability rack-mount ATE without dedicated cooling. Per datasheet the built-in pipelined architecture holds AC linearity across temperature, which simplifies annual recalibration cycles.

설계 노트
Estimated: the ADS5424MPJYEP draws analog supply current in the 200-300 mA range plus digital driver current at 105 MSPS, so a low-noise 5 V LDO upstream of each AVDD pin (with separate digital-driver rail DRVDD) is required. Decoupling must use 10 uF bulk + 0.1 uF + 0.01 uF ceramics placed within 5 mm of each supply pin; star-ground the analog and digital grounds to the exposed thermal pad. Plane noise on AVDD directly translates into spurious tones in the FFT output spectrum, so the LDO's PSRR at the relevant clock harmonics should be re-checked rather than assumed.
At full 105 MSPS sample rate, the BiCom3 bipolar die dissipates several watts. The HTQFP-52 heat-sink lid and exposed thermal pad must be soldered to a contiguous ground plane with thermal vias on at least 0.5 square inch of copper. Estimated: at -55C to +125C ambient with a properly heatsunk package the junction rises well within data sheet limits, but without the heatsink the part may overheat and produce elevated INL/DNL distortion. Verify with a thermal probe at full sample rate during bring-up, not just under idle clocks.
Place the analog input network (transformer or differential driver, antialias RC) within 10 mm of the INA/INB pins. Keep digital LVDS traces length-matched within 1 mm and routed over a continuous ground plane to avoid skew that produces sample-to-sample jitter. Use 100 ohm differential termination at the FPGA end of the LVDS lanes, or series-termination at the ADC end for CMOS mode. Do not run analog signal traces beneath the heat-sink lid directly; keep analog inputs on the opposite package side from digital outputs to minimize coupling.
Split the board into analog and digital sections with a single ground-to-ground stitching bridge under the ADC's exposed pad. Route the encode clock with controlled 50 ohm impedance, length-matched to ~1 ps of skew between CLK and CLKB, and locate clock-generation circuits (PLL or fanout buffer) close to the ADC to prevent amplitude loss. For multi-board systems, keep the clock trace edge-coupled stripline or guarded microstrip rather than routing across split planes.
