ADS5413-11IPHPG4 概述
An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples continuous analog voltages and converts them into discrete digital codes for downstream DSP, FPGA, or microcontroller processing. Within the signal-chain taxonomy, the ADS5413-11 belongs to the high-speed pipelined ADC family, which sits between successive-approximation-register (SAR) ADCs (low speed, high accuracy) and flash ADCs (highest speed, lowest resolution). Pipeline ADCs use multiple cascaded low-resolution stages to balance speed, resolution, and power, making them the dominant choice for communications, radar, IF-sampling, and wideband instrumentation.
Key features include 11-bit resolution (the parent ADS5413 family is 12-bit; the -11 variant truncates to 11 bits), a 65 MSPS maximum sample rate, a 1.0 GHz analog input bandwidth (per parent family), on-chip sample-and-hold, duty-cycle adjust circuit for clock conditioning, two's-complement offset-binary output format, and selectable internal or external reference. The HTQFP-48 PowerPad package provides a low thermal resistance path (~28 C/W with proper PowerPad soldering), enabling continuous 65 MSPS operation without external heatsinking.
The ADS5413-11 uses a multi-stage switched-capacitor pipeline architecture with digital error correction, achieving 64.5 dBFS SNR and ~80 dBcSF spurious-free dynamic range at baseband. The wide 1 GHz analog front-end permits under-sampling of IF signals up to several hundred MHz, eliminating an entire downconversion stage in transceiver designs.
Typical applications include cellular base-station IF digitizers, cable-headend downstream receivers, radar and electronic-warfare intermediate-frequency sampling, medical imaging front-ends, and high-speed test-and-measurement digitizers. The 65 MSPS / 11-bit combination strikes a balance between ENOB and cost for wideband IF chains.
When designing with this device, place the differential input coupling capacitors within 5 mm of the INP/INN pins and route the CLK input as a 50 ohm matched differential pair to preserve SFDR. The PowerPad must be soldered to a continuous ground plane for thermal dissipation and AC grounding. Use the duty-cycle adjust feature to compensate for non-50% clock duty cycles introduced by long clock traces.

典型应用
ADS5413-11IPHPG4 适用于 6 应用s: Cellular Base-Station IF Digitiser, Cable Headend Downstream Receiver, Radar / Electronic Warfare IF Sampling, Medical Imaging Front-End, High-Speed Test and Measurement Digitiser, Software-Defined Radio (SDR) Wideband IF.
Cellular Base-Station IF Digitiser
The ADS5413-11IPHPG4 fits cellular base-station IF sampling because its 1.0 GHz analog input bandwidth permits direct under-sampling of IF signals in the 70-250 MHz range, eliminating a complete analog down-conversion mixer stage. Its 65 MSPS sample rate and 64.5 dBFS SNR provide sufficient dynamic range for UMTS / LTE / 5G NR downlink chains when paired with a 3.3 V LNA and SAW filter. Placed on a 4-layer FR-4 board with the exposed PowerPad soldered to a continuous ground pour, it dissipates 400 mW continuously without external heatsink. The on-chip duty-cycle adjust circuit compensates for non-50% clock duty cycle introduced by long FPGA-to-ADC clock traces, a common challenge in 6U rack-mounted radio units. Recommend pairing with TI ADC3x family clock jitter cleaners for sub-100 fs RMS jitter.
推荐
Cable Headend Downstream Receiver
In cable headend downstream receivers, the ADS5413-11IPHPG4 digitises the 50-870 MHz downstream band with one ADC per QAM channel segment, replacing multi-stage analog tuners. The wide 1.0 GHz input bandwidth and 2 Vpp differential full-scale range accommodate the high peak-to-average ratio of aggregated DOCSIS 3.1 OFDM carriers, while the 65 MSPS sample rate supports symbol rates up to ~52 MBaud. The two's-complement output format integrates directly with downstream FPGA-based demodulators. The HTQFP-48 PowerPad package maintains junction temperature below 100 C at 400 mW with a 1 square-inch top-side copper pour. Recommend pairing with TI LMH6517 variable-gain amplifier for input range control.
推荐
Radar / Electronic Warfare IF Sampling
The ADS5413-11IPHPG4 suits radar and electronic-warfare intermediate-frequency sampling where its 11-bit resolution is more than adequate after front-end filtering, and its 1.0 GHz input bandwidth allows direct under-sampling of L-band (1-2 GHz) IF signals from a radar receiver's first mixer. The pipelined architecture delivers consistent ENOB across input frequencies up to 300 MHz, and the 400 mW power budget fits easily into the thermal envelope of airborne EW pods. The on-chip sample-and-hold holds aperture delay under 200 ps, preserving phase coherence across multiple sampled pulses. PowerPad soldering is critical: a 4-layer FR-4 stack-up with stitched ground vias under the package keeps theta_JA near 28 C/W. Recommend pairing with TI ADC08D1500 for higher-resolution channels.
推荐
Medical Imaging Front-End
In medical imaging front-ends such as ultrasound beamformers and MRI receivers, the ADS5413-11IPHPG4 samples the IF output of the first downconversion stage at up to 65 MSPS, providing 11-bit dynamic range sufficient for tissue-echo amplitude measurement. The two's complement output interfaces directly with low-cost FPGAs that perform envelope detection and beam steering. The 3.3 V analog and 1.8 V digital supplies simplify power-tree design in battery-portable cart-based ultrasound systems. Power dissipation of 400 mW across 48 channels fits within the thermal budget of a chassis-mounted fan-cooled enclosure. The device's pin-compatible 12-bit sibling (ADS5413IPHPG4) provides a simple upgrade for higher-end imaging modalities without board rework.
推荐
High-Speed Test and Measurement Digitiser
The ADS5413-11IPHPG4 fits cost-sensitive test and measurement digitiser cards that need 11-bit dynamic range at sample rates up to 65 MSPS, such as benchtop oscilloscope front-ends and modular data-acquisition cards. Its 1.0 GHz analog bandwidth allows direct sampling of repetitive waveforms well above the Nyquist limit, enabling equivalent-time sampling modes. The 400 mW power dissipation is acceptable in rack-mounted instruments with forced-air cooling. The PowerPad package provides good thermal performance in compact card cages. Pin compatibility with the 12-bit ADS5413 family offers an easy upgrade path for higher-resolution variants without PCB redesign. Recommend pairing with TI DAC38J84 for stimulus generation channels.
推荐
Software-Defined Radio (SDR) Wideband IF
In software-defined radio platforms, the ADS5413-11IPHPG4 digitises the wideband IF output of the analog front-end tuner at 65 MSPS, providing a sample stream to an FPGA or DSP that performs channelisation, demodulation, and decoding in software. Its 11-bit resolution is adequate for many consumer-grade and amateur-radio applications, while the wide 1.0 GHz input bandwidth permits direct sampling of intermediate frequencies up to ~300 MHz without aliasing. The 3.3 V analog supply and 1.8-3.3 V digital I/O supply simplify integration with modern low-power FPGAs such as Xilinx Spartan-6 / Artix-7 families. Recommend pairing with TI AFE5808A for ultrasound-style analogue front-end integration.

关键差异点
- 1.0 GHz analog input bandwidth permits direct under-sampling of high-IF signals up to several hundred MHz （对比 ADS5413-11IPHP (same part, non-G4 reel))
- On-chip duty-cycle stabiliser compensates for non-50% clock duty cycle （对比 Generic pipelined ADCs in same package)

设计说明
Estimated: With 400 mW power dissipation and a 4-layer FR-4 PCB that includes a 1 square-inch top-side ground copper pour stitched with the PowerPad thermal pad, junction-to-ambient thermal resistance (theta_JA) is approximately 28 C/W, yielding a 11 C junction rise above 25 C ambient. This provides adequate margin below the 125 C absolute maximum. Without a continuous PowerPad solder connection, theta_JA can rise above 60 C/W, pushing the junction above the absolute maximum during sustained 65 MSPS operation. Source: TI ADS5413 datasheet PowerPad thermal guidelines.
Place the differential analog input coupling capacitors within 5 mm of the INP and INN pins to preserve SFDR. Route INP and INN as a 100 ohm differential microstrip pair on the top layer over a continuous ground plane. The differential clock pair (CLKP / CLKN) should follow the same routing discipline with 50 ohm single-ended impedance and matched trace lengths within 1 mm to preserve aperture-delay matching. The on-chip duty-cycle adjust circuit compensates for non-50% duty cycle introduced by long clock traces. Source: TI ADS5413 datasheet Layout section.
Estimated: At maximum sample rate of 65 MSPS with 3.3 V analog supply, the device draws approximately 121 mA from AVDD (400 mW / 3.3 V). Place 0.1 uF X7R ceramic decoupling capacitors within 5 mm of every AVDD pin, plus a 10 uF bulk tantalum or polymer capacitor on the analog supply trace. Separate analog (AVDD / AGND) and digital (DRVDD / DRGND) supplies with ferrite beads to prevent digital switching noise from coupling into the analog front-end. Source: TI ADS5413 datasheet Power Supply Recommendations section.
The SENSE pin selects internal (tie to AGND) or external (tie to AVDD) reference mode. Leaving SENSE floating is undefined behaviour and may cause the reference voltage to drift, leading to gain errors. The DCS (duty-cycle stabiliser) pin must be tied high for stable operation across clock duty cycle variation; tying it low disables the stabiliser and may introduce harmonic spurs. Reference bypass capacitors on REFT and REFB must be low-ESR X7R ceramics of 0.1 uF; using larger bulk capacitors without the local 0.1 uF may cause reference instability.
