ADC1003S030TS/C1 概要
What is a video ADC? A video analog-to-digital converter (video ADC) is a specialized high-speed ADC optimized for digitizing analog video signals in real time. The 10-bit resolution class is the broadcast industry standard (ITU-R BT.601 / SMPTE 259M) because it provides 1024 quantization levels - enough dynamic range to encode luma and chroma information with visually lossless fidelity after gamma correction. Compared to general-purpose ADCs, video ADCs include internal clamping, gain stages, and often an integrated reference, reducing external component count for video capture cards, broadcast equipment, and professional camera systems.
The ADC1003S030 family uses a pipelined flash architecture with a 2.5 V p-p full-scale input range. The integrated voltage regulator lets the digital and analog sections share a single 3.3 V rail, simplifying PCB layout. A 30 MSPS sampling rate is sufficient for SDTV (480i/576i) and CIF-resolution digital video, and the same footprint scales to 40 MHz (ADC1003S040) and 50 MHz (ADC1003S050) members for higher-bandwidth video formats.
Typical applications include professional video digitizers, broadcast equipment, surveillance DVRs, medical imaging front-ends, and high-speed data acquisition cards. Pin compatibility with the ADC1003S040 and ADC1003S050 means designers can drop in a higher-speed part if more bandwidth is needed without re-laying the board.
When designing with this ADC, provide a low-impedance analog input path with 75-ohm termination (the standard for video), use a stable low-jitter sampling clock, and bypass the on-chip regulator with a 100 nF plus 10 uF capacitor pair on the analog supply pin.

主な用途
ADC1003S030TS/C1 の用途: 6 件s: Professional Video Digitizer / Capture Card, Surveillance DVR / CCTV Front-End, Broadcast Studio Equipment, Medical Imaging Front-End (Ultrasound/Endoscope), Industrial High-Speed Data Acquisition, Set-Top Box / Digital TV Downconverter.
Professional Video Digitizer / Capture Card
The ADC1003S030TS/C1:1's 10-bit resolution matches the ITU-R BT.601 standard for SDTV (480i/576i) capture, while its 30 MSPS sampling rate easily oversamples NTSC/PAL baseband (4x for NTSC's 4.2 MHz bandwidth, 3x for PAL's 5 MHz). Place the ADC after a 75-ohm-terminated input amplifier and sync stripper; the on-chip regulator eliminates a separate analog LDO. Use a low-jitter 30 MHz clock from a dedicated PLL or crystal oscillator to meet SNR targets above 56 dB.
おすすめ
Surveillance DVR / CCTV Front-End
The ADC1003S030TS/C1:1 is ideal for multi-channel CCTV DVR front-ends digitizing composite video. The 10-bit dynamic range captures 256 luminance levels per ITU-R BT.601, sufficient for surveillance footage after compression. Its 95 mW power consumption allows high-density multi-channel boards. The integrated voltage regulator simplifies the 3.3 V power tree, and the commercial 0 C to +70 C rating covers indoor DVR chassis. Drive the analog input via a 75-ohm back-terminated amplifier per CCTV best practice.
おすすめ
Broadcast Studio Equipment
The ADC1003S030TS/C1:1 supports SD-SDI studio equipment at 270 Mbps when the 30 MSPS rate oversamples the 10-bit scrambled-NRZ data. Its pipelined architecture with integrated regulator suits studio chassis where thermal stability matters. Engineers pair it with downstream SDI framer chips. The 28-SSOP package is easy to rework during prototype iteration, and the 3.3 V single-supply operation simplifies mixed-signal PCB partitioning in studio router/DA equipment.
おすすめ
Medical Imaging Front-End (Ultrasound/Endoscope)
The ADC1003S030TS/C1:1's 10-bit resolution and 30 MSPS rate are appropriate for medical imaging modalities like mid-tier ultrasound signal chains and endoscope camera digitizers. The integrated regulator reduces PCB footprint for compact probe heads. For lower-power medical battery designs, the 95 mW dissipation is acceptable. Use medical-grade isolation barriers downstream. The 0 C to +70 C commercial range covers clinical environments; for OR-grade equipment, validate with the IEC 60601-1 system-level standard at the OEM level.
おすすめ
Industrial High-Speed Data Acquisition
The ADC1003S030TS/C1:1 fits 16-bit-equivalent industrial DAQ cards where 10-bit resolution is sufficient for vibration, acoustic, or process-control sensing. The 30 MSPS rate handles multi-MHz transducer signals. Its pipelined architecture delivers low aperture jitter for time-domain accuracy. The on-chip voltage regulator reduces BOM cost in compact industrial modules. The commercial 0 C to +70 C range is sufficient for indoor control cabinets; pair with sealed enclosures for harsher industrial environments.
おすすめ
Set-Top Box / Digital TV Downconverter
The ADC1003S030TS/C1:1 digitizes IF outputs in legacy set-top box tuners at 30 MSPS with 10-bit accuracy, sufficient for QAM/ATSC demodulation after digital downconversion in the downstream demodulator IC. Its single 3.3 V supply aligns with set-top box power trees, and the integrated regulator simplifies the mixed-signal PCB. The SSOP-28 footprint is friendly to compact set-top box main boards where board area is constrained and the 5.3 mm body is straightforward to assemble by high-volume SMT lines.

設計ノート
Place the analog input amplifier (75-ohm terminated) within 5 mm of the AIN pin to minimize trace capacitance. Use a ground plane on layer 2 with a cutout under the AIN input trace; route the analog and digital sections on separate islands of the ground plane joined at the AGND/DGND pins. Keep the 30 MHz clock trace short and guarded with ground on both sides to limit coupling into the analog input.
Bypass AVDD with a 100 nF X7R ceramic in parallel with a 10 uF tantalum placed within 2 mm of the pin. The on-chip voltage regulator needs this bulk capacitance to maintain regulation under dynamic load (LSB transitions). Decouple DVDD and DRVDD separately, with their own 100 nF/10 uF pairs, to prevent digital switching noise from coupling into the analog section.
Use a low-jitter clock source (RMS jitter < 5 ps) to maximize SNR. The ADC's aperture jitter specification sets the achievable SNR at high input frequencies: SNR = 20*log10(1/(2*pi*f_in*T_jitter)). For 15 MHz video input and 5 ps jitter, SNR ceiling is approximately 56 dB - within 1 dB of the 10-bit theoretical maximum. Avoid using FPGA-generated clocks for the sampling clock; use a dedicated clock generator or crystal oscillator.
Do not leave the OE (output enable, pin 22) floating - tie it to logic high for normal operation. Leave STBY and PWRDN low (disabled) during normal operation. The CLAMP pin (pin 2) requires an external capacitor to AGND to set the DC restore time constant; consult the datasheet for the recommended value (typically 47 nF to 100 nF). Driving a 2.5 V p-p input beyond the datasheet's absolute maximum (3.3 V) may permanently damage the input ESD structure.
