TDA8763AM/3/C4 - 10-bit 30MSPS ADC, 28-SSOP | NXP
MPN: TDA8763AM/3/C4 ✗ Cuối đờiTDA8763AM/3/C4 Tóm tắt
An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous analog voltages into discrete digital codes, enabling microcontrollers, DSPs, and FPGAs to process real-world sensor and signal data. The hierarchy is: ADC -> data converter -> mixed-signal IC -> semiconductor. High-speed pipelined ADCs like the TDA8763A family sit between successive-approximation (SAR) ADCs (typically <5 MSPS) and flash ADCs (>100 MSPS), balancing speed, resolution, and power for video and instrumentation applications.
Key features include 10-bit resolution, 30 MSPS sampling rate, single-clock-cycle conversion latency, and a high signal-to-noise ratio suited for professional video digitisation. The /3 suffix denotes the 30 MHz speed grade, while /5 designates the 50 MHz grade in the same family. Differential analog inputs with built-in clamping reduce external component count.
The architecture combines input clamping, track-and-hold, and a proprietary multi-stage quantiser. Internal reference voltages and a low-jitter clock receiver reduce BOM cost. Digital outputs are CMOS-compatible and can be configured for 3.3V operation, simplifying interface to ASICs and DSPs.
Typical applications include professional SDTV video digitizers, medical imaging front-ends, IF sampling in communications receivers, and industrial inspection cameras. The wide bandwidth and low aperture delay make it suitable for any 10-bit, 30 MSPS analog interface.
When designing with this part, observe proper analog/digital ground partitioning and provide low-impedance 5V and 3.3V rails with adequate decoupling. The single-clock latency simplifies timing closure in FPGA-based video pipelines.

Ứng dụng tiêu biểu
TDA8763AM/3/C4 phù hợp cho 6 Áp dụngs: Professional SDTV Video Digitiser, Medical Imaging Front-End, IF Sampling in Communications Receivers, Industrial Inspection Camera, Test & Measurement Instrumentation, Legacy Industrial Control Digitiser.
Professional SDTV Video Digitiser
The TDA8763AM/3/C4's 30 MSPS sample rate exceeds the 27 MHz Nyquist requirement for SDTV (ITU-R BT.601 4:2:2) video digitisation, capturing composite or component analog video at 13.5 MHz pixel rate with 10-bit resolution. The single-clock-cycle conversion latency simplifies genlocking and frame-buffer alignment in FPGA-based video pipelines. Differential analog inputs with built-in clamping accept standard 1Vpp video directly, while the 5V analog and 3.3V digital supplies integrate easily with legacy video ASICs. Compared to the TDA8763AM/5 (50 MSPS), the /3 dissipates less power and costs less for cost-sensitive SDTV designs.

Medical Imaging Front-End
In ultrasound and digital X-ray front-ends, the TDA8763AM/3/C4 provides the 10-bit dynamic range and 30 MSPS throughput needed for beam-formed signal capture at baseband. Its single-clock latency enables deterministic timing for phased-array beam steering, while the commercial-grade -40C to +85C rating suits imaging carts and diagnostic consoles. Differential analog inputs reject common-mode noise from the transducer pre-amplifiers, and CMOS outputs interface cleanly to FPGA post-processing. The /3 variant balances cost and performance for entry-level ultrasound systems, while the /5 supports higher-end imaging.

IF Sampling in Communications Receivers
The TDA8763AM/3/C4 supports intermediate-frequency (IF) sampling in narrowband communications receivers, where analog IF signals in the 10-20 MHz range are digitised for downstream DSP demodulation. Its 10-bit resolution provides adequate dynamic range for FM and QPSK modulations, and the 30 MSPS sampling rate comfortably satisfies Nyquist at typical IF frequencies. The single-clock latency simplifies timing in synchroniser loops, while the SSOP-28 footprint saves PCB area compared to parallel ADCs in larger packages. Choose the /5 variant for wider-bandwidth IF or software-defined radio.

Industrial Inspection Camera
Machine-vision inspection cameras digitise analog sensor outputs at line rates up to 30 MHz with the TDA8763AM/3/C4, supporting standard CCD pixel clocks for VGA and SVGA resolutions. The single-clock-cycle latency enables real-time defect detection without buffering delay, and the CMOS outputs drive FPGA vision pipelines at 3.3V logic levels. Differential analog inputs reject common-mode noise from motor drives and switching power supplies typical in factory environments. The 28-SSOP package suits compact camera head electronics where board area is constrained.

Test & Measurement Instrumentation
Bench-top oscilloscopes, spectrum analysers, and data loggers leverage the TDA8763AM/3/C4 to digitise 10-bit wideband signals at 30 MSPS, providing sufficient bandwidth for audio, ultrasonic, and baseband RF measurement. The differential analog inputs pair naturally with front-end attenuators and AC-coupled instrumentation amplifiers. Single-clock latency preserves phase accuracy in FFT and correlation measurements. For higher-resolution test gear, designers can evaluate the MAX195BEWE (16-bit, 85 kSPS) as a complementary low-speed precision channel alongside the /3.

Legacy Industrial Control Digitiser
Long-lifecycle industrial PLCs and process-control modules built around the TDA8763AM/3/C4 family benefit from its 30 MSPS throughput and -40C to +85C operating range, enabling sensor-signal digitisation in factory automation. The single-clock latency simplifies deterministic real-time control loops, while the 28-SSOP package suits legacy through-hole-replacement PCB assemblies converted to surface-mount. Drop-in compatibility with the /4 (40 MSPS) and /5 (50 MSPS) speed grades lets designers scale throughput without layout changes. Evaluate modern replacements only when a board revision is otherwise required.

Ghi chú thiết kế
Provide a clean, low-impedance 5V analog rail (pin 1 and pin 28 tied together) and a separate 3.3V digital rail (pin 12). Use a ferrite bead or pi-filter between analog and digital supplies to prevent switching noise from the digital domain coupling into the analog front-end. Place 100 nF ceramic decoupling as close as possible to each supply pin and a 10 uF tantalum bulk cap near the IC.
Partition the PCB into analog and digital ground planes joined only at a single point beneath the IC (star-ground topology). Route analog input traces differentially with matched lengths to preserve common-mode rejection at the AINP/AINN inputs. Keep digital output traces (D0-D9, DRDY) away from analog input traces to avoid digital-to-analog crosstalk.
Do not drive the analog inputs beyond the supply rails; the internal clamping diodes can forward-bias and inject charge into the substrate. Ensure the CLAMP pin is configured per the datasheet to prevent signal distortion on large over-range inputs. Verify the clock input (CLK) meets the minimum amplitude and jitter requirements specified for the 30 MSPS speed grade.
