TDA8763AM/5/C5 - 10-bit 50MSPS ADC, 28-SSOP | NXP
MPN: TDA8763AM/5/C5 ✗ Cuối đờiTDA8763AM/5/C5 Tóm tắt
An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts continuous analog voltages into discrete digital codes, forming the bridge between the analog front end and digital processing stages. Within the broader taxonomy, this device belongs to: ADC -> data converter -> data acquisition IC -> mixed-signal IC -> semiconductor. The sigma-delta topology oversamples the input at a rate much higher than the Nyquist frequency and uses noise shaping to push quantization noise out of band, trading analog input bandwidth for high effective resolution.
Key features include 10-bit resolution, sampling up to 50 MHz, DC sampling capability, single-clock-cycle latency, no missing codes, an In-Range (IR) CMOS output with TTL/CMOS-compatible levels, and 9.4 effective bits at a 4.43 MHz full-scale input with a 40 MHz clock. These characteristics indicate the device is engineered for video-rate digitization where high SNR and clean mid-frequency performance are required. The IR output assists downstream clamping or gain control logic.
The part uses a switched-capacitor input structure with an internal reference. Its single-clock-cycle conversion latency simplifies synchronization in pipelined architectures, and the wide analog input bandwidth supports standard video frequencies (e.g., 4.43 MHz PAL chroma). Per the manufacturer datasheet, the device operates from a single supply and provides CMOS-level digital outputs for direct interfacing with standard ASICs, FPGAs, or DSPs.
Typical applications include video digitizers, professional broadcast equipment, industrial imaging, medical ultrasound front ends, and high-speed instrumentation. The 50 MSPS rate is well matched to standard-definition and intermediate-frequency video ADCs.
When designing with this device, place input decoupling close to the supply pins and provide a low-impedance analog input drive. The SOT341 SSOP28 package has moderate thermal resistance and requires standard 4-layer PCB layout practice for mixed-signal integrity.

Ứng dụng tiêu biểu
TDA8763AM/5/C5 phù hợp cho 6 Áp dụngs: Standard-Definition Video Digitizer, Industrial Imaging Front End, Medical Ultrasound Receive Channel, High-Speed Instrumentation Digitizer, Professional Broadcast Equipment, Communication IF Sampling.
Standard-Definition Video Digitizer
The TDA8763AM/5/C5 fits standard-definition video digitization because its 50 MSPS sampling rate exceeds the 14.3 MHz chroma bandwidth required for 4fsc PAL digitizers, and its 9.4 ENOB at 4.43 MHz full-scale input delivers sufficient SNR for broadcast-grade video. The single-clock-cycle latency simplifies sync with downstream MPEG encoders, and the In-Range CMOS output drives a video ASIC or FPGA capture port directly. Placed between the analog front end and a digital encoder, it removes the need for an external clamping gain stage. Compared to a discrete flash ADC plus op-amp chain, this single-chip solution reduces board area and BOM cost while keeping noise within broadcast tolerances.

Industrial Imaging Front End
For industrial line-scan and area-scan cameras, the TDA8763AM/5/C5 provides 10-bit resolution at up to 50 MSPS, sufficient for monochrome machine vision at moderate line rates. The DC sampling capability simplifies calibration routines that require DC-coupled inputs, and the no-missing-codes guarantee keeps the histogram clean for defect-detection algorithms. The 28-SSOP package is footprint-compatible with most 28-pin ADC layouts, easing PCB migration. Power consumption is moderate, allowing fanless industrial enclosure designs. Its IR output can be wired to a CPLD gain controller to extend dynamic range without adding an external detector.

Medical Ultrasound Receive Channel
The TDA8763AM/5/C5 is used in entry-level ultrasound receive paths where its 10-bit 50 MSPS conversion digitizes the post-TGC analog signal at sufficient fidelity for B-mode imaging. The single-clock-cycle latency aligns cleanly with the beamformer clock domain, allowing direct sample-and-hold into the delay-and-sum pipeline. Its CMOS/TTL-compatible outputs interface with legacy ultrasound ASICs without level translation. While not suitable for harmonic or premium 12-bit imaging, the part remains viable in cost-engineered portable ultrasound SKUs. The IR output supports automatic gain reduction in saturated channels.

High-Speed Instrumentation Digitizer
In test and measurement instruments such as oscilloscope front ends and waveform digitizers, the TDA8763AM/5/C5 can serve as a low-cost 50 MSPS capture channel where 10-bit resolution is acceptable. Its DC sampling allowed specification simplifies calibration of DC offsets, and the no-missing-codes guarantee preserves monotonicity for amplitude measurements. Driving the analog input from a low-impedance op-amp buffer ensures the converter's switched-capacitor input does not distort fast transients. The In-Range flag can trigger an external attenuator to extend dynamic range.

Professional Broadcast Equipment
The TDA8763AM/5/C5 is qualified into legacy broadcast routing and processing gear where its 10-bit 50 MSPS performance meets composite and component video digitizer requirements. The TTL/CMOS-compatible outputs interface directly with ECL-to-CMOS translatorless backplanes in older routers, simplifying retrofit designs. Its wide operating temperature range (-40 C to +85 C) suits outdoor head-end and satellite uplink environments. The 28-SSOP package fits the compact PCB assemblies typical of 1U rack-mount frames.
Được đề xuất
Communication IF Sampling
For intermediate-frequency sampling in narrowband communication receivers, the TDA8763AM/5/C5 captures IF signals up to 4.43 MHz with sufficient dynamic range for demodulation in DSP. The 50 MSPS clock supports digital downconversion architectures and sigma-delta noise shaping pushes quantization noise out of the signal band. Its single-clock-cycle latency simplifies the demodulator's timing recovery loop. As a cost-engineered 10-bit option, it is well suited to fixed-function narrowband radio modules.

Ghi chú thiết kế
Use a 4-layer PCB with continuous ground plane beneath the 28-SSOP footprint. Place 0.1 uF ceramic decoupling caps within 3 mm of each VDD pin and a single 10 uF tantalum or ceramic bulk cap on the analog supply. Keep digital output traces short and routed away from the analog input pin to minimize digital coupling into the switched-capacitor input.
Drive the analog input through a low-impedance op-amp buffer (e.g., less than 50 ohm output impedance at the converter's input bandwidth). The switched-capacitor input structure creates transient charge injection glitches at the clock edges; a series input resistor of 10-33 ohm dampens kickback. For video applications, AC-couple with 0.1 uF and provide DC restore through the IR feedback loop.
Do not assume the /5 grade is interchangeable with /3 or /4 grades without verifying timing against your specific clock frequency. Although the pinout and basic functionality are identical, parametric differences (sampling edge skew, analog input bandwidth) may matter in marginal timing budgets. Always revalidate SNR and SFDR at the actual fclk used in your design before substituting parts in production.
