WM8152SCDS/V - 16-Bit Single-Channel CIS/CCD AFE | Cirrus Logic
MPN: WM8152SCDS/V ✓ فعالWM8152SCDS/V نمای کلی
An analog front end, or AFE, is the interface between a sensitive image sensor and the digital signal-processing system. It conditions the small sensor signal, controls timing and correlated double sampling, performs analog-to-digital conversion, and presents digitized image data to an external processor. The WM8152SCDS/V belongs to the broader CMOS image-sensor interface and data-conversion hierarchy, combining sensor analog conditioning with a 16-bit digitizer.
The WM8152SCDS/V is identified as a single-channel device with 16-bit resolution and a maximum pixel rate of 12 MSPS. The manufacturer describes it as a CIS/CCD AFE with 4-bit wide output, making it suitable for scanners, imaging modules, and compact image-processing systems. Its 20-SSOP package provides a conventional surface-mount footprint for equipment where board area and production compatibility are important.
The analog supply is specified at 5 V, while the digital interface can operate from either 2.97 V to 3.63 V or 5 V. This flexibility allows the digitizer to operate with either 3.3 V or 5 V digital system logic when the external interface, timing, and signal-integrity requirements are satisfied. The device is designed for CMOS image-sensor signal chains rather than general-purpose audio or instrumentation conversion.
Typical uses include contact image sensors in scanners, CCD-based imaging assemblies, document-capture systems, and other pixel-oriented imaging products. In these applications, the AFE is placed close to the image sensor so that the weak analog signal is conditioned and digitized before long PCB traces introduce additional noise or distortion.
A key design consideration is separating the analog and digital return paths while keeping the sensor interface traces short. The power-supply network should provide low-impedance connections for both the 5 V analog rail and the selected digital rail, and the input and output routing should follow the manufacturer’s pin and layout guidance. The 225 mW listed power value should also be checked against the system’s thermal envelope during sustained operation.
This product record combines the manufacturer-described AFE function, the listed electrical and packaging characteristics, source links for documentation and purchasing, and practical application guidance for CIS and CCD imaging designs.

کاربردهای معمول
WM8152SCDS/V مناسب است برای 6 کاربردs: Contact Image Sensor Scanner, CCD Document Imaging, Industrial Imaging Module, Flatbed Scanner Electronics, Machine-Vision Camera Electronics, Optical Character Recognition Front End.
Contact Image Sensor Scanner
The WM8152SCDS/V fits contact image sensor modules because it is specifically described as a single-channel 16-bit CIS/CCD AFE with pixel rates up to 12 MSPS. Place the AFE close to the CIS output to minimize trace length, then provide its 5 V analog rail and either 2.97 V to 3.63 V or 5 V digital supply. Its 4-bit wide output can feed the scanner’s image processor when that processor accepts the device’s timing and output format. The 225 mW listed power value should be included in the module’s thermal and power-budget review, particularly during continuous scanning.
پیشنهادی
CCD Document Imaging
The WM8152SCDS/V can serve as the sensor-interface and digitizer in a CCD document-imaging channel where 16-bit conversion and a maximum 12 MSPS pixel rate are useful. Its integrated AFE role reduces the need to pair a CCD output with a separate general-purpose ADC and separate conditioning circuitry. The 5 V analog section and selectable 3.3 V or 5 V digital section allow the device to bridge a 5 V sensor front end to a compatible processor. Clocking, CCD timing, and pixel output capture must be verified against the sensor and manufacturer interface specifications.
پیشنهادی
Industrial Imaging Module
An industrial imaging module can use the WM8152SCDS/V when its sensor produces a compatible CCD or CIS analog stream and the required acquisition rate is no greater than 12 MSPS. The single-channel architecture is appropriate for line-scan or single-line sensor arrangements. Its 20-SSOP package supports compact surface-mount assemblies, while the 225 mW listed dissipation provides a concrete starting point for enclosure thermal analysis. Use a controlled analog ground region, short sensor traces, and separate routing for clock and digital output signals to preserve image quality.
پیشنهادی
Flatbed Scanner Electronics
The WM8152SCDS/V is suitable for flatbed scanner electronics built around a contact image sensor when its pixel timing and output interface match the chosen CIS. The 16-bit digitizer supports detailed image capture, and the selectable digital supply range permits integration with either 3.3 V or 5 V processor logic. The AFE should be positioned near the CIS connector and sensor return pins to minimize analog pickup and trace degradation. Validate the sensor clocking scheme, output enable behavior, and synchronization with the scanner’s motion-control electronics before releasing the production design.
پیشنهادی
Machine-Vision Camera Electronics
The WM8152SCDS/V can be evaluated for a compact machine-vision module that uses a single CCD or CIS output channel and does not require a sampling rate above 12 MSPS. Its integrated analog front end and 16-bit digitizer simplify the sensor-to-processor signal chain compared with a bare ADC implementation. The 5 V analog rail and configurable digital rail support mixed-voltage system partitioning, while the 20-SSOP package remains manageable for automated assembly. Camera calibration, exposure timing, trigger synchronization, and connector-level signal integrity remain system-level responsibilities.
پیشنهادی
Optical Character Recognition Front End
The WM8152SCDS/V is suitable for an OCR or text-recognition imaging path where a document sensor requires consistent analog-to-digital conversion at up to 12 MSPS. The 16-bit digitizer can retain more amplitude detail than lower-resolution converters, while the 4-bit wide output provides a defined interface to a subsequent digital engine. Keep the sensor, AFE, and associated bypass components away from motor and power-converter switching nodes. Validate illumination, sensor transfer response, exposure timing, and processor clocking as an integrated acquisition chain rather than treating the AFE as a stand-alone converter.

تفاوت‌های کلیدی
- Higher listed sampling rate for the /V ordering designation (در مقابلWM8152SCDS)

- Compatible 3.3 V or 5 V digital-supply options (در مقابلWM8152SCDS)
یادداشت‌های طراحی
Place the WM8152SCDS/V close to the CCD or CIS output connector, and keep the sensor-signal route short and away from clocks, switching nodes, and high-current return paths. Provide separate analog and digital ground regions with a deliberate connection strategy that follows the manufacturer’s recommended layout. Treat the 5 V analog rail as a sensitive rail and place its bypass capacitor at the device-side supply pin.
The WM8152SCDS/V requires a 5 V analog supply and supports a 2.97 V to 3.63 V or 5 V digital supply. Use low-impedance supply routing and local high-frequency decoupling at the relevant pins. Check the listed 225 mW power dissipation against the maximum operating temperature, enclosure temperature, and available board area; a 20-SSOP package benefits from uninterrupted nearby ground-plane copper.
Do not assume that the base WM8152SCDS and WM8152SCDS/V ordering names are interchangeable without checking the suffix-specific datasheet, because one listing describes the base family at 6 MSPS while the /V listing describes 12 MSPS. Also confirm pin functions, output timing, and package markings before replacing an installed device. Using the 20-SSOP footprint alone does not establish electrical drop-in compatibility.
Keep the analog sensor interface physically compact and route digital outputs separately from the sensor input path. If the AFE is mounted farther from the sensor than recommended, use a controlled-impedance or otherwise shielded connection strategy and validate the sensor output amplitude at the AFE input. Clock lines should have short return paths and appropriate termination where required by the system clock topology.
