WM8233GEFL/V - 16-Bit 6-Channel 70 MSPS AFE | Cirrus Logic
MPN： WM8233GEFL/V ✗ 停產WM8233GEFL/V 概覽
An analog front end, or AFE, is an interface IC that conditions, samples, and converts sensor signals into digital data. The AFE category sits between the sensor and the digital processing system: CCD or CIS outputs enter the AFE, programmable analog processing prepares those signals, and the resulting high-speed data is delivered to a processor or image pipeline. WM8233 belongs to this broader class of high-speed mixed-signal semiconductor and sensor-interface IC.
The WM8233 provides six analog signal-processing channels, each incorporating reset-level clamping, correlated double sampling, sample-and-hold circuitry, and programmable gain according to the manufacturer datasheet. Its 16-bit conversion resolution preserves fine amplitude detail in imaging systems. Programmable operating modes, sensor timing generation, and selectable CMOS or LVDS data outputs allow the interface to be adapted to different sensor and back-end requirements.
WM8233GEFL/V operates from a 2.97 V to 3.63 V analog supply range. The manufacturer documentation also describes a separate digital supply, supporting independent control of analog and digital power domains. This separation can help designers isolate sensitive analog processing from digital-interface noise while maintaining a common 56-pin package and compact 8 mm by 8 mm footprint.
Typical applications include linear CCD scanners, contact image sensors, document imaging systems, industrial inspection equipment, and other multichannel imaging platforms. Six integrated channels are particularly useful where multiple sensor outputs must be sampled coherently. The timing-generation and data-output functions reduce the external control burden associated with synchronizing sensor transfer, sampling, and digital readout.
Designers should place input, reference, and digital-output connections for controlled impedance, maintain the analog and digital return paths separately, and use the exposed thermal pad with an appropriate PCB ground and thermal layout. The pin and exposed-pad connections should follow the manufacturer pin-description table and recommended land pattern exactly. Because this device is listed as NRND, new designs should confirm lifecycle and sourcing requirements before committing to production.
This product page consolidates the verified channel count, resolution, sampling-rate descriptions, supply range, package, lifecycle status, and sourcing information. It also distinguishes electrically similar Cirrus Logic devices from verified drop-in replacements and provides practical guidance for evaluating the WM8233 in CCD and CIS imaging systems.

典型應用
WM8233GEFL/V 適用於 6 應用s: CCD Document Scanners, Contact Image Sensor Systems, Industrial Inspection Equipment, Machine-Vision Imaging Modules, Linear Array Imaging Systems, High-Speed Optical Measurement.
CCD Document Scanners
The WM8233GEFL/V is well suited to CCD-based document scanners because six analog channels can acquire related sensor outputs while correlated double sampling reduces reset noise and offset-related effects. Its 16-bit digitization preserves subtle grayscale differences, and operation up to 22.5 MSPS per channel supports high-speed image transfer. Integrated timing generation helps synchronize sensor readout with the digital back end. The 56-pin VFQFN also keeps the six-channel interface compact, although routing, reference stability, and exposed-pad thermal management remain essential.
推薦
Contact Image Sensor Systems
For contact image sensor modules, the WM8233GEFL/V provides six synchronized analog channels with programmable gain, reset-level clamping, and correlated double sampling. These functions are valuable when a CIS output contains reset offsets or requires gain adjustment before digitization. The 2.97 V to 3.63 V analog supply supports a compact imaging board, while separate CMOS or LVDS readout choices help match the downstream processor interface. System validation should confirm sensor timing, input bandwidth, channel order, and output impedance against the selected CIS.
推薦
Industrial Inspection Equipment
Industrial inspection systems benefit from the WM8233GEFL/V when several sensor lines must be digitized at consistent resolution and rate. Six 16-bit channels reduce the number of separate converter functions required on a multichannel optical module, while programmable timing generation can coordinate image transfer. The CMOS and LVDS output options provide flexibility between short-distance board links and longer cable-based interconnects. Because the WM8233 is marked NRND, equipment builders should verify availability, lifecycle, and any supported migration before finalizing a new platform.
推薦
Machine-Vision Imaging Modules
The WM8233GEFL/V can serve as the imaging AFE in a machine-vision module requiring multiple synchronized sensor channels and 16-bit data resolution. Correlated double sampling and programmable gain support extraction of small optical signals, while the 22.5 MSPS per-channel pixel rate provides a defined acquisition ceiling. Designers should budget analog gain distribution for sensor full-scale range and use controlled-impedance routing for CMOS or LVDS outputs. Stable reference design and careful analog-ground isolation are critical for preserving measurement repeatability.
推薦
Linear Array Imaging Systems
Linear-array imagers often require several outputs to be sampled with consistent reset timing and low added noise. The WM8233GEFL/V addresses that requirement with six analog processing channels, correlated double sampling, sample-and-hold operation, and programmable gain. Its separate analog and digital supply domains help isolate sensitive front-end circuitry from interface switching, and integrated timing generation reduces the external sequencing burden. A complete design must verify the sensor's required clock phases, output coupling method, channel mapping, and available board area for the exposed-pad package.
推薦
High-Speed Optical Measurement
Optical measurement systems can use the WM8233GEFL/V to digitize multiple detector outputs at 16-bit resolution and up to 22.5 MSPS per channel. The six-channel architecture is useful when several photodiode or line-sensor outputs require synchronized sampling, while programmable gain allows the analog range to be adapted to the detector. Programmable sensor timing and CMOS or LVDS outputs support integration with external timing and processing electronics. Achievable precision still depends on reference-voltage quality, analog-noise performance, PCB contamination control, and calibration stability.

- Compact exposed-pad integration (對比WM8231GEFL/RV)
設計說明
Follow the Cirrus Logic recommended land pattern and pin-description table for the 56-pin VFQFN with exposed pad. Keep the analog inputs short, route them away from CMOS and LVDS output transitions, and provide local input and bypass capacitance at the corresponding supply pins. The exposed pad should connect to the intended ground and thermal plane according to the manufacturer package drawings; its electrical and thermal roles should not be treated as interchangeable.
Preserve analog and digital signal integrity by preventing high-speed return currents from crossing the sensitive CCD or CIS input region. Use a continuous reference plane where practical, place decoupling capacitors near their associated pins, and verify that LVDS or CMOS trace impedance matches the receiving device. The separate analog and digital supply domains should meet only at an intentional grounding point, with current paths evaluated under maximum clock and data activity.
Do not treat the distributor descriptions of 70 MSPS and 22.5 MSPS as interchangeable ratings. The manufacturer datasheet describes pixel sample rates up to 22.5 MSPS per channel, while distributor listings characterize the family as a 70 MSPS AFE. Confirm which figure applies to the specific operating mode, sensor timing, output configuration, and clock plan before selecting the device or designing cable and interface bandwidth.
Validate the complete acquisition chain with the selected CCD or CIS rather than relying only on nominal AFE specifications. Check input amplitude, reset timing, correlated-double-sampling intervals, programmable gain range, channel ordering, and output clocking. When multiple WM8233 devices share the serial interface, assign unique IDs through DSLCT2 and DSLCT1 and verify bus contention, termination, and trace length with the complete device population.
Estimated: thermal performance depends on actual dissipation, board copper, ambient temperature, and the assembled land pattern, so calculate it using the final PCB rather than a package label alone. Use the exposed pad as a controlled thermal path and minimize thermal resistance into the internal ground plane. Confirm the manufacturer maximum junction and ambient temperature limits before selecting this NRND device for a new industrial or automotive design.
