WM8215CSEFL/R

Overview

The WM8215CSEFL/R is a 10-bit analogue front-end and digitiser IC designed for CCD and Contact Image Sensor (CIS) applications. It processes analogue output signals at pixel sample rates up to 60MSPS. The device features three independent signal processing channels, each equipped with Reset Level Clamping, Correlated Double Sampling, and programmable gain and offset adjustment functions. Outputs from these channels are time-multiplexed into a single high-speed 10-bit Analogue-to-Digital Converter. Digital data is available in a 10-bit wide parallel format. The IC operates on a single 3.3V supply for both analogue and digital sections, consuming approximately 400mW of power.

Feature Summary

• 10-bit ADC with a conversion rate of 60MSPS
• Three-channel operation with Correlated Double Sampling (CDS)
• Programmable Gain Amplifier (9-bit resolution) and Offset Adjust (8-bit resolution)
• Internal 4-bit DAC for reference level generation and clamp control

Applications

• Digital Copiers
• USB2.0 compatible scanners
• Multi-function peripherals
• High-speed CCD/CIS sensor interface

Procurement Notes

Verify the component status as the WM8215 series may be discontinued or subject to limited availability. Confirm the specific ordering suffix '/R' indicates tape and reel packaging with a quantity of 3,500 units. Ensure compatibility with existing serial control interfaces and power supply requirements before procurement.

Selection Notes

Select this component for systems requiring high-speed digitization of CCD or CIS sensors with integrated signal conditioning. Ensure the design supports a 3.3V single supply voltage for both analogue and digital domains. Verify that the 32-lead QFN package dimensions fit the PCB layout constraints and that the thermal resistance characteristics are adequate for the expected operating temperature range of 0°C to +70°C.

Part Context

The WM8215 is part of the Wolfson Microelectronics (now Cirrus Logic) WM8215 family of CCD digitisers. It serves as an analogue front-end solution for image sensing applications. The 'CSEFL' designation refers to the 32-lead QFN package variant, while the '/R' suffix specifies the tape and reel packaging configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult official manufacturer documentation for end-of-life notifications or recommended alternative components within the same product family.
