WM8215CSEFL

Overview

The WM8215CSEFL is a 10-bit analogue front-end and digitiser IC designed for CCD or CIS sensors. It processes signals at up to 60MSPS using three independent channels, each featuring Reset Level Clamping, Correlated Double Sampling, and programmable gain/offset. Outputs are time-multiplexed into a single ADC and provided in 10-bit parallel format. The device operates on a 3.3V supply with typical power consumption of 400mW. It includes an internal 4-bit DAC for reference generation and is housed in a 32-lead QFN package.

Feature Summary

• 10-bit ADC with 60MSPS conversion rate
• Three-channel operation with CDS and programmable gain (9-bit) and offset (8-bit)
• Internal 4-bit DAC for reference level generation
• Serial control interface for register configuration

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors. Confirm the specific suffix 'CSEFL' denotes the standard tape and reel packaging variant. Check for end-of-life status as this model may be discontinued by Cirrus Logic. Ensure ESD precautions are observed during handling due to CMOS manufacturing process sensitivity.

Selection Notes

Select this component for applications requiring high-speed digitization of CCD or CIS outputs with integrated signal conditioning. Ensure the system supports 3.3V analog and digital supplies. Verify that the host controller can handle the serial interface timing constraints and 10-bit parallel data output. Consider thermal performance if operating near the upper temperature limit of 70°C.

Part Context

The WM8215 belongs to the Wolfson Microelectronics (now Cirrus Logic) WM821x series of CCD digitizers. It is functionally similar to the WM8216 but offers three processing channels instead of two. The part was originally manufactured by Wolfson Microelectronics plc before the company's acquisition by Cirrus Logic. It serves as a specialized interface between image sensors and digital processing units.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. The WM8216 is a related family member with two channels. Designers should verify pin compatibility and register map differences if considering alternative models from the same manufacturer or other vendors.
