AD9898KCP-20

Overview

The AD9898KCP-20 is a highly integrated CCD signal processor designed for digital still cameras and video camcorders. It combines an analog front end with a programmable timing generator in a 48-lead LFCSP package. The device supports pixel rates up to 20 MHz and includes a Correlated Double Sampler (CDS), a variable gain amplifier (VGA) with 6 dB to 40 dB range, black level clamp, and a 10-bit A/D converter. Operating temperatures range from –20°C to +85°C. Supply voltages are specified between 2.7 V and 3.6 V.

Feature Summary

• Integrates complete analog front end with A/D conversion and full-function programmable timing generator
• Features Precision Timing core allowing high-speed clock adjustment with 1 ns resolution at 20 MHz operation
• Includes on-chip sync generator with external sync option and electronic/mechanical shutter modes

Applications

• Digital Still Cameras
• Digital Video Camcorders

Procurement Notes

Verify the specific suffix KCP-20 against the manufacturer's current ordering guide to confirm the lead frame chip scale package (LFCSP) and temperature range specifications. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS inputs and outputs.

Selection Notes

Select this component when a single-chip solution for CCD signal processing is required. It eliminates the need for separate timing generators and analog conditioning circuits. Verify compatibility with the target CCD sensor's voltage levels and clock requirements before integration into the design.

Part Context

This part belongs to the AD9898 family of CCD signal processors. The KCP-20 designation indicates the specific package type and industrial temperature rating. Analog Devices provides evaluation boards and software tools to assist in the development of camera systems using this processor.

Replacement Considerations

Check the manufacturer's obsolescence notices for potential end-of-life status. Consult the official datasheet for any recommended pin-compatible or functionally equivalent successor devices within the same product family.
