AD9895KBCZRL

Overview

The AD9895KBCZRL is a highly integrated CCD signal processor featuring a complete analog front end and a full-function programmable timing generator. It includes a Correlated Double Sampler (CDS), Pixel Gain Amplifier (PxGA), Variable Gain Amplifier (VGA), Black Level Clamp, and a 12-Bit A/D Converter operating at up to 30 MHz. The device utilizes a Precision Timing core with 700 ps resolution for high-speed clock generation. It provides on-chip drivers for external crystals and horizontal clocks, supports electronic and mechanical shutter modes, and communicates via a 3-wire serial interface. Packaged in a 64-lead CSPBGA, it operates from -20°C to +85°C.

Feature Summary

• Integrates a 12-bit 30 MHz A/D converter with an analog front end comprising CDS, PxGA, VGA, and black level clamp.
• Features a Precision Timing core capable of generating high-speed CCD clocks with fine edge resolution.
• Includes on-chip output drivers for the Reset Gate (RG) and Horizontal Clocks (H1-H4).
• Supports flexible vertical transfer clocking and sensor gate pulses through a comprehensive timing generator.

Applications

• Digital Still Cameras
• Digital Video Camcorders
• Industrial Imaging

Procurement Notes

Verify the specific suffix KBCZRL against the manufacturer's current ordering guide to confirm package option and temperature range compatibility. Ensure that the 64-lead CSPBGA footprint matches the target PCB design constraints. Confirm RoHS compliance status as defined in the latest product specifications before finalizing procurement orders.

Selection Notes

Select this component when a 12-bit resolution and 30 MHz pixel rate are required for CCD signal processing. Compare against the AD9891 if a lower 10-bit resolution or 20 MHz speed suffices for the application. Evaluate power dissipation requirements under typical supply levels and verify that the 64-lead CSPBGA package fits within the available board space.

Part Context

This part belongs to the AD9891/AD9895 family of CCD signal processors designed for digital imaging applications. While the AD9891 offers 10-bit resolution at 20 MHz, the AD9895 variant provides enhanced 12-bit resolution and higher speed operation up to 30 MHz. Both share identical functional blocks and timing capabilities, differing primarily in ADC performance and maximum clock frequency.

Replacement Considerations

The AD9891KBCZRL serves as a compatible alternative within the same family, offering identical functionality but with reduced 10-bit resolution and a 20 MHz maximum clock rate. Verify that the system timing requirements can accommodate the lower speed and resolution specifications of the substitute part.
