Overview
The AD9943KCPZRL is a complete analog signal processor for CCD applications, featuring a single-channel architecture designed to sample and condition outputs of interlaced and progressive scan area CCD arrays. It integrates a correlated double sampler (CDS), a digitally controlled variable gain amplifier (VGA) with 6 dB to 40 dB range, and a black level clamp. The device includes a 10-bit, 25 MSPS A/D converter with no missing codes guaranteed. It operates from a single 3 V supply, typically dissipating 79 mW in normal mode and 150 µW in power-down mode. The component is housed in a space-saving 32-lead 5 mm × 5 mm LFCSP package.
Feature Summary
- Integrates a 25 MSPS correlated double sampler (CDS) for noise rejection.
- Includes a programmable variable gain amplifier (VGA) with 10-bit resolution control.
- Features a low-noise optical black clamp circuit for DC restoration.
- Utilizes a 3-wire serial digital interface for internal register programming.
Applications
- Digital still cameras
- Digital video camcorders
- PC cameras
- Portable CCD imaging devices
- CCTV cameras
Procurement Notes
Verify the specific ordering suffix RL indicates reel packaging when sourcing components. Confirm that the AD9943 variant provides 10-bit resolution, distinct from the 12-bit AD9944 model. Ensure compatibility with the required 32-lead LFCSP footprint during procurement planning.
Selection Notes
Select this component for designs requiring a complete analog front end for CCD sensors. The AD9943 offers 10-bit resolution, whereas the AD9944 provides 12-bit resolution; choose based on image quality requirements. Verify that the system timing generator can provide the necessary SHP, SHD, and DATACLK signals for proper operation.
Part Context
The AD9943KCPZRL belongs to the AD9943/AD9944 family of complete analog signal processors. These devices are specifically engineered for CCD imaging applications, combining signal conditioning and digitization into a single chip. The KCPZ suffix denotes the commercial temperature range and LFCSP package type.
Replacement Considerations
The AD9943KCPZ is a tray-packaged equivalent of the same functional device. The AD9944 series offers identical functionality but with 12-bit ADC resolution. No other direct substitutes are documented in the provided datasheet.
