AD9979BCPZ

Overview

The AD9979BCPZ is a highly integrated CCD signal processor designed for high-speed digital video camera applications, specified at pixel rates up to 65 MHz. It combines a complete analog front end with an analog-to-digital converter and a programmable timing driver. The device features a Precision Timing core providing approximately 240 ps resolution at 65 MHz operation. Key specifications include a 14-bit ADC operating at 65 MSPS, a 10-bit variable gain amplifier (VGA) with gains from 6 dB to 42 dB, and a correlated double sampler (CDS). The unit operates on a 1.8 V analog and digital core supply voltage and includes internal LDO regulator circuitry. It is housed in a 7 mm × 7 mm, 48-lead LFCSP package.

Feature Summary

• Integrates a complete analog front end with black-level clamping, CDS, VGA, and a 14-bit ADC.
• Features a Precision Timing core for high-speed clock adjustment with fine edge resolution.
• Includes on-chip 3 V horizontal and RG drivers capable of directly driving CCD inputs.
• Supports flexible timing generation through a 3-wire serial interface.

Applications

• Professional HDTV camcorders
• Professional/high-end digital cameras
• Broadcast cameras
• Industrial high-speed cameras

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 48-lead LFCSP package variant when sourcing. Confirm that the component meets the required operating temperature range of −25°C to +85°C for the intended environment. Ensure compatibility with the 1.8 V core supply and 3.3 V driver supplies during system design validation.

Selection Notes

Select this component for systems requiring a fully integrated CCD signal processing solution with precise timing control. Consider the 14-bit resolution and 65 MHz speed for high-quality image capture needs. Evaluate the power consumption characteristics against system thermal constraints, particularly under maximum load conditions for the horizontal drivers.

Part Context

The AD9979 belongs to Analog Devices' portfolio of CCD signal processors, specifically engineered for professional imaging applications. It consolidates functions typically distributed across multiple discrete components into a single IC, simplifying board layout and reducing overall system complexity for high-end video equipment manufacturers.
