AD9978BCPZRL

Overview

The AD9978BCPZRL is a dual-channel CCD signal processor designed for high-speed digital video applications. It integrates two complete analog front ends, each supporting pixel rates up to 65 MHz. Key internal components include black level clamping, correlated double sampling (CDS), a sample-and-hold amplifier (SHA), and a variable gain amplifier (VGA) with 10-bit resolution. The device features a 14-bit ADC per channel and utilizes a Precision Timing core for clock adjustments with 240 ps resolution at maximum speed. Data output is provided via a reduced-range LVDS interface, controlled through a 3-wire serial port.

Procurement Notes

Verify the specific suffix RL against the manufacturer's official documentation to confirm packaging details such as reel quantity or tape specifications. Ensure the operating temperature range of −25°C to +85°C aligns with the target system environment requirements before finalizing procurement.

Selection Notes

Select this component for systems requiring integrated CCD signal processing with precise timing control. The 1.8 V core supply voltage and space-saving 40-lead LFCSP package are suitable for compact designs. Verify that the required gain settings and CDS/SHA configurations meet the sensor interface needs.

Part Context

The AD9978BCPZRL belongs to the Analog Devices AD9978 family of CCD signal processors. This series is engineered to simplify the design of high-performance imaging systems by combining analog front-end functions and digitization into a single highly integrated solution.

Replacement Considerations

Consult the official datasheet for any pin-compatible alternatives within the AD9978 family. Verify functional equivalence regarding timing resolution and ADC performance if considering substitutes from other manufacturers.
