XRD98L59AIG

Overview

The XRD98L59AIG is a CCD image digitizer manufactured by MaxLinear, Inc., housed in a 28-pin TSSOP package. It integrates Correlated Double Sampling (CDS), a Programmable Gain Amplifier (PGA), and a 10-bit Analog-to-Digital Converter (ADC). The device supports a sampling rate of 20 MHz with a maximum supply voltage of 5.5 V. It operates within a temperature range of -40°C to +85°C. This component is designed for consumer circuit applications, specifically targeting digital still cameras and camcorders requiring high-speed analog signal processing.

Feature Summary

• Integrated 10-bit ADC with 20 MHz sampling rate
• Built-in Correlated Double Sampling (CDS) and Programmable Gain Amplifier (PGA)
• Compatible with Exar AFE video chips via adapter boards
• Operates on a single 3.3V to 5.5V power supply

Applications

• Digital Still Cameras (DSC)
• Camcorders
• CCD Image Digitization Systems

Part Context

The XRD98L59AIG belongs to the XRD98L59 series of CCD image digitizers. It serves as a direct replacement or evaluation target for legacy Exar AFE products, such as the HD49323a, allowing designers to substitute existing vendor components without redesigning the PCB footprint using specific adapter modules like the XRD98L59_CAM_HD49323A_EVAL.

Replacement Considerations

For pin-compatible substitution, the XRD98L59 can replace Exar's HD49323a when used with the designated surface mount adaptor board. Designers should verify that the target application supports the 20 MHz sampling rate and 10-bit resolution specifications provided by this component.
