XRD98L62ACV-F

Overview

The XRD98L62ACV-F is a CCD image digitizer featuring a 12-bit ADC with a maximum sampling rate of 30 MSPS. It integrates a differential Correlated Double Sampler (CDS), a 10-bit programmable gain amplifier (PGA) offering 0dB to 36dB gain, and digitally controlled black level auto-calibration. The device operates on a single 2.7V to 3.6V supply, consuming 70mA during conversion and 0.5mA in standby. It includes two serial-controlled 8-bit DACs for external control functions.

Feature Summary

• 12-bit resolution Analog-to-Digital Converter operating at up to 30 MSPS
• Differential CDS with 10-bit PGA providing 0dB to 36dB gain range
• Digital noise suppression filter and programmable pixel averager for calibration
• Two 8-bit utility DACs for controlling external analog signals

Applications

• Mega pixel Digital Still Cameras
• Digital Camcorders
• Line Scan Cameras
• High Speed Scanners
• Industrial/Medical Cameras

Procurement Notes

Verify the specific suffix ACV indicates the -15°C to 70°C commercial temperature range and 3.0V nominal supply operation. Confirm package integrity for the 48-lead TQFP form factor. Check current availability status as this component may be subject to limited stock or end-of-life conditions from the manufacturer.

Selection Notes

Select the XRD98L62ACV-F for applications requiring low power consumption and high dynamic range in portable imaging devices. Ensure the system design supports the required 3-wire serial interface for register configuration. Verify that the input signal levels fit within the CDS input range and that the 3.0V supply voltage aligns with the DVDD and AVDD requirements.

Part Context

Manufactured by MaxLinear (formerly Exar Corporation), this component belongs to the XRD98 series of CCD image digitizers. It is designed to replace discrete CDS and ADC solutions in compact camera modules. The device simplifies system architecture by integrating signal conditioning and conversion into a single 48-pin TQFP package.

Replacement Considerations

Direct pin-compatible replacements are not explicitly listed in the provided documentation. Evaluate other parts within the XRD98 family or newer MaxLinear imaging digitizers for functional equivalence. Verify compatibility with existing timing circuits and serial interface protocols before substitution.
