ADCS9888CVH-205

Overview

The ADCS9888CVH-205 is a high-performance analog front-end (AFE) designed for digital video applications, supporting resolutions up to UXGA. It integrates three independent channels capable of sampling at speeds up to 205 MSPS. The device features an 8-bit resolution and consumes 1.3 mW per channel. Packaged in a 128-pin QFP measuring 20x14 mm, it handles analog signal conditioning and digitization for professional video systems.

Feature Summary

• Integrates three independent high-speed sampling channels for simultaneous multi-signal processing
• Provides 8-bit resolution with low power consumption of 1.3 mW per channel
• Supports digital video applications up to UXGA resolution standards

Applications

• Professional digital video signal acquisition
• High-resolution video capture systems
• Multi-channel video monitoring equipment

Procurement Notes

Verify the manufacturer part number against official National Semiconductor documentation to confirm the specific speed grade suffix. Ensure the package type matches the required 128-QFP footprint. Cross-reference the datasheet revision to confirm pinout compatibility and electrical characteristics before integration into design schematics.

Selection Notes

Select this component when designing systems requiring three synchronized video inputs with moderate bit depth. The 205 MSPS sampling rate suits standard definition and early high-definition formats. Consider thermal management due to the dense QFP packaging if multiple units are deployed in confined spaces.

Part Context

This part belongs to the ADCS9888 family, which includes variants with different maximum sampling rates such as the 170 MSPS and 140 MSPS versions. All members share the same functional architecture and package outline but differ in timing specifications. The CVH suffix indicates the commercial temperature range and plastic package variant.

Replacement Considerations

The ADCS9888CVH-170/NOPB serves as a verified substitute within the same family, offering identical functionality at a reduced 170 MSPS sampling rate. Other variants like the 140 MSPS version also maintain pin compatibility. Verify that the lower bandwidth meets the specific video frequency requirements of the target application.
