Z8623012PSG

Overview

The Z86230 is a stand-alone NTSC Line 21 XDS decoder integrated circuit manufactured by ZiLOG. It processes Extended Data Services in Field 2 of the Vertical Blanking Interval to generate a Program Blocking signal or recover XDS data packets. The device operates on a single 5V supply, with a voltage range of 4.75 V to 5.25 V. It supports both Through Hole (DIP-18) and Surface Mount (SOIC-18) installation styles. The operating temperature range extends from 0°C to +70°C.

Feature Summary

• Extracts XDS data from composite video input for content advisory processing.
• Generates a selectable Program Blocking output based on user-defined ratings.
• Communicates via a bidirectional I2C serial interface with two selectable slave addresses.
• Includes fully programmable on-chip filters for selective XDS packet recovery.

Applications

• Television sets requiring V-Chip violence blocking capabilities.
• Video Cassette Recorders (VCRs) utilizing parental control features.
• Set-top boxes implementing content filtering standards.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches design requirements, as DIP and SOIC variants exist. Ensure compliance with RoHS directives if applicable to the specific manufacturing batch. Review preliminary specification status for any potential updates before finalizing integration into production hardware.

Selection Notes

Select this component when a dedicated, low-overhead solution for NTSC Line 21 decoding is required. It is suitable for designs needing minimal external components for XDS extraction. Consider the available I2C addressing options for system bus configuration. Verify that the target application operates within the specified 0°C to +70°C temperature range and standard 5V logic levels.
