Z8623012PSC

Overview

The Z86230 is a stand-alone integrated circuit designed to process Extended Data Services (XDS) within the Vertical Blanking Interval (VBI) of NTSC or PAL video frames. It conforms to EIA-608A and EIA-744A standards, extracting Line 21 data to generate a Program Blocking signal or recover XDS packets. The device operates on a single 5V supply with a voltage range of 4.75 V to 5.25 V. It features an I2C serial interface for configuration and data output, supporting two selectable slave addresses. The component is available in 18-pin DIP and SOIC packages.

Feature Summary

• Processes XDS data from Field 2 of the VBI to provide violence blocking capabilities.
• Features fully programmable on-chip filters for selective XDS packet recovery.
• Supports both NTSC and PAL video standards through configurable operation modes.
• Provides a bidirectional I2C serial communication port for control and data retrieval.

Applications

• Television sets requiring V-Chip functionality
• Video Cassette Recorders (VCRs)
• Set-top boxes

Procurement Notes

Verify the specific package variant required, as the Z86230 series includes distinct part numbers for Through-Hole DIP and Surface-Mount SOIC configurations. Confirm that the ordering suffix aligns with the desired physical footprint and pin compatibility. Ensure the selected component meets the necessary environmental compliance standards for the target application region before finalizing procurement.

Selection Notes

Select the Z86230 when a dedicated hardware solution for Line 21 decoding is required without complex microcontroller overhead. Choose the DIP package for prototyping or through-hole manufacturing processes, while the SOIC variant suits automated surface-mount assembly lines. Ensure the design accommodates the external passive components specified for the loop filter and reference resistor circuits.

Part Context

The Z86230 belongs to the Z86230 family of video ICs manufactured by ZiLOG. It serves as a specialized decoder for television parental control systems. Other variants in this series, such as the Z8623012PSG, share identical core functionality but differ in packaging technology, offering flexibility for different PCB layout requirements.

Replacement Considerations

Direct replacements must maintain the 18-pin form factor and I2C interface. Verify pin-to-pin compatibility if substituting with other manufacturers' Line 21 decoders. Cross-reference the internal register map and timing characteristics to ensure seamless integration into existing firmware logic.
