Z8622812PSC

Overview

The Z8622812PSC is a Line 21 Closed Caption Controller manufactured by Zilog. It operates within a supply voltage range of 4.75 V to 5.25 V and functions at temperatures between 0°C and +70°C. The device is housed in an 18-pin DIP package designed for through-hole mounting. It utilizes standard CMOS technology to provide the functional performance of a decoder module, requiring only composite video and horizontal timing signals as inputs.

Feature Summary

• Integrates Line 21 decoding functionality into a single self-contained integrated circuit
• Utilizes wired logic approach for function selection via input control signals
• Requires minimal external components, needing only composite video and timing inputs

Applications

• Closed captioning systems for television receivers
• Video processing units requiring Line 21 data extraction
• Consumer electronics with caption overlay capabilities

Procurement Notes

Verify component authenticity against Zilog specifications due to potential availability constraints. Confirm package integrity and pin alignment for the 18-pin DIP configuration. Ensure power supply stability within the 4.75 V to 5.25 V range during operation. Check for lead-free compliance requirements if applicable to current manufacturing standards.

Selection Notes

Select this component when a dedicated Line 21 decoder solution is required without complex external logic. Compare against other Z86228 variants for specific suffix differences regarding packaging or temperature ratings. Ensure system design accommodates the necessary composite video and horizontal timing signal inputs for proper operation.

Part Context

This part belongs to the Z86228 series of closed caption controllers. It represents a superintegration VLSI device designed to replace discrete decoder modules. The series focuses on cost-effective implementation of captioning features in consumer video equipment using standard CMOS processes.

Replacement Considerations

Z8622812PSG is a documented variant within the same product family. Verify if the suffix change indicates a difference in packaging material or environmental compliance before substitution.
