GS1508-CKA

Overview

The GS1508-CKA is a first-generation very high-speed bipolar integrated circuit designed to drive two 75Ω coaxial cables. It operates as a line driver compliant with SMPTE standards, supporting data rates up to 1.485 Gbps. The component requires a 5V supply voltage and is housed in an 8-SOP package.

Feature Summary

• Designed for driving dual 75Ω coaxial cables
• Supports data transmission rates up to 1.485 Gbps
• Complies with SMPTE standards for video signal integrity

Applications

• High-speed digital video transmission systems
• SMPTE-compliant broadcast equipment
• Professional video distribution networks

Procurement Notes

Verify the specific datasheet version for the GS1508-CKA to confirm pinout compatibility and electrical characteristics against your design requirements. Ensure that the 8-SOP package dimensions match your PCB footprint. Cross-reference the manufacturer's official documentation to validate the operating temperature range and supply voltage specifications before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring the simultaneous transmission of signals over two separate 75Ω coaxial channels at standard definition or high-definition video speeds. It is suitable for applications where SMPTE compliance is mandatory and a single-chip solution for dual-channel driving is preferred over discrete transistor designs.

Part Context

The GS1508 series represents Gennum's early generation of high-speed bipolar drivers. While newer models like the GS1528 offer enhanced performance, the GS1508 remains a foundational component for legacy and specific professional video infrastructure requiring reliable 1.485 Gbps operation on dual coaxial lines.

Replacement Considerations

The GS1528-CKA is a documented second-generation alternative offering similar functionality with potential performance improvements. Verify pin-to-pin compatibility and electrical parameter alignment before substituting.
