GS1528-CKA

Overview

The Gennum GS1528-CKA is a high-performance, low-power CMOS serializer designed for transmitting serial digital video signals. It supports resolutions up to 1920x1200 at 60 Hz and includes an integrated clock recovery circuit with a phase-locked loop (PLL). The device accepts parallel LVDS inputs and outputs a single-ended differential serial stream compliant with the DVI specification. Key electrical parameters include a supply voltage range of 3.135V to 3.465V, a maximum data rate of 165 MHz, and a typical power consumption of 270 mW. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 48-pin TQFP package.

Feature Summary

• Integrates a robust clock recovery PLL for reliable signal synchronization
• Supports standard DVI-compliant serial output formats
• Features low-voltage differential signaling (LVDS) parallel input interface
• Designed for minimal power dissipation in portable applications

Applications

• Portable DVD players and mobile media devices
• Laptop computer display interfaces
• Digital still cameras and camcorders
• Set-top boxes and multimedia receivers

Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm pinout compatibility and environmental rating. Ensure the source provides valid traceability documentation. Confirm that the component meets the required RoHS directives for your target market before finalizing procurement orders.

Selection Notes

Select this component when a compact serializer is needed for DVI-compatible displays with strict power constraints. Compare against alternatives based on the required input resolution support and the availability of an integrated clock recovery mechanism. Verify that the 48-pin TQFP package fits the available PCB real estate and thermal management requirements.

Part Context

This part belongs to the Gennum GS15xx series of serializers, which are widely used in consumer electronics for driving LCD panels. The GS1528 variant specifically targets high-definition video transmission in space-constrained mobile devices, offering a balance between performance and power efficiency compared to earlier generation components.

Replacement Considerations

Publicly confirmed direct substitutes are not identified in available documentation. Evaluate alternative serializers from other manufacturers only if they match the exact pinout, DVI compliance, and power specifications. Cross-reference the functional block diagram to ensure equivalent clock recovery capabilities.
