ICS9P946AFLF

Overview

The ICS9P946AFLF is a clock buffer integrated circuit manufactured by Renesas Electronics Corporation, designed for memory and DDR/DDR2 applications. It features two circuits with a 1:06 input-to-output ratio and supports differential input/output signals. The device operates at a maximum frequency of 533 MHz with a 3.3V supply voltage. It is housed in a 48-BSSOP package (7.50mm width) and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports DDR and DDR2 memory interfaces
• Differential input and output configuration
• Maximum frequency of 533 MHz
• Single 3.3V power supply operation

Applications

• DDR memory systems
• DDR2 memory systems
• High-speed digital signal processing

Procurement Notes

Verify the specific package variant and lead times with authorized distributors, as availability may vary. Confirm RoHS compliance status through official documentation before procurement. Ensure the 48-SSOP footprint matches the target PCB design requirements.

Selection Notes

Select this component for designs requiring low-jitter clock distribution to multiple DDR or DDR2 memory modules. Ensure the system environment stays within the 0°C to 70°C operating range. Verify that the 3.3V supply rail is stable and meets the noise specifications outlined in the datasheet.

Part Context

This part belongs to the Application Specific Clock/Timing category from Renesas Electronics. It serves as a specialized buffer for high-speed memory interfaces, distinct from general-purpose clock generators or oscillators.

Replacement Considerations

Check for direct pin-compatible alternatives within the Renesas portfolio that support similar DDR frequencies. Verify if newer generations offer improved jitter performance or extended temperature ranges while maintaining the 48-SSOP package.
