9P936AFLF

Overview

The 9P936AFLF is a DDR I/DDR II phase-locked loop zero-delay buffer manufactured by Renesas Electronics. It functions as a clock fanout and buffer IC designed for memory applications, specifically supporting DDR and DDR2 technologies. The device features one circuit with a 1:06 input-to-output ratio, providing six differential outputs from a single differential input. It operates within a supply voltage range of 1.7V to 2.7V and supports frequencies up to 500MHz. The component is housed in a 28-SSOP package with a width of 5.30mm and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Zero-delay buffer architecture for DDR I/II synchronization
• 1:06 fanout ratio with differential input and output capabilities
• Maximum frequency support of 500MHz
• Operates on a 1.7V to 2.7V supply voltage

Applications

• DDR memory systems
• DDR2 memory interfaces
• Clock distribution networks requiring low skew

Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors or verifying specific stock status with suppliers. Designers should consider lifecycle management strategies due to the discontinued status.

Selection Notes

Select this part for applications requiring a zero-delay buffer for DDR or DDR2 memory controllers. Ensure the design accommodates the 1.7V–2.7V supply range and the 28-SSOP package dimensions. Verify that the 500MHz maximum frequency meets system timing requirements and that differential signaling is supported by the board layout.

Part Context

The 9P936AFLF belongs to the 9P936 series of clock buffers. It is distinct from similar models like the 9P936AGLF, which uses a TSSOP-28 package instead of SSOP. Both are part of Renesas's legacy portfolio for DDR memory clock generation and distribution.

Replacement Considerations

Direct pin-compatible replacements are limited due to the obsolete status. The 9P936AGLF offers similar functionality but in a TSSOP-28 package, requiring PCB footprint adaptation. Other modern clock buffers from Renesas or competitors should be evaluated for electrical compatibility and pin mapping.
