9ZX21200AKLFT

Overview

The Renesas Electronics 9ZX21200AKLFT is a Z-buffer integrated circuit designed for high-performance clock distribution. It features one differential input and twelve differential outputs, operating within a frequency range up to 150 MHz. The device supports HCSL output signaling and functions as a zero-delay buffer with PLL capabilities. It operates on a supply voltage between 3.135 V and 3.465 V and is housed in a 56-VFQFN exposed pad package (8x8 mm). The component is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

• 1:12 Input-to-Output Ratio: Provides one differential input driving twelve differential outputs for extensive clock fanout.
• Zero-Delay Buffer Functionality: Incorporates a PLL to minimize propagation delay and skew between input and output clocks.
• HCSL Output Signaling: Utilizes HCSL output type suitable for low-power clock distribution applications.
• Compact Package: Encapsulated in a 56-VFQFN (8x8 mm) surface-mount package with an exposed pad.

Applications

• Intel QPI Clock Distribution
• PCI Express (PCIe) System Clocking
• High-Performance Computing Servers

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm tape-and-reel packaging versus tray options. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the 56-VFQFN footprint matches the target PCB design guidelines.

Selection Notes

Select this component when a single differential clock source requires expansion into twelve matched differential paths with minimal skew. Verify that the system power supply remains within the 3.135 V to 3.465 V range. Ensure the application environment stays within the 0°C to +70°C commercial temperature limits.

Part Context

This part belongs to the Renesas Z-buffer family, specialized for processor and memory interface clocking. It serves as a critical timing element in systems requiring precise synchronization between the CPU and peripheral components, specifically targeting Intel architecture interfaces.

Replacement Considerations

Check for updated revisions within the same series or pin-compatible derivatives from Renesas. Verify electrical compatibility if substituting with other 12-output differential buffers, ensuring output drive strength and voltage levels match the original design specifications.
