9ZXL1930DKILF

Overview

The Renesas 9ZXL1930DKILF is a second-generation, enhanced-performance differential clock buffer derived from the DB1900Z architecture. It features 19 low-power HCSL (LP-HCSL) outputs driven by a single HCSL input, supporting frequencies up to 400 MHz. The device operates on a 3.3V supply with typical power consumption of 712 mW and exhibits zero propagation delay. Packaged in a 72-lead VFQFPN (10.0 x 10.0 mm) housing, it serves as a pin-compatible upgrade to the 9ZXL1930B, offering improved phase jitter performance suitable for critical QPI/UPI applications.

Feature Summary

• 19 LP-HCSL differential outputs with 1 HCSL differential input
• Zero propagation delay and support for spread spectrum inputs
• Fixed external feedback loop for low drift in QPI/UPI systems
• VFQFPN-72 package (10.0 x 10.0 x 1.0 mm)

Applications

• Intel QuickPath Interconnect (QPI)
• Ultra Path Interconnect (UPI)
• PCI Express (PCIe) clock distribution

Procurement Notes

Verify the suffix 'KILF' against official Renesas documentation to confirm RoHS compliance and lead-free status. Confirm moisture sensitivity level (MSL) requirements prior to PCB assembly. Check current availability and production cycle times, as delivery durations may vary based on manufacturing schedules.

Selection Notes

Select this component when upgrading from the 9ZXL1930B to require superior phase jitter performance without altering board layout. Ensure the design supports fixed external feedback for stability. Verify that the 72-pin VFQFPN footprint matches the target PCB design constraints.

Part Context

This part belongs to the 9ZXL1930 series of second-generation zero-delay clock buffers. It is specifically engineered as an enhanced derivative of the DB1900Z family, targeting high-speed processor interconnects where low jitter and signal integrity are paramount.

Replacement Considerations

The 9ZXL1930B is the direct predecessor; verify if the improved jitter specs are required. No other public substitutes are confirmed.
