9ZML1233EKILF

Overview

The Renesas 9ZML1233EKILF is a second-generation enhanced performance clock buffer derived from the DB1200ZL architecture. It features 12 differential outputs and accepts differential HCSL inputs with a maximum frequency of 400 MHz. The device operates on a single 3.3V supply (3.135V to 3.465V) and consumes approximately 22 mA. It utilizes an LP-HCSL output signaling type and is housed in a 72-lead VFQFPN package measuring 10.0 x 10.0 mm. Designed for low phase noise applications, it supports spread spectrum input tolerance and includes software-adjustable input-to-output delay for transport management.

Feature Summary

• Second-generation DB1200ZL derivative with improved phase jitter performance over the 9ZML1232B.
• Features an SMBus Write Lockout pin to enhance device and system security.
• Provides software-adjustable input-to-output delay per channel for complex server topology management.
• Fixed external feedback mechanism maintains low drift for critical QPI/UPI applications.

Applications

• Server and high-performance computing systems.
• PCIe clock distribution networks.
• UPI/QPI processor interface timing.

Procurement Notes

Verify the specific suffix 'KILF' against the manufacturer's official datasheet to confirm packaging details and RoHS compliance status. Ensure the ordering quantity aligns with the factory reel size of 2500 units if purchasing new stock. Confirm moisture sensitivity level handling requirements prior to assembly.

Selection Notes

Select this component when a pin-compatible upgrade to the 9ZML1232B is required with superior jitter performance. It is suitable for designs needing fixed external feedback for stability alongside programmable delay adjustments. Verify that the 72-pin VFQFPN footprint fits the PCB layout constraints.

Part Context

This part belongs to the 9ZML1233 family of clock buffers. It serves as a specialized solution for modern server topologies requiring precise clock distribution with enhanced security features compared to previous generations.

Replacement Considerations

The 9ZML1233E is the base part number for this series. Verify if the 'KILF' suffix denotes a specific tape-and-reel packaging variant or environmental compliance option distinct from other suffixes like 'AKILF'.
