9DB1200CGLF-INT

Overview

The Renesas 9DB1200CGLF-INT is a PCI Express clock buffer and driver IC designed for high-speed digital systems. It features an integrated Phase-Locked Loop (PLL) to generate stable clock signals with low jitter. The device accepts a single differential input and provides twelve differential outputs, operating at frequencies up to 400MHz. It functions within a supply voltage range of 3.135V to 3.465V and supports HCSL output signaling. Manufactured by Renesas Electronics Corporation, this component is housed in a 64-TFSOP package suitable for surface mount applications.

Feature Summary

• Integrates a PLL-based clock buffer/driver with 1:12 input-to-output ratio
• Supports maximum operating frequency of 400MHz for PCIe applications
• Provides differential inputs and outputs using HCSL signaling standards
• Operates on a single 3.3V power supply (3.135V ~ 3.465V)

Applications

• PCI Express (PCIe) system clock distribution
• High-performance server motherboard timing solutions
• Networking equipment requiring precise clock synchronization

Procurement Notes

The manufacturer lists the 9DB1200C series as End-of-Life (EOL). Verification of current stock availability from authorized distributors is required before procurement planning. Alternative components should be evaluated for pin compatibility and electrical specifications to ensure system continuity.

Selection Notes

Select this component when a 1:12 fan-out buffer with integrated PLL is required for PCIe interfaces. Ensure the design accommodates the 64-TFSOP footprint and the specific 3.3V supply voltage constraints. Verify that the 400MHz maximum frequency meets the target bus speed requirements.

Part Context

This part belongs to the Renesas 9DB1200 family of PCIe clock generators and buffers. It is distinct from the 9DB202, which offers a 1:2 ratio, and the 9ZML1233E, which is a newer generation derivative with different packaging and enhanced jitter performance. The 'INT' suffix typically denotes industrial temperature range operation.

Replacement Considerations

Renesas recommends the RC19013A100GNG#KB0 as a manufacturer-recommended replacement. Designers should verify that the substitute component matches the 64-pin form factor and electrical characteristics of the original 9DB1200CGLF.
