Overview

The 9DBL0452BKILF is a 4-output, 3.3V PCIe Zero-Delay and Fanout Buffer designed to meet PCIe Gen1 through Gen5 requirements. It supports a maximum frequency of 200MHz and utilizes HCSL differential signaling to maintain high signal integrity in high-speed data paths. This component is ideal for systems requiring low-power clock distribution with flexible PLL or bypass modes.

Why Choose This Part

This buffer offers extreme flexibility with an integrated PLL that can be bypassed to function as a pure fanout buffer. Its low-power design consumes only 30mA with all four outputs active at 100MHz, and the SMBus interface allows for fine-tuned configuration of output enables and internal settings. The 5x5mm VFQFPN package provides a compact footprint with excellent thermal characteristics for high-density PCBs.

Applications

PCIe Riser Cards
Distributing clock signals across expansion cards while maintaining strict phase jitter requirements for Gen4 and Gen5 standards.
NVMe Storage Systems
Providing synchronized, low-latency clocking for high-density storage arrays and flash controllers.
Networking Infrastructure
Clock distribution for high-speed switches and routers that utilize PCIe control planes.
Industrial Computing
Reliable clocking for embedded processors and FPGA-based accelerators in industrial control environments.

Getting Started

When designing with the 9DBL0452, ensure the HCSL outputs are correctly terminated with 50-ohm resistors to ground if not integrated into the receiver. Use the SMBus interface to configure the PLL bandwidth and individual output enables during the power-up sequence. Refer to the Renesas Timing Commander software tool for calculating register settings and simulating phase jitter performance.
