Overview

The 557G-06LF is a high-performance 2:4 differential clock multiplexer specifically designed for PCI Express Gen1 applications. It allows for the selection of one of two differential inputs to be distributed across four differential HCSL output pairs, supporting system clocking requirements with low jitter and high reliability.

Why Choose This Part

This device features low power consumption with a run current of approximately 55mA and a standby current of only 400uA. Its 20-pin TSSOP package provides a compact footprint for dense PCB layouts while offering HCSL-compatible outputs that simplify termination for PCI Express signaling standards.

Applications

PCIe System Clocking
Distributing reference clocks to multiple PCIe slots or endpoints in servers and workstations.
Network Switch Fabric
Providing synchronized clock signals across high-speed backplanes and interface cards.
Storage Area Networks
Managing clock distribution for high-speed disk arrays and controller boards.

Getting Started

When integrating the 557G-06LF, ensure the differential inputs are properly terminated and that the VDD supply is within the 3.135V to 5.5V range. Designers should follow standard high-speed layout practices, including controlled impedance traces for the HCSL outputs and proper decoupling of the power pins near the TSSOP-20 package.
