ICS557G-06

Overview

The ICS557G-06 is a one-to-four differential to HCSL clock buffer designed for PCI-Express applications. It selects one of two differential input pairs and fans out to four pairs of differential outputs. The device operates at frequencies from 80 MHz to 200 MHz with a supply voltage of 3.135V to 3.465V. It features low power consumption, jitter of 100 ps peak-to-peak, and output skew of 50 ps. Packaged in a 20-pin TSSOP, it supports both HCSL and LVDS inputs.

Feature Summary

• One-to-four differential to HCSL clock buffering
• Supports 80 MHz to 200 MHz operating frequency
• Accepts LVDS or HCSL differential inputs
• Jitter specification of 100 ps (peak-to-peak)

Applications

• PCI-Express systems
• PC embedded systems

Procurement Notes

Verify the specific ordering suffix (e.g., LF for lead-free, T for tape and reel) against the manufacturer's datasheet to ensure correct packaging and environmental compliance. Confirm that the component source matches the original Integrated Circuit Systems (ICS) specifications now managed by Renesas Electronics Corporation.

Selection Notes

Select this component when a single differential clock source needs to drive four distinct loads in a PCIe architecture. Ensure the system design accommodates the required 50 ohm external load resistors at each output and provides adequate decoupling capacitors near the VDD pins for optimal performance.

Part Context

This part belongs to the ICS557 series of clock buffers originally manufactured by Integrated Circuit Systems (ICS). Following corporate acquisitions, the product line is now under Renesas Electronics Corporation. The ICS557G-06 specifically addresses high-speed interface timing requirements for legacy and current PCIe generation hardware designs.
