PI6C557-06LIE

Overview

The PI6C557-06LIE is a single-circuit clock generator manufactured by Diodes Incorporated, designed for PCI Express applications. It operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 200MHz. The device features HCSL input and output interfaces with a 2:4 input-to-output ratio. It is housed in a 20-TSSOP package (0.173" width) suitable for surface mount installation. The component functions without an internal PLL and supports differential signaling on both input and output paths.

Feature Summary

• PCI Express compliant clock generation with 200MHz maximum frequency
• HCSL input/output interface supporting differential signaling
• Single circuit configuration with 2:4 input-to-output ratio
• Operates within -40°C to +85°C temperature range

Applications

• PCI Express system clock distribution
• High-speed digital interface timing
• Server and storage backplane designs

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through official datasheets before procurement. Ensure the 20-TSSOP footprint matches the target PCB layout requirements.

Selection Notes

Select this component when a PCIe-compliant clock generator with HCSL I/O is required. The 2:4 ratio allows one input source to drive four outputs. Verify that the external crystal or oscillator matches the 200MHz operational limit and that the 3.3V nominal supply aligns with the specified 3.135V to 3.465V operating window.

Part Context

This part belongs to the PI6C557 series of clock generators from Diodes Incorporated. These devices are engineered specifically for high-speed serial link applications, providing stable clock signals for peripheral components in computing infrastructure.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as other PI6C557 variants with different output counts or packaging options, ensuring electrical parameters remain identical.
