9FG104EGLF

Overview

The Renesas Electronics 9FG104EGLF is a clock synthesizer and jitter cleaner designed for PCI Express Gen2 applications. It features four HCSL outputs with a maximum frequency of 400 MHz, driven by a crystal or clock input up to 27.5 MHz. The device operates on a single 3.3V supply (3.135V to 3.465V) and consumes approximately 106 mA. Packaged in a 28-TSSOP, it functions within a commercial temperature range of 0°C to +70°C. This component integrates PLL technology to generate precise timing signals for high-speed digital interfaces.

Feature Summary

• Four-output HCSL clock synthesizer optimized for PCIe Gen2 systems
• Maximum output frequency of 400 MHz with crystal or clock input
• Single 3.3V power supply operation with 106 mA typical current draw
• Available in 28-TSSOP surface-mount package

Applications

• PCI Express Gen2 system clock generation
• Intel CPU server platforms
• SATA interface timing

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. The 'EGLF' designation corresponds to the 28-TSSOP package and commercial operating range. Confirm RoHS compliance status via the manufacturer's environmental declaration before integration. Cross-reference the Mouser part number 972-9FG104EGLF for accurate sourcing details.

Selection Notes

Select this component when designing for PCI Express Gen2 requirements needing four differential or single-ended HCSL outputs. Ensure the design supports a 3.3V supply rail and fits within the 0°C to +70°C thermal envelope. Compare against the 9FG108EGLF if eight outputs are required, noting the change to a 48-TSSOP package and higher current consumption.

Part Context

This part belongs to the 9FG104 series of clock synthesizers from Renesas. It serves as a successor or variant to earlier ICS9FG104 models, maintaining compatibility with legacy designs while offering updated packaging and manufacturing processes. The device is distinct from the 9FG104EGILFT, which offers an extended industrial temperature range.

Replacement Considerations

The 9FG104EGILFT provides the same electrical functionality but supports an extended temperature range of -40°C to +85°C. For applications requiring more outputs, the 9FG108EGLF offers eight outputs in a 48-TSSOP package. Verify pinout compatibility when substituting these variants.
