841S101EGILF

Overview

The 841S101EGILF is a PLL-based clock synthesizer from the FemtoClock series, designed for PCI Express applications. It generates a single differential HCSL output at 100 MHz from a 25 MHz crystal input. Key electrical parameters include a supply voltage range of 3.135 V to 3.465 V and an operating current of 80 mA. The device supports spread spectrum clocking for EMI reduction via I2C control. It operates within a temperature range of -40°C to +85°C and is housed in a 16-lead TSSOP package.

Feature Summary

• Generates 100 MHz differential HCSL clock from 25 MHz crystal reference
• Supports I2C programmable spread spectrum (-0.35% or -0.5%) for EMI reduction
• Compliant with PCI Express Gen 1, 2, and 3 jitter specifications
• Typical RMS phase jitter of 1.23 ps (12 kHz - 20 MHz) at 100 MHz

Applications

• PCI Express Gen 1, 2, and 3 clock generation
• Crystal-to-HCSL frequency synthesis
• Low jitter clock distribution systems

Procurement Notes

Verify RoHS compliance status through official Renesas documentation prior to procurement. Confirm package type is 16-TSSOP and ensure compatibility with -40°C to +85°C industrial temperature ratings. Check for specific ordering suffixes that may indicate packaging variations such as tube versus reel formats.

Selection Notes

Select this component when a fixed 100 MHz output from a 25 MHz crystal is required for PCIe interfaces. Ensure the design accommodates the 3.3V nominal supply voltage and 80 mA current consumption. Verify that the TSSOP-16 footprint fits the PCB layout constraints and that I2C lines are available for configuring spread spectrum settings if needed.
