841S04CGILF

Overview

The Renesas 841S04CGILF is a PLL-based clock generator designed for PCI Express applications. It generates a 100MHz HCSL clock output from a 25MHz reference input, which can be derived from an external source or an on-chip crystal oscillator. The device features four 0.7V current mode differential HCSL output pairs and supports I2C configuration with readback capabilities up to 400kHz. Key electrical parameters include a maximum RMS period jitter of 3ps, maximum output skew of 70ps, and maximum cycle-to-cycle jitter of 35ps. It operates within a -40°C to 85°C ambient temperature range and utilizes a lead-free RoHS 6 compliant package.

Feature Summary

• Generates 100MHz HCSL clock from 25MHz reference
• Four 0.7V current mode differential HCSL output pairs
• I2C support with readback capabilities up to 400kHz
• Spread spectrum for EMI reduction

Applications

• PCI Express clock generation

Procurement Notes

Verify the specific suffix 'EGILF' versus 'CGILF' against official Renesas documentation, as datasheets often cite the EGILF variant. Confirm package type and pinout compatibility before procurement. Ensure the supplier provides traceability documents matching the manufacturer's specifications for this clock generator component.

Selection Notes

Select this component when a low-jitter 100MHz HCSL clock is required for PCI Express interfaces. Verify that the 25MHz reference input matches the system design, either via external source or internal crystal. Check if spread spectrum functionality is needed for EMI compliance, as this device supports configurable down-spread values via I2C.

Part Context

The 841S04 series belongs to Renesas' dedicated clock generator family optimized for high-speed digital interfaces. These devices utilize phase-locked loop technology to synthesize precise clock frequencies from lower-frequency references, ensuring signal integrity in demanding computing and communication applications.
