841S01CGLFT

Overview

The 841S01CGLFT is a PLL-based clock generator manufactured by Renesas Electronics, designed for PCI Express clock generation applications. It generates a 100 MHz HCSL differential output from a 25 MHz reference input, which can be derived from an external source or an on-chip crystal oscillator. The device supports I2C configuration with readback capabilities up to 400 kHz and offers spread spectrum clocking for EMI reduction. It operates on a 3.3 V supply within a 0°C to 70°C temperature range and is housed in a TSSOP-16 package.

Feature Summary

• Generates 100 MHz HCSL differential output from 25 MHz reference
• I2C interface with readback support up to 400 kHz
• Spread spectrum capability for EMI reduction (-0.35% or -0.5%)
• Supports external reference or internal 25 MHz crystal oscillator

Applications

• PCI Express clock generation
• High-speed digital system timing
• EMI-sensitive circuit designs

Procurement Notes
