Renesas Electronics Corporation Clock/Timing - Application Specific 841S01CGLFT

The 841S01CGLFT is a PLL-based clock generator designed for PCI Express clock generation applications. It produces a 100MHz HCSL clock output from a 25MHz reference input, which can be sourced externally or via an on-chip crystal oscillator. The device features a spread spectrum clock output to reduce electromagnetic interference (EMI), with selectable down spread values of -0.35% or -0.5% controlled through an I²C bus interface. Key specifications include a maximum RMS period jitter of 3ps and a maximum cycle-to-cycle jitter of 35ps. The device operates at a supply voltage of 3.3V and is rated for an ambient temperature range of 0°C to 70°C. It is available in a lead-free 16-lead TSSOP package, making it suitable for various applications requiring precise clock timing.
