RENESAS 557GI03LFT PCI-Express Clock Generator
The ICS557-03 is a high-precision spread spectrum clock generator supporting PCI-Express Gen 1 and Ethernet standards. It reduces electromagnetic interference by providing two differential (HCSL) spread spectrum outputs with configurable spread types and amounts, utilizing advanced PLL techniques. The device operates at 3.3 V, with an input frequency of 25 MHz, and can generate outputs at 25, 100, 125, or 200 MHz for HCSL and 25 or 100 MHz for LVDS, making it suitable for PC and embedded systems requiring accurate, low-jitter clock signals.
