Product Description

The new PI6C49021 is a high integration clock generator intended for all kinds of embedded applications and networking application with PCIe interface. The device is the most cost effective way to generate multi-frequencies and multi-outputs clocks from a 25MHz crystal and reference clock. The device can generate 100MHz HCSL clock, single-ended clocks includes 24MHz, 25MHz, 50HMz, 125HMz, and low jitter 25MHz LVPECL clock.
