Description

The 8V49N231I is a high-performance PLL-based clock generator designed to interface with Broadcom XLP2xxx processors. This device has one 25MHz crystal input to generate output frequencies to support XLP Core/DDR3, USB, SGMII/XAUI, and PCIe reference clocks in a single chip. The 8V49N231I low jitter VCO easily meets PCI Express Gen 1, 2, and 3 requirements.

Excellent phase noise performance is maintained with Renesas' Fourth-Generation FemtoClock® NG technology.
