The IDT8V49N231I is a high-performance PLL-based clock generator designed to interface with Broadcom XLP2xxx processors. The IDT8V49N231I 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 IDT8V49N231I low jitter VCO easily meets PCI Express Gen 1, 2 and 3 requirements.
Excellent phase noise performance is maintained with IDT’s Fourth Generation FemtoClock® NG technology.
