DATA SHEET
General Description
The 8V49N211 is a high-performance PLL-based clock generator designed to interface with Broadcom XLP2xxx processors. The 8V49N211 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 8V49N211 low jitter VCO easily meets PCI Express Gen 1, 2 and 3 requirements.
IDT’s Fourth Generation FemtoClock® NG technology has best in class phase noise performance.
Features
Fourth Generation FemtoClock® NG PLL technology Two LVCMOS clock outputs for core/DDR3 at 133.33MHz or
66.66MHz
One LVDS clock output for USB at 100MHz Three LVDS clock outputs for SGMII/XAUI at 125MHz Five HCSL clock outputs for PCIe at 100MHz Crystal oscillator interface designed for 25MHz (CL = 12pF)
