The LMK03806 device is a high-performance, ultra low-jitter, multi-rate clock generator capable of synthesizing 8 different frequencies on 14 outputs at frequencies of up to 2.6 GHz. Each output clock is programmable in LVDS, LVPECL or LVCMOS format. The LMK03806 integrates a high-performance integer-N PLL, low-noise VCO, and programmable output dividers to generate multiple reference clocks for SONET, Ethernet, Fiber Channel, XAUI, Backplane, PCIe, SATA, and Network Processors from a low-cost crystal.
