Texas Instruments LMK03806 Ultra Low Jitter Clock Generator
Texas Instruments LMK03806 Ultra Low Jitter Clock Generator is capable of synthesizing 8 different frequencies on 14 outputs at frequencies of up to 2.6GHz. Each output clock is programmable in LVDS, LVPECL, or LVCMOS format. National Products from TI LMK03806 Ultra Low Jitter Clock Generator 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 crystal. NSC LMK03806 is ideal for use in ultra high-speed series interfaces in SONET/SDH as well as multi-gigabit Ethernet and fiber channel line cards.
