15 GHz Buffer/Multiplier/Divider with SYSREF (JESD204B/C support) and FPGA Clock

The

LMX1404-EP is an buffer, divider and

multiplier that features high frequency, ultra-low jitter, and SYSREF outputs. This

device combined with an ultra-low noise reference clock source is an exemplary

design for clocking data converters, especially when sampling above 3GHz. Each of

the 4 high frequency clock outputs and additional LOGICLK output is paired with a

SYSREF output clock signal. The SYSREF signal for JESD interfaces can either be

internally generated or passed in as an input and re-clocked to the device clocks.

This device can distribute the multichannel, low skew, ultra-low noise local

oscillator signals to multiple mixers by disabling the SYSREF outputs.
