The LMX1906-SP 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.
