VQFN (RHA)-40-36 mm² 6 x 6

The high frequency capability, extremely low jitter and programmable clock input and output delay of this device, makes a great approach to clock high precision, high-frequency data converters without degradation of signal-to-noise ratio. Each of the four high frequency clock outputs and additional LOGICLK outputs with larger divider range, is paired with a SYSREF output clock signal. The SYSREF signal for JESD204B/C interfaces can either be internally generated or passed in as an input and re-clocked to the device clocks. The noiseless delay adjustment at input path of the high frequency clock input and individual clock output paths insures low skew clocks in multi-channel system. For data converter clocking application, having the jitter of the clock less than the aperture jitter of the data converter is important. In applications where more than four data converters need to be clocked, a variety of cascading architectures can be developed using multiple devices to distribute all the high frequency clocks and SYSREF signals required. This device, combined with an ultra-low noise reference clock source, is an exemplary choice for clocking data converters, especially when sampling above 3GHz.
