Q4 VT0 Q4 CLK0 The ADCLK948 is an ultrafast clock fanout buffer fabricated
on the Analog Devices, Inc., proprietary XFCB3 silicon germanium
(SiGe) bipolar process. This device is designed for high speed
applications requiring low jitter.
The device has two selectable differential inputs via the IN_SEL …
