28-lead, 5 mm × 5 mm, LFCSP package, 25 mm2 The HMC6832 is an input selectable, 2:8 differential fanout
buffer designed for low noise clock distribution. The IN_SEL
control pin selects one of the two differential inputs. This input
is then buffered to all eight differential outputs. The low jitter
outputs of the HMC6832 lead to synchronized low noise
switching of downstream circuits, such as mixers, analog-todigital converters (ADCs)/digital-to-analog converters (DACs), …
