A family of 28 buffers offers six fanout combinations, supports
clock rates up to 750 MHz, and a wide range of input and
output clock signals making it ideal to use across multiple
applications with minimal design efforts.
Internal input termination eliminates the need for external
termination and biasing components. In addition, the ultra low-
additive jitter and highly effective power supply noise filtering
leaves the majority of the jitter budget to the clock source.
The clock buffers devices are synergistic with Microsemi
®
industry-leading timing portfolio and, when used together,
these devices provide customer improved board performance
and complete timing solutions.
Available and Support
Clock Distribution Clock Buffers are in volume production.
