DESCRIPTION
The QS532805 clock buffer/driver circuits can be used for clock buffering
schemes where low skew is a key parameter. This device offers two banks
of 5 non-inverting outputs. The QS532805 incorporates 25series
termination resistors. This clock buffer product is designed for use in high
performance workstations, embedded and personal computing systems
using 3V to 3.6V supply voltages. Several can be used in parallel or
scattered throughout a system for guaranteed low skew, system-wide clock
distribution networks. The QS532805 can accept 5V input and control
signals.
The QS532805 is characterized for operation at -40°C to +85°C.
