DESCRIPTION
The QS532806 clock driver/buffer circuit can be used for clock buffering
schemes where low skew is a key parameter. The QS532806 offers two
banks of five inverting outputs. Designed in IDT's proprietary CMOS
process, these devices provide low propagation delay buffering with on-
chip skew of 0.7ns for same-transition, same-bank signals.
The QS532806 has on-chip series termination resistors for lower noise
clock signals. The series resistor versions are recommended for driving
unterminated lines with capacitive loading and other noise sensitive clock
distribution circuits. These clock buffer products are designed for use in
high-performance workstations, embedded and personal computing sys-
tems. Several devices can be used in parallel or scattered throughout a
system for guaranteed low skew, system-wide clock distribution networks.
