DRIVER/BUFFER
INDUSTRIAL TEMPERATURE RANGE
QS532807
FEATURES:
− JEDEC compatible LVTTL level
− 10 low skew clock outputs
− Clock input is 5V tolerant
− Pinout and function compatible with QS5807
− 25Ω on-chip resistors available for low noise
− Input hysteresis for better noise margin
− Guaranteed low skew:
• 0.35ns output skew (same bank)
• 0.6ns output skew (different bank)
• 0.75ns part-to-part skew
− Available in QSOP and SOIC packages
DESCRIPTION:
The QS532807 clock driver/buffer circuit can be used for clock
buffering schemes where low skew is a key parameter. The QS532807
offers ten non-inverting outputs. Designed in IDT's proprietary QCMOS
process, these devices provide low propagation delay buffering with on-
chip skew of 0.35ns for same-transition, same bank signals. The
QS532807 has on-chip series termination resistors for lower noise clock
signals. The QS532807 series resistor version is 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 systems. Several devices can be used in parallel
or scattered throughout a system for guaranteed low skew, system-wide
clock distribution networks.
