DESCRIPTION:
The 5T90533 2.5V single data rate (SDR) clock buffer is a user-select-
able single-ended or differential input to five single-ended outputs buffer
built on advanced metal CMOS technology. The SDR clock buffer fanout
from a single or differential input to five single-ended outputs reduces the
loading on the preceding driver and provides an efficient clock distribution
network. The 5T90533 can act as a translator from a differential HSTL,
eHSTL, 1.8V/2.5V LVTTL, LVEPECL, or single-ended 1.8V/2.5V LVTTL
input to HSTL, eHSTL, 1.8V/2.5V LVTTL outputs. Selectable interface is
controlled by 3-level input signals that may be hard-wired to appropriate
high-mid-low levels. Multiple power and grounds reduce noise.
APPLICATIONS:
• Clock and signal distribution
