Pin Configuration
The ICS9179B-01 generates SDRAM clock buffers
required for high speed RISC or CISC microprocessor
systems such as Intel PentiumPro or Pentium II. An
output enable is provided for testability.
The device is a buffer with low output to output skew.This
is a Fanout buffer device, not using an internal PLL. This
buffer can also be a feedback to an external PLL stage for
phase synchronization to a master clock.
The individual clock outputs are addressable through I
2C
to be enabled, or stopped in a low state for reduced EMI
when the lines are not needed.
High speed, low noise non-inverting (0:17) buffer for
SDRAM clock buffer applications.
Supports up to four SDRAM DIMMS
Synchronous clocks skew matched to 250 ps
window on SDRAM.
I
2C Serial Configuration interface to allow individual
clocks to be stopped.
Multiple VDD, VSS pins for noise reduction
Tri-state pin for testing
Custom configurations available
3.0V – 3.7V supply range
48-pin SSOP package
48-Pin SSOP
