Zero Delay Buffers
9179-06 Rev F 6/22/99
Pin Configuration
The ICS9179-06 generates low skew clock buffers required
for high speed RISC or CISC microprocessor systems such as
Intel PentiumPro. An output enable is provided for testability.
The device is a buffer with low output to output skew. This is
a zero delay buffer device, using an internal PLL. This buffer
can be used for phase synchronization to a master clock. With
the wide PLL loop BW, this buffer is compatible to Spread
Spectrum input clocks from clock generator products such as
the ICS9148-27.
The individual clock outputs are addressable through I2C to be
enabled, or stopped in a low state for reduced EMI when the
lines are not needed. The device defaults to zero-delay mode,
but can be programmed with I2C for selectable delays -2.7,
+2.0, -0.7 ns (nominal target values).
Zero delay buffer, 16 outputs
Supports up to four SDRAM DIMMS
Wide PLL loop bandwidth makes this part ideal in
Spread Spectrum applications.
Skew Input to FB_IN ±250ps default, with selectable
skew -2.7, +2.0, -0.7ns nominal.
Synchronous clocks skew matched to 250ps window on
output.
33 to 133MHz input or output frequency.
I2C Serial Configuration interface to allow individual
clocks to be stopped, or selectable delays.
Multiple VDD, VSS pins for noise reduction
Slew rate 1.5V/ns into 30pF.
VDD=3.3±5%,0to70°C
All outputs (0:15) tristate with OE low
(FB_OUT stays running).
