General Description
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.

FEATUREs
• 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%, 0 to 70°C
• All outputs (0:15) tristate with OE low (FB_OUT stays running).
• 48-Pin SSOP package
