Integrated Circuit Systems AV9108
The AV9108 offers a tiny footprint solution for generating two simultaneous clocks. The other clock, CLK1, can vary between 2 and 120 MHz, with up to 16 selectable preprogrammed frequencies stored in internal ROM. The ICS9108 is ideal for use in a 3.3V system.| Part No. | AV9108 |

GENERAL DESCRIPTION
One clock, the REFCLK, is a fixed output frequency which is the same as the input reference crystal (or clock). The ICS9108 is ideal for use in a 3.3V system. It can generate a 66.66 MHz clock at 3.3V. In addition, the ICS9108 provides a symmetrical wave form with a worst case duty cycle of 45/55. The ICS9108 has very tight edge control between the CPU clock and 2XCPU clock outputs, with a worst case skew of 250ps. The device has advanced features which include on-chip loop filters, tristate outputs, and power-down capability. A minimum of external components - two decoupling capacitors and an optional ferrite bead - are all that are required for jitter-free operation. Standard versions for computer motherboard applications are the AV9108-03, AV9108-05 and the ICS9108-10. Custom masked versions, with customized frequencies and features, are available in 6-8 weeks for a small NRE fee.FEATURES
