AV9107C-05CS08

Integrated Circuit Systems, Inc. AV9107C CPU Frequency Generator The AV9107C offers a tiny footprint solution for generating two simultaneous clocks. One clock, the REFCLK, is a fixed output frequency which is the same as the input reference crystal (or clock). The other clock, CLK1, can vary between 2 and 120 MHz, with up to 16 selectable preprogrammed frequencies stored in internal ROM (frequency range depends on design option). 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 AV9107C-03, and AV9107C-05. Custom masked versions, with customized frequencies and features, are available in 6-8 weeks for a small NRE.
