The IDT9248-39 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro or Cyrix. Eight different reference frequency multiplying factors are externally selectable with smooth frequency transitions.

The IDT9250-10 is a single chip for Intel Pentium II. It provides all necessary clock signals for such a system.

932S401 is a main clock synthesizer for CK410-generation Intel server platforms. 932S401 is driven with a 14.318MHz crystal. It generates CPU outputs up to 400MHz and PCI-Express clocks at 100 or 200 MHz. The 48 MHz USB clock is an exact 48.000 MHz clock. The 932S401 generates all clocks with less the +/- 300 ppm error.

The IDT932S422 is a main clock synthesizer for CK410B+ generation Intel server platforms. The IDT932S422 is driven with a 14.318MHz crystal. It generates 5 CPU outputs up to 400MHz and 4 PCIe Gen2 PCI-Express clocks. The 48 MHz USB clock is an exact 48.000 MHz clock.

The 932S825 is a main clock synthesizer chip that all clocks required by Serverworks HT2400-based servers. An SMBus interface allows full control of the device.

The 932S890C is a main clock synthesizer chip for SR5690/SR5670 AMD Servers. An SMBus interface allows full control of the device.
