CY2030

The CY2030 is a peripheral clock generator for most motherboards using fifth and sixth generation processors. The device outputs two copies of a 48 MHz USB clock, as well as one copy of a 24 MHz I/O clock, both of which meet Intel's accuracy, drive, and jitter requirements. Additionally, the part drives two audio clock outputs at 2X and 1X frequencies respectively.

These audio clocks support all frequencies that are required by CODECs and FM synthesizers. Finally, the part outputs three reference clocks at 14.318 MHz, which can be used to drive ISA slots, graphics accelerators, and other devices requiring this frequency.

The CY2030 can be used with the CY2275-1 and CY2276-1 (which are CPU, AGP, PCI, and SDRAM clock generators) to provide a complete clock solution for PC motherboards.

The CY2030 accepts a 14.318 MHz reference signal as its input. The CY2030 has two PLLs, one of which generates the audio clocks, and the other generates the Universal Serial Bus (USB) and I/O clocks. The CY2030 runs off a 3.3V supply.
