DESCRIPTION The PLL702-01 is a low cost, low jitter, and high performance clock synthesizer for generic PowerPC based applications. It provides one CPU clock, three ASIC outputs, one PCI output, and a selectable 48, 30 or 12MHz (USB) output. The user can choose between 9 different CPU clock frequencies, while the ASIC output can be identical or half of the CPU frequency. Low EMI Spread Spectrum Technology is available for the CPU, ASIC and PCI clocks. The CPU drive strength is user selectable from low cost 14.31818MHz crystal. The CPU and ASIC clock can be driven from an independent 2.5V power supply.
