Description
The MK1491-14 is a low cost, low jitter, high performance clock synthesizer for OPTi’s Firestar and Firestar+ chipsets for Pentium? Processor-based mobile computer applications. Using analog Phase-Locked Loop (PLL) techniques, the device uses a 14.318 MHz crystal input to produce multiple output clocks up to 75 MHz. It provides selectable Host and PCI local bus clocks as well as selectable clocks for Super I/O or Universal Serial Bus (USB). The device has up to seven Host output clocks.
Features
? Packaged in 28 pin, 150 mil wide SSOP
? Provides all critical timing for OPTi ACPI Firestar and Firestar+
? Early Host clock of 3.5ns
? Separate VDD and skew adjust for Host 5,6, and 7 supports field upgrade to Firestar+ and new 2.5V processors
? 48MHz USB, 24MHz SIO, and Audio clock support
? Single pin CPU(Host) slowdown to 33.3MHz
? Multiple power down modes
? Low EMI Enable pin reduces EMI radiation (patent pending)
