Intelâ„¢ Mobile/SDRAM Clock Source

The MK1492-03 is a low cost, low jitter, high performance Clock Synthesizer for Intels 430TX and 440BX chipsets for Pentium and Pentium II Processor based computer applications. Using patented Analog Phase-Locked Loop (PLL) techniques, the device accepts a 14.318 MHz crystal input to produce multiple output Clocks up to 75 MHz. It provides selectable Host and Host/2 PCI local bus Clocks and a selectable 24/48 MHz Clock for Super I/O or Universal Serial Bus (USB). The device has up to eight Host output Clocks and includes a serial port for controlling the output Clocks The chip has three different power down modes to reduce power consumption. I2C Serial Port for ACPI support Packaged in 28 pin, 150 mil wide SSOP Provides all critical Timing for Intel mobile chipsets Separate VDD and auto adjust for Host 1,2 supports 3.3 V or 2.5V processors 48MHz USB or 24MHz SIO support Single pin CPU(Host) slowdown to 33.3MHz option Multiple power down modes Low EMI Enable pin reduces EMI radiation on HOST and PCI Clocks (patented) Selectable PCIF on up to 3 outputs Support for AC97 Audio Clocks By Integrated Device Technology
