Features, Applications

Pentium/II, 6x86, K6 Clock Synthesizer/Driver for Desktop PCs with Intel 82440LX or ALI IV/IV+, AGP and 3 DIMMs

Features

Mixed 2.5V and 3.3V operation Complete clock solution for Pentium, Pentium II, Cyrix, and AMD processor-based motherboards Four CPU clocks Up to twelve 3.3V SDRAM clocks Seven synchronous PCI clocks, one free-running One 3.3V 48-MHz USB clock One 2.5V IOAPIC clock (-3 option only) Two AGP clocks or 66.6 MHz (-2 option only) One 3.3V Ref. clock at 14.318 MHz SPI Serial Configuration Interface Factory-EPROM programmable output drive and slew rate for EMI customization Factory-EPROM programmable CPU clock frequencies for custom configurations Power-down, CPU stop and PCI stop pins Available in space-saving 48-pin SSOP package The CY2273A possesses power-down, CPU stop, and PCI stop pins for power management control. These inputs are multiplexed with SDRAM clock outputs, and are selected when the MODE pin is driven LOW. Additionally, the signals are synchronized on-chip, and ensure glitch-free transitions on the outputs. When the CPU_STOP input is asserted, the CPU clock outputs are driven LOW. When the PCI_STOP input is asserted, the PCI clock outputs (except the free-running PCI clock) are driven LOW. When the PWR_DWN pin is asserted, the reference oscillator and PLLs are shut down, and all outputs are driven LOW. The CY2273A outputs are designed for low EMI emissions. Controlled rise and fall times, unique output driver circuits and factory-EPROM programmable output drive and slew-rate enable optimal configurations for EMI control.


Clocks Outputs CPU MHz) CPU (60, 66.6 MHz) SDRAM PCI (30, 33.3 MHz) USB/IR (48 MHz) AGP or 66 MHz) IOAPIC (14.318 MHz) Ref (14.318 MHz) CPU-PCI delay


The is a clock synthesizer/driver for a Pentium, Pentium II, Cyrix, or AMD processor-based PC using Intel's 82430TX, 82440LX, ALI Aladdin IV or Aladdin IV+ chipsets. The CY2273A-1 outputs four CPU clocks or 3.3V with to 83.3MHz operation. There are seven PCI clocks, running at 30 and 33.3MHz. One of the PCI clocks is free-running. Additionally, the part outputs up to twelve 3.3V SDRAM clocks, one 3.3V USB clock at 48 MHz, and one 3.3V reference clock at 14.318 MHz. The CY2273A-2 is similar, except that PCICLK4 and PCICLK5 are now AGP clocks. The CY2273A-3 is more suited to Pentium II systems, as it outputs one 2.5V IOAPIC clock. Finally, the CY2273A-4 is similar to the CY2273A-1 except that is supports 0-ns CPU-PCI delay.
