W215B Datasheet - Cypress Semiconductor

W215B Notebook PC system Frequency Generator

W215B CPU Outputs 0 through 3: These four CPU outputs are controlled by the CPU_STOP# control pin. Output voltage swing is controlled by voltage applied to VDDQ2. PCI Bus Outputs 0 through 5: These six PCI outputs are controlled by the PCI_STOP# control pin. Output voltage swing is controlled by v.

W215B Features

* Generates system clocks for CPU, IOAPIC, SDRAM, PCI, USB plus 14.318 MHz (REF0:1)

* MODE input pin selects optional power management input control pins (reconfigures pins 26 and 27)

* Two fixed outputs separately selectable as 24-MHz or 48-MHz (default = 48-MHz)

* V
