IMISC670 Overview
Xin, Xout - These pins form an on-chip reference oscillator when connected to terminals of an external parallel resonant crystal (nominally 14.318 MHz). Xin may also serve as input for an externally generated reference signal. SEL - Standard frequency select input.
IMISC670 Key Features
- enable/disable each output pin
- mode as tri-state, test, or normal
- 24/48 MHz selections 1 IOAPIC clock for multiprocessor support. 48-pin SSOP package
- These pins form an on-chip reference oscillator when connected to terminals of an external parallel resonant crystal (no
- Standard frequency select input. It has internal pull-up. CPUCLK(0:3)
- Low skew (<250 pS) clock outputs for host frequencies such as CPU, Chipset, Cache. Vddq2 is the supply voltage for these
- Synchronous DRAM DIMs clocks. They are powered by Vddq3. SDRAM6/CPU_STOP#
- If MODE=1, this pin is a Synchronous DRAM DIMs clock output powered by Vddq3. If MODE=0, this pin is a CPU_STOP# input s
- If MODE=1, this pin is a Synchronous DRAM DIMs clock output powered by Vddq3. If MODE=0, this pin is a PCI_STOP# input s
- A low level on this pin causes pins 26, and 27 to be power management inputs PCI_STOP#, and CPU_STOP# respectly. A high
