W83195BR-118

Stresses greater than those listed in this table may cause permanent damage to the device. Precautions should be taken to avoid application of any voltage higher than the maximum rated voltages to this circuit. Subjection to maximum conditions for extended periods may affect reliability.Unused inputs must always be tied to an appropriate logic voltage level (Ground or V_DD).

The W83195BR-118 is a Clock Synthesizer for Intel P4 processors and Intel Grandsdale chipsets. W83195BR-118 provides all clocks required for high-speed microprocessor and provides step-less frequency programming, 32 different frequencies of CPU, PCI, PCI-Express clocks setting.

Simultaneously W83195BR-118 supports SRC 100MHz for SATA and DOT 96MHz clock outputs for integrated graphic chipsets. All clocks are externally selectable with smooth transitions.

The W83195BR-118 programs the registers to enable or disable each clock outputs through I²C serial bus interface and
provides -0.5% down type spread spectrum or programmable spread spectrum scale to reduce EMI.

The W83195BR-118 also has watchdog timer and reset output pin to support auto-reset when systems hanging caused by improper frequency setting.

The W83195BR-118 is driven with a 14.318 MHz reference crystal and runs on a 3.3V supply.
