W83194BR-B General Description

The W83194BR-B is a Clock Synthesizer for Intel Brook dale 845 chipset. W83194BR-B provides all clocks required for high-speed microprocessor and provides step-less frequency programming and 32 different frequencies of CPU, PCI, and 3V66 clocks setting. All clocks are externally selectable with smooth transitions.
T
he W83194BR-B provides I2C serial bus interface to program the registers to enable or disable each clock outputs and provides -0.5% and +/-0.25% center type spread spectrum or programmable S.S.T. scale to reduce EMI.
The W83194BR-B also has watch dog timer and reset output pin to support auto-reset when systems hanging caused by improper frequency setting.

The W83194BR-B accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply.

High drive PCI CLOCK outputs typically provide greater than 1 V /ns slew rate into 30 pF loads. CPU CLOCK outputs typically provide better than 1 V /ns slew rate into 20 pF loads as maintaining 50± 5% duty cycle. The fixed frequency outputs as REF and 48 MHz provide better than 0.5V /ns slew rate.

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).
