W83194BR-S  
200MHZ 2-DIMM CLOCK FOR SOLANO CHIPSET  
1.0 GENERAL DESCRIPTION  
The W83194BR-S is a Clock Synthesizer for Intel 815 Solano chipset.  
W83194BR-S provides all  
clocks required for high-speed RISC or CISC microprocessor and also provides 64 different  
frequencies of CPU, SDRAM, PCI, 3V66, IOAPIC clocks frequency setting.  
selectable with smooth transitions.  
All clocks are externally  
The W83194BR-S provides I2C serial bus interface to program the registers to enable or disable each  
clock outputs and provides 0.25% and 0.5% center type spread spectrum to reduce EMI.  
The W83194BR-S provides stepless frequency programming by controlling the VCO freq. and the  
clock output divisor ratio.  
Also the skew of CPU, SDRAM and 3V66 clock outputs are  
programmable. A watch dog timer is quipped and when time out, the RESET# pin will output 4ms pulse  
signal.  
The W83194BR-S accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply.  
High drive PCI and SDRAM 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, 24MHz, and 48 MHz provide  
better than 0.5V /ns slew rate.
