W83194BR-730
1. GENERAL DESCRIPTION
The W83194BR-730 is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessor such as AMD K7. W83194BR-730 provides 64 CPU/PCI frequencies which are selectable with smooth transitions by hardware or software. W83194BR-730 also provides 13 SDRAM clocks. The W83194BR-730 provides step-less frequency programming by controlling the VCO freq. and the programmable PCI clock output divisor ratio. A watch dog timer is quipped and when time out, the RESET# pin will output 4ms pulse signal. The W83194BR-730 accepts a 14.318 MHz reference crystal as its input. Spread spectrum built in at 0~-0.5% or 0.25% to reduce EMI. Programmable stopping individual clock outputs and frequency selection through I2C interface. The device meets the Pentium power-up stabilization, which requires CPU and PCI clocks be stable within 2 ms after power-up. Using dual function pin for the slots(ISA, PCI, CPU, DIMM) is not recommend.

The Pin column lists the affected pin number and the @PowerUp column gives the default state at true power up. "Command Code" byte and "Byte Count" byte must be sent following the acknowledge of the Address Byte. Although the data (bits) in these two bytes are considered "don't care", they must be sent and will be acknowledge. After that, the sequence described below (Register 0, Register 1, Register 2, ....) will be valid and acknowledged. Bytes sequence order for I2C controller :
Clock Address A(6:0) & R/W
Ack
8 bits dummy Command code
Ack
8 bits dummy Byte count
