W83194R-81 - Brand New Winbond Electronics IC Chips
-
Description
The W83194R-81 is a Clock Synthesizer designed specifically for SiS chipsets. It provides all the necessary clocks for high-speed RISC or CISC microprocessors, including AMD, Cyrix, and Intel Pentium. Additionally, it offers 16 different frequencies for CPU clock frequency settings, with smooth transitions. The W83194R-81 also allows for synchronous or asynchronous frequency synchronization with SDRAM and CPU clocks.
Specifications and features
- Supports PentiumÔ, PentiumÔ Pro, AMD, and Cyrix CPUs with I2C.
- 3 CPU clocks
- 13 SDRAM clocks for 3 DIMMs
- 6 PCI synchronous clocks
- Optional single or mixed supply voltages: Vdd = Vddq4=Vddq3 = Vddq2b = 3.3V, Vddq2=2.5V or Vdd = Vddq4=Vddq3 = 3.3V, Vddq2=Vdq2b = 2.5V
- Skew from CPU to PCI clock ranges from -1 to 4 ns, with a center of 2.6 ns
- SDRAM frequency can be synchronous or asynchronous to CPU clocks
- Smooth frequency switch with selections from 66 to 133 MHz (including 90MHz)
- I2C 2-Wire serial interface with read back capability
- 0.25% and 0.5% center type spread spectrum to reduce EMI
- Programmable registers to enable/stop each output and select modes (Tri-state or Normal)
- MODE pin for power management
- 48 MHz for USB
- 24 MHz for super I/O
- 48-pin SSOP packageApplication Scenarios
The W83194R-81 Clock Synthesizer is particularly well-suited for systems using SiS chipsets and requiring precise clock synchronization for high-performance RISC or CISC microprocessors. It is compatible with various CPUs including PentiumÔ, PentiumÔ Pro, AMD, and Cyrix, making it versatile for a range of applications.
