Description
The W83194R-67A is a Clock Synthesizer which provides all clocks required for high-speed RISC or CISC microprocessors such as Intel Pentium, AMD, and Cyrix. It offers sixteen CPU/PCI frequencies that can be externally selected with smooth transitions. Additionally, the W83194R-67AA provides 13 SDRAM clocks controlled by the none-delay buffer_in pin.
Specifications and features
- Supports PentiumÔ, AMD, and Cyrix CPU with I2C.
- 4 CPU clocks (one free-running CPU clock).
- 13 SDRAM clocks for 3 DIMs.
- 6 PCI synchronous clocks.
- Optional single or mixed supply: (Vddq1=Vddq2 = Vddq3 = Vddq4 = VddL1 = VddL2 = 3.3V) or (Vddq1 = Vddq2 = Vddq3 = Vddq4 = 3.3V, VddL1 = VdqL2 = 2.5V).
- < 250ps skew among CPU and SDRAM clocks.
- < 4ns propagation delay SDRAM from buffer input.
- Skew from CPU(earlier) to PCI clock -1 to 4ns, center 2.6ns.
- Smooth frequency switch with selections from 60 MHz to 124 MHz CPU.
- I2C 2-Wire serial interface and I2C read back.
- ±0.25% or ±0.5% spread spectrum function to reduce EMI.
- Programmable registers to enable/stop each output and select modes (mode as Tri-state or Normal).
- 2ms power up clock stable time.
- MODE pin for power Management.
- One 48 MHz for USB & one 24 MHz for super I/O.
- 48-pin SSOP package.
