W83195BR-S Description
The W83195BR-S is a Clock Synthesizer for Intel 815 Solano chipset. W83195BR-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. All clocks are externally selectable with smooth transitions.
W83195BR-S Key Features
- 2 CPU clocks
- 3 3V66 for chipset and AGP clocks
- 12 SDRAM clocks for 3 DIMMs
- 8 PCI synchronous clocks
- Optional single or mixed supply: (VddR = VddP=VddS = Vdd48 = Vdd3 = 3.3V, VddLAPIC=VddLCPU=2.5V)
- Skew form CPU to PCI clock -1 to 4 ns, center 2.6 ns
- Smooth frequency switch with selections from 66.8 to 200 MHz 2 2
- I C 2-Wire serial interface and I C read back
- 0.25% and 0.5% center type spread spectrum
- Programmable registers to enable/stop each output and select modes (mode as Tri-state or Normal )
