W83194BR-730 - 166MHZ CLOCK

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.

Features

  • Supports AMD CPU with I C. 3 CPU clocks (one free-running CPU clock) 13 SDRAM clocks for 3 DIMMs 6 PCI synchronous clocks 2 AGP clocks 2 REF clocks as 14.318MHz outputs < 250ps skew among CPU and SDRAM clocks < 250ps skew among PCI clocks Skew from CPU(earlier) to PCI clock 1 to 4ns, center 2.6ns. Smooth frequency swit.

W83194BR-730 166MHZ CLOCK FOR SIS CHIPSET 1.0 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.
