W83194BR-KT - STEP-LESS 3-DIMM K7 CLOCK

Description

The W83194BR-KT is a Clock Synthesizer which provides all clocks required for AMD K7.

W83194BR-KT provides 64 CPU/PCI frequencies which are selectable with smooth transitions by hardware or software.

W83194BR-KT also provides 13 SDRAM clocks controlled by the none-delay buffer_in pin.

Features

  • Supports AMD CPU with I2C. 3 CPU clocks (one free-running chipset clock controlled by I2C) 13 SDRAM clocks for 3 DIMMs 6 PCI synchronous clocks Optional single or mixed supply: (Vddq2 =2.5V, Vddq3 =3.3V) < 250ps skew among CPU and SDRAM clocks < 250ps skew among PCI clocks < 5ns propagation delay SDRAM from buffer inpu.

W83194BR-KT STEP-LESS 3-DIMM K7 CLOCK 1.0 GENERAL DESCRIPTION The W83194BR-KT is a Clock Synthesizer which provides all clocks required for AMD K7. W83194BR-KT provides 64 CPU/PCI frequencies which are selectable with smooth transitions by hardware or software. W83194BR-KT also provides 13 SDRAM clocks controlled by the none-delay buffer_in pin. The W83194BR-KT provides step-less frequency programming by controlling the VCO freq. and the programmable PCI clock output divisor ratio. A watchdog timer is quipped and when time out, the RESET# pin will output 4ms pulse signal. The W83194BR-KT accepts a 14.318 MHz reference crystal as its input. Spread spectrum built in at ±0.5% or ±0.25% to reduce EMI.
