Description
The W83115RG-965 is a CK505 Clock Synthesizer for Intel chipsets. The W83115RG-965 provides all clocks
required for the high-speed microprocessor and provides step-less frequency programming and 32 different
frequencies of CPU, PCI, and SRC clocks setting. The W83115RG-965 also supports SATA and DOT clock
outputs. All clocks are externally selectable with smooth transitions.
The W83115RG-965 provides I2C serial bus interface to program the registers to enable or disable each clock
output and provides -0.5% down type spread spectrum or programmable S.S.T. scale to reduce EMI.
The W83115RG-965 accepts a 14.318 MHz reference crystal as its input and runs on a 3.3V supply.
Features
2 pairs of push-pull Differential clock outputs for CPU, 1 free running.
7 pairs of push-pull Differential clock outputs for SRC.
