GENERAL DESCRIPTION The W83195BR/G-101 is a Clock Synthesizer for Intel P4 processors and Intel Grandsdale chipsets. W83195BR/G-101 provides all clocks required for high-speed microprocessor and provides step-less frequency programming, 32 different frequencies of CPU, PCI, SRC clocks setting. Simultaneously W83194BR-101 supports SRC_SATA 100MHz clock output for SATA and DOT 96MHz clock outputs for integrated graphic chipsets. All clocks are externally selectable with smooth transitions. PRODUCT FEATURES • 2 pair 0.7 V current mode Differential clock outputs for CPU • 6 pair 0.7V current mode Differential clock outputs for SRC and SRC_SATA. • 1 pair 0.7V current mode Differential 96MHz clock outputs for DOT. • 6 PCI clock outputs for PCI • 3 PCI clock free running outputs for PCI • 1 48 MHz clock output for USB. • 1 14.318MHz REF clock outputs. • Step-less frequency programming • I2C 2-Wire serial interface and support byte read/write and block read/write. • -0.5% down type spread spectrum in H/W and software select mode. • Programmable S.S.T. scale to reduce EMI in M/N mode. • Programmable registers to enable/stop each output. • Programmable clock outputs to control skew. • Watch Dog Timer output • 56 pin SSOP package
