W196 - Spread Spectrum FTG

General Description

CPU Clock Outputs 0 through 1: These two CPU clocks run at a frequency set by FS0:1 or the serial data interface.

See Table 1 and Table 5.

Output voltage swing is set by the voltage applied to VDDQ2.

Key Features

  • Maximized EMI suppression using Cypress’s Spread Spectrum Technology www. DataSheet4U. com.
  • System frequency synthesizer for 440BX, 440ZX, and VDDQ2 = 2.5V±5% CPU Cycle to Cycle Jitter: 250 ps CPU, PCI Output Edge Rate: t1 V/ns CPU0:1 Output Skew: 175 ps PCI_F, PCI1:6 Output Skew: 500 ps CPU to PCI Skew: 1.5 to 4.0 ns (CPU Leads) REF2X/SEL48#, SCLOCK, SDATA: 250-k: pull-up FS1: 250-k: pull-down FS0: No pull-up or pull-down Note: In.
