Spread Spectrum Desktop/Notebook System Frequency Generator

Features

Key Specifications

• Maximized EMI suppression using Cypress’s Spread

Spectrum technology

Supply Voltages:....................................... V_DDQ3= 3.3V±±5

...............................................................................................

V_DDQ2= 2.±V±±5

• Reduces measured EMI by as much as 10 dB

• I²C programmable to 153 MHz (16 selectable

frequencies)

CPU Cycle to Cycle Jitter: .......................................... 200 ps

CPU, PCI Output Edge Rate:ꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀꢀt1 V/ns

CPU0:1 Output Skew: ................................................ 17± ps

PCI_F, PCI1:6 Output Skew: ...................................... ±00 ps

CPU to PCI Skew: ..............................1 to 4 ns (CPU Leads)

REF2X/SEL48#, SCLOCK, SDATA ................2±0-k: pull-up

• Two skew-controlled copies of CPU output

• SEL100/66# selects CPU frequency (100 or 66.8 MHz)

• Seven copies of PCI output (synchronous w/CPU

output)

• One copy of 14.31818-MHz IOAPIC output

• One copy of 48-MHz USB output

Note: Internal pull-up resistors should not be relied upon for

setting I/O pins HIGH.

• Selectable 24-/48-MHz output is determined by resistor

straps on power-up

PCI

• One high-drive output buffer that produces a copy of

the 14.318-MHz reference

33.3 MHz

33.4 MHz

• Isolated core VDD pin for noise reduction
