Features
Benefits
Mixed 2.5V and 3.3V Operation
Compliant to Intel CK133 (CY2210-3) & CK133W
(CY2210-2) synthesizer and driver specification
Multiple output clocks at different frequencies
—Four CPU clocks, up to 133 MHz
—Eight synchronous PCI clocks, 1 free-running
—Two CPU/2 clocks, at one-half the CPU frequency
—Four AGP clocks at 66 MHz
—Three synchronous APIC clocks, at 16.67 MHz
—One USB clock at 48 MHz
—Two reference clocks at 14.318 MHz
Spread Spectrum clocking
—32.5-kHz modulation frequency @ 133 MHz
—33.1-kHz modulation frequency @ 100 MHz
—EPROM programmable percentage of spreading.
Default is –0.6%, which is recommended by Intel
Power-down features
Three Select inputs
Low-skew and low-jitter outputs
OE and Test Mode support
56-pin SSOP package
Logic Block Diagram
Usable with Pentium
II and Pentium
III processors
Single-chip main motherboard clock generator
—Driven together, support 4 CPUs and a chipset
—Support for 4 PCI slots and chipset
—Drives up to two main memory clock generators, includ-
ing DRCG (CPUCLK/2)
—Support for multiple AGP slots
—Support multiprocessing systems
—Supports USB frequencies and I/O chip
Enables reduction of EMI in some systems
Supports mobile systems
Supports up to eight CPU clock frequencies
Meets tight system timing requirements at high frequency
Enables ATE and “bed of nails” testing
Widely available, standard package enables lower cost
