PLL52C64-06
Clock Generator with Zero Delay Output Buffers
FEATURES
PIN INFORMATION
n Generates 7 synchronous zero delay PCI bus clocks.
n Designed to work with PLL52C64-05 or PLL52C64-25
for EMI reduction.
n Less than 250ps propagation delay from BCLKIN to BCLK
output when equally loaded.
n Two 14.318Mz reference clocks
n Two 2.5V IOAPIC clocks for dual processors.
n One 24Mhz and one 48Mhz USB clock
n All outputs have very low Cycle to cycle jitter (<150ps)
n < 250ps output skew between PCI bus clock
n < 250ps output skew between IOAPIC clock
n 50% duty cycle outputs.
n Available in 300mil 24 pin SOP.
DESCRIPTION
The PLL52C64-06 is a high performance clock generator designed specifically to support the very tight timing requirement
of Pentium PC Motherboards. All output clocks skew and jitter performance are designed to be fully compliant with INTEL
Pentium CPU timing requirements. This device associates with PLL52C64-05/-25 is the solution for the very stringent EMI
specifications when applied to PC Motherboards with up to 4 DIMM SDRAM.
