Block Diagram
Recommended Application:
CK-408 clock for Almador-M and Brookdale-Mobile
chipsets. Programmable for group to group skew.
Output Features:
3 Differential CPU Clock Pairs (differential current
mode)
7 PCI (3.3V) @ 33.3MHz
3 PCI_F (3.3V) @ 33.3MHz
1 USB (3.3V) @ 48MHz
1 DOT (3.3V) @ 48MHz
1 REF (3.3V) @ 14.318MHz
1 3V66 (3.3V) @ 66.6MHz
1 VCH/3V66 (3.3V) @ 48MHz or 66.6MHz
3 66MHz_OUT/3V66 (3.3V) @ 66.6MHz_IN
or 66.6MHz
1 66MHz_IN/3V66 (3.3V) @ Input/66MHz
Features:
Almador Chipset has a DLL driving the clock buffer
path for the 3 buffer path 66.6 MHz outputs,
66Buf(0:2).
Almador board level designs MUST
use pin 22, 66Buf_1, as the feedback connection
from the clock buffer path to the Almador
(GMCH) chipset.
Supports spread spectrum modulation,
down spread 0 to -0.5%.
Efficient power management scheme through PD#,
CPU_STOP# and PCI_STOP#.
Key Specifications:
CPU Output Jitter <150ps
3V66 Output Jitter <250ps
66MHz Output Jitter (Buffered Mode Only) <100ps
CPU Output Skew <100ps
