FEATURES
/Benefits:● Supports tight ppm accuracy clocks for Serial-ATA
● Supports spread spectrum modulation, 0 to -0.5% down spread and +/- 0.25% center spread
●
●
● Supports CPU clks up to 400MHz in test mode Uses external 14.318MHz crystal Supports undriven differential CPU, SRC pair in PD# and CPU_STOP# for power management. Key Specifications:
● CPU/SRC outputs cycle-cycle jitter < 125ps
● 3V66 outputs cycle-cycle jitter < 250ps
●
●
● PCI outputs cycle-cycle jitter < 250ps CPU outputs skew: < 100ps +/- 300ppm frequency accuracy on CPU & SRC clocks Pin Configuration Functionality USB/ FS2 DOT CPU SRC 3V66 PCI REF MHz B6b5 FS_A FS_B MHz MHz MHz MHz MHz 0 0 100.00 100/200 66.66 33.33 14.318 48.00 0 1 200.00 100/200 66.66 33.33 14.318 48.00 0 1 0 133.33 100/200 66.66 33.33 14.318 48.00 1 1 166.66 100/200 66.66 33.
