SIU AC Characteristics
This table lists SIU input characteristics.
NOTE: CLKIN Jitter and Duty Cycle
The CLKIN input to the SoC should not exceed +/– 150 psec of jitter
(peak-to-peak). This represents total input jitter—the combination of short
term (cycle-to-cycle) and long term (cumulative). The duty cycle of CLKIN
should not exceed the ratio of 40:60. The rise/file time of CLKIN should
adhere to the typical SDRAM device AC clock requirement of 1 V/ns to
meet SDRAM AC specs.
NOTE: Spread Spectrum Clocking
Spread spectrum clocking is allowed with 1% input frequency down-spread
at maximum 60 KHz modulation rate regardless of input frequency.
NOTE: PCI AC Timing
The SoC meets the timing requirements of PCI Specification Revision 2.2.
See Section 7, “Clock Configuration Modes,” and “Note: Tval (Output
Hold)” to determine if a specific clock configuration is compliant.
