Product Specification
Notes:
1. This parameter indicates the total sampling error of Virtex-II DDR input registers across voltage, temperature, and process. The
Notes:
1. IFF = Input Flip-Flop
2. The timing values were measured using the fine-phase adjustment feature of the DCM.
3. The worst-case duty-cycle distortion and DCM jitter on CLK0 and CLK180 is included in these measurements.
Sampling Error at Receiver Pins
Data Input Set-Up and Hold Times Relative to a Forwarded
Clock Input Pin, Using DCM and Global Clock Buffer.
For situations where clock and data inputs conform to
different standards, adjust the setup and hold values
accordingly using the values shown in
Characteristics Standard Adjustments, page
No Delay
Global Clock and IFF with DCM
characterization methodology uses the DCM to capture the DDR input registers’ edges of operation. These measurements include:
- CLK0 and CLK180 DCM jitter
- Worst-case Duty-Cycle Distortion - T
- DCM accuracy (phase offset)
- DCM phase shift resolution.
These measurements do not include package or clock tree skew.
