Table 60. OR3LP26B FPGA to PCI, and PCI to FPGA, Combinatorial Path Delays

OR3LP26B Commercial: VDD = 3.0 V to 3.6 V, 0 °C < TA < 70 °C; VDD2 = 2.38 V to 2.63 V, 0 °C < TA < 70 °C.

Notes:

The FPGA to PCI combinatorial path delays include the ASIC path delay and the output buffer delay under a 10 pF load. They do not include the

interbuf delay on the FPGA side.

The PCI to FPGA combinatorial path delays include the ASIC input buffer delay, and ASIC path delay entering the FPGA. They do not include

the interbuf delay on the FPGA side.

Table 61. OR3LP26B FPGA Side Interface Combinatorial Path Delay Signals

OR3LP26B Commercial: VDD = 3.0 V to 3.6 V, 0 °C < TA < 70 °C; VDD2 = 2.38 V to 2.63 V, 0 °C < TA < 70 °C.

Note: The combinatorial path parameters are measured from the input to the output (both on the FPGA side), excluding the interbufs, which

traverse the ASIC/FPGA boundary. The

ORCA Foundry Static Analysis Tool, Trace, accounts for clock skew and interbuf delays on the

clock and data paths.
