CLK_STPB - Assertion (transition from logic “0” to logic “1”)
When this asynchronous input is pulled low, all clocks (CPUT/C, DDRT/C, PCI) are pulled low with a two
cycle latency. See waveform 3. This condition assumes all CPUT/C, DDRT/C, and PCI clocks are enabled
via Byte 3 (Bit 5, Bit 6), Byte 3 (Bit 0, 1, 2, 3, 5, 6, 7). The set up time is 10 ns.
CLK_STPB - Deassertion (transition from logic “1” to logic “0”)
When this asynchronous input is pulled high, all clocks (CPUT/C, DDRT/C, PCI) are enabled after a setup
time of 10 ns and two cycle latency. See waveform 3. The waveform assumes that the CPUT/C, DDRT/C,
and PCI clocks are enabled via Byte 1 (Bit 5, Bit 6), Byte 3 (Bit 0, 1, 2, 3, 5, 6, 7). The set up time is 10 ns.
IREF
If board target trace impedance (Z) is 50
, then Rr = 475 (1%), providing IREF of 2.32 mA, output current (I
OH) is
equal to 6*IREF.
