SMII_CLK
Timing was designed for a system load between 5pF and 25pF
Timing was designed for a system load between 5pF and 15pF
Clock to output delay for SMII_TXD[4:0] and
SMII_SYNC with respect to rising edge of
SMII_CLK
SMII_TXD[4:0] and SMII_SYNC hold time after
SMII_CLK.
Rising edge of clock to signal output. Outputs
included in this timing are UTP_OP_SOC,
UTP_OP_FCO, UTP_IP_FCO,
UTP_OP_DATA[7:0], UTP_IP_ADDR[4:0] and
UTP_OP_ADDR[4:0].
Signal output hold time after the rising edge of
the clock. Outputs included in this timing are
UTP_OP_SOC, UTP_OP_FCO, UTP_IP_FCO,
UTP_OP_DATA[7:0], UTP_IP_ADDR[4:0] and
UTP_OP_ADDR[4:0].
