QUICC Engine Block IEEE 1588 AC Specifications
The following table provides the QUICC Engine block IEEE 1588 AC timing specifications.
The following figure shows the data and command output AC timing diagram.
1QUICC Engine block IEEE 1588 Output AC timing: The output delay is counted starting at the rising
edge if tT11588CLKOUT is non-inverting. Otherwise, it is counted starting at the falling edge.

Notes:
1. TRX_CLK is the max clock period of the QUICC Engine block’s receiving clock selected by TMR_CTRL[CKSEL]. See the
QUICC Engine Block with Protocol Interworking Reference Manual, for a description of TMR_CTRL registers.
2. It needs to be at least two times the clock period of the clock selected by TMR_CTRL[CKSEL]. See the QUICC Engine Block
with Protocol Interworking Reference Manual, for a description of TMR_CTRL registers.
3. The maximum value of tT1588CLK is not only defined by the value of tRX_CLK, but also defined by the recovered clock. For
example, for 10/100/1000 Mbps modes, the maximum value of tT1588CLK are 2800, 280, and 56 ns, respectively.
4. The minimum value of tTX/RXCLK is defined by the recovered clock. For example, for 10/100/1000 Mbps modes, the value of
tTX/RXCLK are 800, 80, and 16 ns, respectively.
5. System/board must be designed to ensure the input requirement to the device is achieved. Proper device operation is
guaranteed for inputs meeting this requirement by design, simulation, characterization, or functional testing.
