Notes
28.Since this timing parameter is greater than the minimum time period of REFCLK it sets an upper limit to the frequency in which REFCLKx can be used to clock
the receive data out of the output register. For predictable timing, users can use this parameter only if REFCLK period is greater than sum of t
and set-up
time of the upstream device. When this condition is not true, RXCLKx± (a buffered or divided version of REFCLK when RXCKSELx = 1) could be used to clock
the receive data out of the device.
29.Measured using a 50% duty cycle reference clock.
30.REFCLKx has no phase or frequency relationship with the recovered clock and only acts as a centering reference to reduce clock synchronization time. REFCLKx
must be within ±1500 ppm (±0.15%) of the remote transmitter’s PLL reference (REFCLKx) frequency. Although transmitting to a HOTLink II receiver channel
necessitates the frequency difference between the transmitter and receiver reference clocks to be within ±1500 ppm, the stability of the crystal needs to be
within the limits specified by the appropriate standard when transmitting to a remote receiver that is compliant to that standard. For example, to be IEEE 802.3z
Gigabit Ethernet compliant, the frequency stability of the crystal needs to be within ±100 ppm.l.
