Figure 63 shows in greater detail an example of the UTOPIA bus connections when two MT90500 devices and
a secondary AAL5 SAR are used. Note that the receive UTOPIA bus is controlled by RXEN of the secondary
AAL5 SAR. If the secondary SAR is too slow, or configured badly, it will throttle-back the cells output by the
PHY device, and cause lost cells or increased CDV. (RXEN may also be tied low to allow full speed cell
reception.) The MT90500 allows the primary UTOPIA port transmit clock (PTXCLK) to be one of: the transmit
clock of the secondary SAR (STXCLK), the master clock (MCLK) divided by 2 or 4, or an external source. The
primary UTOPIA port receive clock (PRXCLK) is driven by the secondary SAR, or it is tied to PTXCLK if a
secondary SAR is not present. PRXCLK should not be too slow, or CDV may be increased.
