4.7. Combining Status or PLL Lock Signals with User Coded Reset Controller

You can combine multiple PHY status signals before feeding into the reset controller as shown below.
Figure 182. Combining Multiple PHY Status Signals
Note: This configuration also applies to the rx_cal_busy signals.

When using multiple PLLs, you can logical AND the pll_locked signals feeding the reset controller. Similarly, you can logical OR the pll_cal_busy signals to the reset controller tx_cal_busy port as shown below.

Figure 183. Multiple PLL Configuration

Resetting different channels separately requires multiple reset controllers. For example, a group of channels configured for Interlaken requires a separate reset controller from another group of channels that are configured for optical communication.
