4.4. Using the Transceiver PHY Reset Controller
Transceiver PHY Reset Controller is a configurable IP core that resets transceivers
mainly in response to PLL lock activity. You can use this IP core rather than creating
your own user-coded reset controller. You can define a custom reset sequence for the
IP core. You can also modify the IP cores's generated clear text Verilog HDL file to
implement custom reset logic.
The Transceiver PHY Reset Controller handles all transceiver reset sequencing and
supports the following options:
• Separate or shared reset controls per channel in response to PLL lock activity
• Separate controls for the TX and RX channels and PLLs
• Synchronization of the reset inputs
• Hysteresis for PLL locked status inputs
• Configurable reset timing
• Automatic or manual reset recovery mode in response to loss of PLL lock
You should create your own reset controller if the Transceiver PHY Reset Controller IP
does not meet your requirements, especially when you require independent
transceiver channel reset. The following figure illustrates the typical use of the
Transceiver PHY Reset Controller in a design that includes a transceiver PHY instance
and the transmit PLL.
