Resets the transceiver PLL. The pll_areset signal is asserted in two conditions:
■
■
Powers down the entire transceiver block. When this signal is asserted, this signal powers
down the PCS and PMA in all the transceiver channels.
This signal operates independently from the other reset signals. This signal is common to
the transceiver block.
A status signal. Indicates the status of the transmitter multipurpose PLLs or general
purpose PLLs.

During reset sequence, the signal is asserted to reset the transceiver PLL. This signal is
controlled by the user.
After the transceiver PLL is reconfigured, the signal is asserted high by the
ALTPLL_RECONFIG controller. This signal is not controlled by the user.
A high level—indicates the multipurpose PLL or general purpose PLL is locked to the
incoming reference clock frequency.
