Figure 2–1. Reset Control and Power-Down Block
Each transceiver channel in the Cyclone IV GX device has individual reset signals to
reset its physical coding sublayer (PCS) and physical medium attachment (PMA). The
transceiver block also has a power-down signal that affects the multipurpose
phase-locked loops (PLLs), general purpose PLLs, and all the channels in the
transceiver block.
All reset and power-down signals are asynchronous.
