Notes to Figure 4–17 :
(1) SONET protocol mode supports duplex, receiver-only, or transmitter-only operation modes.
(2) Valid numbers are 1 to Max Channels available on the device. The Quartus II software automatically assigns the
channels to a transceiver block unless input/output pin assignments are made to the channel’s HSSIO input and
output pins.
(3) 8 bits is single width and 16 bits is double width.
(4) Refer to the Stratix GX Analog Description chapter for more information.
(5) The rxdigitalreset port resets the digital blocks in the receiver channel. Each active receiver channel contains
its own digital reset. The txdigitalreset port resets the digital blocks of the transmitter channel. Each active
transmitter channel contains its own digital reset. The rxanalogreset port resets the receiver's analog circuits
including the receiver PLL. Each active receiver channel contains its own analog reset. The pll_areset port resets
the entire transceiver block (all receiver and transmitter digital and analog circuits including receiver and
transmitter PLLs). If you send the pllenable signal low, the entire transceiver block is held in reset conditions.
(6) The pll_locked active high signal indicates that the transmitter PLL is locked to the reference input clock.
