This chapter describes the procedure for merging; for example, when combining
multiple protocols and data rates within a transceiver block. The instances you can
combine include Receiver Only and Transmitter and Receiver channels as well as
channels configured in Protocol Functional modes, channels using PLL cascade
clocks, channels in multiple transceiver blocks, and channels with a Basic (PMA
Direct) configuration. This chapter also offers several examples of sharing the clock
multiplier unit phase-locked loops (CMU PLLs).
For information about the supported data rate range for the auxiliary transmit
(ATX) PLL, refer to the “Transceiver Performance Specifications” section in the
and Switching Characteristics for Stratix IV Devices
Each transceiver channel in a Stratix
data rate or in an independent protocol mode. Within each transceiver channel, the
transmitter and receiver channels can run at different data rates. Each transceiver
block consists of two CMU PLLs that provide clocks to all the transmitter channels
within the transceiver block. Each receiver channel contains a dedicated clock data
recovery (CDR) unit.
In addition to the CMU PLLs, the ATX PLLs are available to provide clocks to the
transmitter channels that are configured for a specific data rate range.
