Transceivers
Transmitter Path
© December 2009 Altera Corporation
Each transceiver channel is full-duplex and consists of a transmitter channel and a
receiver channel.
The transmitter channel contains the following sub-blocks:
■
■
■
■
■
The receiver channel contains the following:
■
■
■
■
■
■

You can configure the transceiver channels to the desired functional modes using the
ALT2GXB MegaCore instance in the Quartus
the Arria GX device family. Depending on the selected functional mode, the
Quartus II software automatically configures the transceiver channels to employ a
subset of the sub-blocks listed above.
This section describes the data path through the Arria GX transmitter. The sub-blocks
are described in order from the PLD-transmitter parallel interface to the serial
transmitter buffer.
Clock Multiplier Unit
Each transceiver block has a clock multiplier unit (CMU) that takes in a reference
clock and synthesizes two clocks: a high-speed serial clock to serialize the data and a
low-speed parallel clock to clock the transmitter digital logic (PCS).
The CMU is further divided into three sub-blocks:
■

■
Transmitter phase compensation first-in first-out (FIFO) buffer
Byte serializer (optional)
8B/10B encoder (optional)
Serializer (parallel-to-serial converter)
Transmitter differential output buffer
Receiver differential input buffer
Receiver lock detector and run length checker
CRU
Deserializer
Pattern detector
Word aligner
Lane deskew
Rate matcher (optional)
8B/10B decoder (optional)
Byte deserializer (optional)
Receiver phase compensation FIFO buffer
One transmitter PLL
One central clock divider block
Four local clock divider blocks (one per channel)
