Stratix GX Device Handbook, Volume 1
The Stratix GX device family supports high-speed serial transceiver
blocks with CDR circuitry as well as source-synchronous interfaces. The
channels on the right side of the device use an embedded circuit
dedicated for receiving and transmitting high-speed serial data streams
to and from the system board. These channels are clustered in a
four-channel serial transceiver building block and deliver high-speed
bidirectional point-to-point data transmissions to provide up to
3.1875 Gbps of full-duplex data transmission per channel. The channels
on the left side of the device support source-synchronous data transfers
at up to 1 Gbps using LVDS, LVPECL, 3.3-V PCML, or HyperTransport
technology I/O standards.
The differential source-synchronous serial interface and the high-speed
serial interface are described in the Stratix GX Transceivers chapter of the
Stratix GX Device Handbook, Volume 1.
