Chapter 1: HardCopy IV GX Transceiver Architecture
Functional Modes
After offset cancellation is complete, your divider settings are restored. Then the
reconfiguration block sends and receives data to the ALTGX using the
reconfig_togxb and reconfig_fromgxb buses. Connect the buses between the
ALTGX_RECONFIG and ALTGX instances. The de-assertion of the busy signal from
the offset cancellation control logic indicates the offset cancellation process is
complete.
Functional Modes
You can configure HardCopy IV GX transceivers in one of the following functional
modes using the ALTGX MegaWizard Plug-In Manager:
■ Basic
■ Basic single-width at 600 Mbps to 3.75 Gbps
■ Basic double-width at 1 Gbps to 6.5 Gbps
■ PCI Express (PIPE) (Gen1 at 2.5 Gbps and Gen2 at 5 Gbps)
■ XAUI (3.125 Gbps up to HiGig at 3.75 Gbps)
■ GIGE (1.25 Gbps)
■ Serial RapidIO (1.25 Gbps, 2.5 Gbps, and 3.125 Gbps)
■ SONET/SDH (OC-12 and OC-48)
■ (OIF) CEI PHY Interface (>3.135 Gbps to 6.375 Gbps)
■ SDI (HD at 1.485/1.4835 Gbps and 3G at 2.97/2.967 Gbps)
Basic Functional Mode
The HardCopy IV GX transceiver datapath is extremely flexible in Basic functional
mode. To configure the transceiver in Basic functional mode, you must select Basic in
the Which protocol will you be using? option of the ALTGX MegaWizard Plug-In
Manager.
Basic functional mode can be further sub-divided into the following two functional
modes:
■ Basic single-width mode
■ Basic double-width mode
You can configure the transceiver in Basic single-width mode by selecting Single in
the What is the deserializer block width? option in the ALTGX MegaWizard Plug-In
Manager. You can configure the transceiver in Basic double-width mode by selecting
Double in the What is the deserializer block width? option in the ALTGX
MegaWizard Plug-In Manager.
