For the HSDI I/O band, half of the dedicated banks support LVDS, 3.3-V
PCML or LVPECL, and receiver inputs, while the other half support
LVDS, PCML or LVPECL, and transmitter outputs. A single device can
support 1.5-V, 1.8-V, 2.5-V, and 3.3-V interfaces; each bank can support a
V
level so that each bank can support any of the terminated standards (such
as SSTL-3) independently. A bank can support a single V

can be used as a regular I/O if a V

Each bank can support multiple standards with the same V
pins. For EP1M120 devices, each bank can support one voltage-referenced
I/O standard, but can support multiple I/O standards with the same

outputs.
EP1M350 devices, each bank can support two voltage-reverenced I/O
standards; each I/O bank is split into two voltage-referenced sub-banks.
When using the two HSDI transmitter banks as regular I/O banks in a
non-HSDI mode, those two banks require the same V
