EP1M350 devices have 18 individual transmitter channels. EP1M120 devices have 8 individual transmitter
channels.
W = 1 to 12, 14, 16, 18, or 20
B = 1 to 12, 14, 16, 18, or 20
J = 4, 7, 8, 9 to 12, 14, 16, 18, or 20
W, B, and J do not have to be equal.
This clock pin drives an HSDI PLL only. It does not drive to the logic array.

The Mercury device’s source-synchronous mode also supports the
RapidIO interface protocol at up to 500 Mbps using the LVDS I/O
standard.
