Notes to Table 1–34:
(1) Cyclone IV E—true LVDS transmitter is only supported at the output pin of Row I/O Banks 1, 2, 5, and 6.
Cyclone IV GX—true LVDS transmitter is only supported at the output pin of Row I/O Banks 5 and 6.
(2) t
LOCK
is the time required for the PLL to lock from the end-of-device configuration.
(3) Cyclone IV E 1.0 V core voltage devices only support C8L, C9L, and I8L speed grades. Cyclone IV E 1.2 V core voltage devices only support
C6, C7, C8, I7, and A7 speed grades. Cyclone IV GX devices only support C6, C7, C8, and I7 speed grades.
