Notes to Table 1–31:
(1) Applicable for true RSDS and emulated RSDS_E_3R transmitter.
(2) Cyclone IV E devices—true RSDS transmitter is only supported at the output pin of Row I/O Banks 1, 2, 5, and 6. Emulated RSDS transmitter is supported at the
output pin of all I/O Banks.
Cyclone IV GX devices—true RSDS transmitter is only supported at the output pin of Row I/O Banks 5 and 6. Emulated RSDS transmitter is supported at the output
pin of I/O Banks 3, 4, 5, 6, 7, 8, and 9.
(3) t is the time required for the PLL to lock from the end-of-device configuration.

(4) 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.
