LVDS Channels
Table 8–1 and Table 8–2 list the maximum number of row and column LVDS I/Os
supported in Stratix IV E devices. You can design the LVDS I/Os as true LVDS buffers
or emulated LVDS buffers, as long as the combination of the two do not exceed the
maximum count.
For example, there are a total of 112 LVDS pairs on row I/Os in the 780-pin EP4SE230
device (refer to Table 8–1). You can design up to a maximum of 56 true LVDS input
buffers and 56 true LVDS output buffers, or up to a maximum of 112 emulated LVDS
output buffers. For the 780-pin EP4SE230 device (refer to Table 8–2), there are a total
of 128 LVDS pairs on column I/Os. You can design up to a maximum of 64 true LVDS
input buffers and 64 emulated LVDS output buffers, or up to a maximum of 128
emulated LVDS output buffers.

Notes to Table 8–1:
(1) Receiver (Rx) = true LVDS input buffers with OCT RD, Transmitter (Tx) = true LVDS output buffers, eTx = emulated LVDS output buffers (either
LVDS_E_1R or LVDS_E_3R).
(2) The LVDS Rx and Tx channels are equally divided between the left and right sides of the device.
(3) The LVDS channel count does not include dedicated clock input pins.
(4) EP4SE360 devices are offered in the H780 package instead of the F780 package.
(5) EP4SE530 devices are offered in the H1152 package instead of the F1152 package.
(6) EP4SE530 devices are offered in the H1517 package instead of the F1517 package.
