Notes to Table 8–1:
(1) The HardCopy IV E device family does not offer a 1760-pin package.
(2) The Stratix IV device EP4SE230F780 offers 56Rx + 56Tx or 112eTx channels and therefore has more transceiver
channels than a HardCopy IV E device with the wire-bond package.
(3) Stratix IV devices EP4SE530F1517 and EP4SE820H1517 offer 112Rx + 112Tx or 224eTx channels and therefore
have more transceiver channels than HardCopy IV E devices.
Table 8–2 shows the LVDS channels supported in HardCopy IV E device top and
bottom (column) I/O banks.

Notes to Table 8–2:
(1) LVDS input buffers at top and bottom I/O banks are true LVDS input buffers. All user I/Os, including I/Os with true
LVDS input buffers, can be configured as emulated LVDS output buffers.
(2) Rx = true LVDS input buffers with OCT RD, Tx = true LVDS output buffers, and eTx = emulated LVDS output buffers
(either LVDS_E_1R or LVDS_E_3R).
(3) Stratix IV device EP4SE230F780 offers 64 Rx + 64 eTx or 128 eTx channels and therefore has more transceiver
channels than a HardCopy IV E device with the wire-bond package.
Table 8–3 shows the LVDS channels supported in HardCopy IV GX device row I/O
banks.
