Lattice Semiconductor
Differential HSTL and SSTL
Differential HSTL and SSTL outputs are implemented as a pair of complementary single-ended outputs. All allow-
able single-ended output classes (class I and class II) are supported in this mode.
LVDS25E
The top and bottom side of LatticeXP devices support LVDS outputs via emulated complementary LVCMOS out-
puts in conjunction with a parallel resistor across the driver outputs. The scheme shown in Figure 3-1 is one possi-
ble solution for point-to-point signals.

Table 3-1. LVDS25E DC Conditions
BLVDS
The LatticeXP devices support BLVDS standard. This standard is emulated using complementary LVCMOS out-
puts in conjunction with a parallel external resistor across the driver outputs. BLVDS is intended for use when multi-
drop and bi-directional multi-point differential signaling is required. The scheme shown in Figure 3-2 is one possible
solution for bi-directional multi-point differential signals.
