HyperTransport Protocol (HT)
Reduced Swing Differential Signaling (RSDS)
BLVDS (Bus LVDS)
The HyperTransport™ protocol (HT) also known as Lightning Data Transport (LDT), is a
low-voltage standard for high-speed interfaces. Its differential signaling based interface is
very similar to LVDS. Virtex-5 FPGA IOBs are equipped with HT buffers.
summarizes all the possible HT I/O standards and attributes supported.
Table 6-37: Allowed Attributes of the HT I/O Standard
Reduced Swing Differential Signaling (RSDS) is similar to an LVDS high-speed interface
using differential signaling. RSDS has a similar implementation to LVDS in Virtex-5
devices and is only intended for point-to-point applications.
Table 6-38: Allowed Attributes of the RSDS I/O Standard
Since LVDS is intended for point-to-point applications, BLVDS is not an EIA/TIA standard
implementation and requires careful adaptation of I/O and PCB layout design rules. The
primitive supplied in the software library for bidirectional LVDS does not use the Virtex-5
FPGA LVDS current-mode driver, instead, it uses complementary single-ended differential
drivers. Therefore, source termination is required.
