Table 6-27: HSTL Class I (1.2V) DC Voltage Specifications
The Stub-Series Terminated Logic (SSTL) for 2.5V (SSTL2) and 1.8V (SSTL18) standards are
for general purpose memory buses. SSTL2 is defined by the JEDEC standard JESD8-9B and
SSTL18 is defined by the JEDEC standard JESD8-15. The SSTL2 standard has two classes;
Class I is for unidirectional and class II is for bidirectional signaling. Virtex-5 FPGA I/O
supports both standards for single-ended signaling and differential signaling. This
standard requires a differential amplifier input buffer and a push-pull output buffer.
