HSTL

LVDS보다 전압이 더 낮은 기분인데...?

The nominal signaling range is 0 V to 1.5 V, though variations are allowed, and signals may be single-ended or differential. It is designed for operation beyond 180 MHz.

The following classes are defined by standard EIA/JESD8-6 from EIA/JEDEC:

Class I (unterminated, or symmetrically parallel terminated)

Class II (series terminated)

Class III (asymmetrically parallel terminated)

Class IV (asymmetrically double parallel terminated)
