HSLVDCI (High-Speed Low Voltage Digitally Controlled Impedance)
The HSLVDCI standard is intended for bidirectional use. The driver is identical to LVDCI,
while the input is identical to HSTL and SSTL. By using a V
HSLVDCI allows greater input sensitivity at the receiver than when using a single-ended
LVCMOS-type receiver.
Sample circuits illustrating both unidirectional and bidirectional termination techniques
for an HSLVDCI controlled impedance driver are shown in
The DCI I/O standards supporting a controlled impedance driver with a V
input are: HSLVDCI_15, HSLVDCI_18, HSLVDCI_25, and HSLVDCI_33.
