In the following table are signals associated with the HyperTransport links. In the signal names:
In the table columns:

Pin Name. Description
L[1,0]_CADIN_[H,L][15:0]. HyperTransport™ links 1 and 0 receive
command-address-data bus.
L[1,0]_CADOUT_[H,L][15:0]. HyperTransport™ links 1 and 0 transmit
command-address-data bus.
L[1,0]_CLKIN_[H,L][1:0]. HyperTransport™ links 1 and 0 receive link
clocks.
L[1,0]_CLKOUT_[H,L][1:0]. HyperTransport™ links 1 and 0 transmit link
clocks. Bit 1 corresponds to CADOUT[15:8].
L[1,0]_COMP_[PU,PD]. HyperTransport™ impedance compensation pins
for both sides of the tunnel. These are designed to be connected through
resistors as follows:
L[1,0]_COMP_PU = pullup to VDD
L[1,0]_COMP_PD = pulldown to VSS
L[1,0]_CTLIN_[H,L]0. HyperTransport™ links 1 and 0 receive control
signal.
L[1,0]_CTLOUT_[H,L]0. HyperTransport™ links 1 and 0 transmit control
signal.
LDTREQ_L. HyperTransport™ wake up.
LDTRESET_L. Reset input. See section 4.2.1 for details. LDTRESET_L is
also used as the hot-plug [B,A]_HPSOR_L reset. When LDTRESET_L is
asserted, the hot-plug shift register and control latches are reset.
LDTSTOP_L. Link disconnect control signal.
PWROK. Power OK. 1 = All power planes and REFCLK are valid. The
rising edge of this signal is deglitched; it is not observed internally until it is
high for more than six consecutive REFCLK cycles. Behavior follows the
requirements in HyperTransport™I/O Link Specification, Rev 2.0. For more
details about this signal, see section 4.2.1.
Notes:
** Diff High and Diff Low for these link pins specify differential high and low; e.g: Diff High specifies that the _H signal is
• [1,0] refers to the two sides of the tunnel.
• [H,L] refers to the positive and negative sides of differential pairs.
• _L in single-ended signals indicates the signal is active low.
