Description
CDMI_RCOMP[1:0]
I
Analog
CDMI_RCOMP: Connected to high-precision resistors on
the motherboard. Used for compensating cDMI pull-up/pull-
down impedances.
CDMI_TX[7:0]
O
CMOS
Data output: quad-pump (strobed) data bus from
Processor to PCH.
CDMI_TXCHAR#
O
CMOS
Data control character data control character output:
Quad-Pump (strobed) indication that CDMI_TX[7:0]
contains a control character instead of data.
CDMI_TXDPWR#
O
CMOS
Line wakeup for output: When asserted, the PCH will
power-up its receivers on CDMI_TX[7:0] and
CDMI_TXCHAR#, and CDMI_TXSTB[0].
CDMI_TXSTB_ODD#,
CDMI_TXSTB_EVEN#
O
CMOS
Data strobe output: Strobes for CDMI_TX[7:0] and
CDMI_TXCHAR#.
CDMI_RX[7:0]
I
CMOS
Data input: Quad-Pump (strobed) data bus from PCH to
Intel® Atom™ Processor Z670.
CDMI_RXCHAR#
I
CMOS
Data control character input: Quad-pump (strobed)
indication that CDMI_RX[7:0] contains a control character
instead of data.
CDMI_RXDPWR#
I
CMOS
Line wakeup for input: Power enable from PCH. Used to
enable Receivers on CDMI_RX[7:0], CDMI_RXCHAR#, and
CDMI_RXSTB_ODD#.
CDMI_RXSTB_ODD#,
CDMI_RXSTB_EVEN#
I
CMOS
Data strobe input: Strobes for CDMI_RX[7:0] and
CDMI_RXCHAR#.
CDMI_GVREF
I
Analog
Strobe Signals' Reference Voltage for DMI: Externally
set by means of a passive voltage divider. Voltage should be
1/2 VCCP when configured for CMOS.
CDMI_CVREF
I
Analog
Non-Strobe Signals' Reference Voltage for DMI:
Externally set by means of a passive voltage divider.
Voltage should be 1/2 VCCP when configured for CMOS.
