PCI Express x16 4.8.2
The processor contains one PCI Express controller that supports one external
x16 PCI Express Graphics port. This port can also operate at Gen 2 speed,
5.0GT/s.

order.
4.9 High Definition Audio
The High Definition Audio (HDA) controller is integrated with PCH QM77. It
communicates with the external codec(s) over the Intel
®
High Definition Audio
serial link. The controller consists of a set of DMA engines that are used to
move samples of digitally encoded data between system memory and an
external codec(s). The PCH implements a single Serial Data Output signal
(HDA_SDOUT) that is connected to all external codecs. Three Serial Digital
Input signals (HDA_SDIN[0:02] provided by the PCH support up to three
codecs.
Signal I/O Description
AC/HDA_RST# O
Reset output to CODEC, active low
AC/HDA_SYNC O
Sample-synchronization signal to the CODEC(s)
AC/HDA_BITCLK I/O
Serial data clock generated by the external
CODEC(s)
AC/HDA_SDOUT O
Serial TDM data output to the CODEC
AC/HDA_SDIN[0:2] I/O
Serial TDM data input from up to 3 CODECs
4.10 Ethernet
The QM77 integrates a Gigabit Ethernet (GbE) controller. The controller with
Intel
®
82579LM LAN PHY provides 10/100/1000Mb/s interface. The Intel
®
82579 is connected to Port 7 of the PCIe x1 in the PCH. Gigabit transformer
has to be designed on the Carrier Board.
