Figure 4. On-Board LAN Block Diagram
On the development board, the LAN connector supported is a stacked RJ45 with dual
USB connector (J4A1). The top port is RJ45 and middle and bottom ports are USB2.0
There is also an option to support PHY on dock. If this is desired, users must plug a
card with a PHY into the PCIe slot 2 (J2D1) on the Saddle String 3 add-in card.

Soft Audio and Modem
Intel High Definition Audio functionality is enabled through the Mott Canyon 4
daughter card. The PCH supports four Intel HD audio codecs. All four are routed to
Mobile Daughter Card (MDC) header through resistor stuffing options. By default,
codec 0 and 1 are connected to the card. An on-board header is provided at J9E6 and
J9E8 for this purpose. No direct connection is provided for the Intel HD Audio Card on
the development board; the Mott Canyon 4 card is required to enable the Intel HD
Audio functionality.
The development board supports low-voltage (LV), high-definition codecs I/O. R8E1,
R8R11, and R8R12, R8R10 resistors are used to select between 3.3 V I/O and 1.5 V
I/O.

Realtek* Audio Card Support
For users who want to use the Realtek* audio card, the PCIe-268Q* is an audio card
with PCIe full-size form factor. Through HDA connector and an extra ATX P4 power
connector, PCIe-268Q can support external speakers (up to 2.3W/ch), microphone-in,
line-in, headphone-out, and SPDIFout ports (in current operating systems, all ports
working at the same time is not supported). The PCIe-268Q also supports to connect
two sets of digital microphone modules. With customized driver, multiple streaming
can be supported for recording and playback by individual ADC and DAC. On-board,
power measuring resistors are reserved for easy probing to measure the power
consumption when different use-case scenarios.
