USB Interfaces

The ReadyBoard 910 offers state-of-the-art USB 3.0 support through the PCH using PCIe x1 Port 1 and a

USB 3.0 xHCI host controller module. Features of the USB 3.0 interface include up to two downstream
ports (each independently enabled or disabled), SuperSpeed, High-Speed, and Full-Speed signals, and

support for input frequencies between 20MHz and 50MHz. An 18-pin, standard dual-port connector (CN15)

delivers the signals for two USB 3.0 ports, ideal for HDTV, set-top box, and gaming console applications.

The PCH (BD82HM65) provides a USB solution for legacy UHCI controller and EHCI controller (USB

2.0) support. The PCH contains port-routing logic that determines which controller (UHCI or EHCI) handles

the USB data signals. A 10-pin header (CN14) delivers the signals for two USB 2.0 ports.

Table 3-5

describes the pin signals for the USB 2.0 interface, which provides a 10-pin, 2-row, header with

odd/even (1, 2) pin sequence and 0.100" (2.54mm) pitch. The USB 3.0 interface provides a standard
interface and those signals are not provided in this manual. See

Chapter 1

for a hyperlink to the USB 3.0

specification and the USB 3.0 pin signals.

Note: The shaded table cells denote power or ground.

Audio Interface

The audio solution on the ReadyBoard 910 is provided by the PCH (BD82HM65) and the on-board Audio

CODEC (ALC262). These two chips use the Intel HDA Link protocol to communicate between the two,
complying with the Intel HDA Specification 1.0a. The audio interface uses the 10-pin audio header (CN10),

and the audio signals are defined in

Table 3-6

. The ReadyBoard 910 also features an S/PDIF Digital Audio

interface, and those signals are defined in

Table 3-7

.

Audio CODEC (ALC262) features:

Comply with HDA Specification 1.0a

Provide high-performance DACs with 100dB SNR

Provide ADCs with 90dB SNR (A-weighting)

Support 44.1/48/96/192kHz sample rate on all DACs

Support 44.1/48/96/kHz sample rate on all ADCs

Support 44.1/48/96/192kHz sample rate on 16/20/24-bit S/PDIF interface

Support multiple channels of microphone input
