LAN Connector
The KTT30 uses an Intel
®
82574 Gigabit PCI Express
®
LAN controller which supports 10/100/1000 Base-T
interfaces. The controller auto-negotiates the management of a 10, 100 or 1000 Mbps connection. Addi-
tionally you can boot up the board via a network connection from a PXE server.
The LAN interface is available through the standard RJ45 connector J8 (8 pins).

Audio Interface
The SoC supports an Inter-IC Sound (I
2
S) codec with 24 bit resolution and 96 kHz sample rate (the
maximum rate of 96 kHz only unidirectional). The analogue-to-digital part of the codec uses 24 bit, 128x
oversampled sigma-delta ADCs. The digital-to-analogue part contains two 24 bit sigma-delta DACs. The
interface includes LINE OUT, LINE IN, MICROPHONE IN and a digital S/PDIF output.

Analog Connectors
The analog audio interface uses three TRS (Tip, Ring, Sleeve) connectors J9 to J11 (3 pins).
