(SLEU094) Input-USB Board 2 User's Guide (2.00)
1 Overview
The board has 8 channels analog to digital converter, SPDIF receiver (coax and optical) and a USB connection for PC to I2C control.
This board, together with a PurePath amplifier EVM, can be a complete 8 channel digital audio amplifier system which includes digital input (S/PDIF), analog inputs, interface to
PC. There are reporting of shutdowns and over temperature warning from the EVM.
The board can also be connected to PurePath digital audio processor EVM.

2 Quick Setup Guide
The chapter provides information regarding handling and unpacking, absolute operating conditions, and a description of the factory default switch and jumper configuration.
2.1 Electrostatic Discharge Warning
Many of the components on the Input-USB Board 2 are susceptible to damage by electrostatic discharge (ESD). Customers are advised to observe proper ESD handling precautions when unpacking and handling the EVM, including the use of a grounded wrist strap at an approved
ESD workstation.
Caution: Failure to observe ESD handling procedures may result in damage to EVM components.
CAUTION
2.2 Unpacking the board
This Board will always be shipped as part of PurePath Evaluation Kit.

(SLEU094) Input-USB Board 2 User's Guide (2.00)
2.3 Power Supply Setup
The Input-USB Board 2 is intended to be powered from the enclosed +15 VDC Power Supply via
J600. The Input-USB Board 2 is delivering +5 VDC and +12 VDC to the connected TI EVM.

Caution: Applying voltages above the limitations given in table
CAUTION
2.4 Audio Source Connection and Default start up
After each reset, either auto-generated during power up sequence or manual pressing RESET button, the Input-USB board will always in following configuration:
• Analog input set to 48kHz sample rate
To start up a PurePath EVM use following procedure:
1) Turn on all power supplies before connecting USB interface
2) Connect USB interface and press RESET button
3) Start GUI software and press RESET in GUI window. Make sure that “USB attached” LED is on and status indicator changes to “ok”
4) Load EVM configuration file. Make sure to select the correct file according to the EVM in use.
5) Press MUTE to unmute EVM
6) EVM is ready to use

2.5 GUI Software Interface
The Input-USB board supports the following GUI’s
• TAS5508 GUI 4.0 or later
• TAS5518 GUI 4.0 or later
• TAS5504 GUI 4.0 or later
• TAS5086 GUI 4.0 or later
• Command Tool 6.01 or later
• Other GUI’s programmed for TUSB3210
Input-USB Board 2 7
(SLEU094) Input-USB Board 2 User's Guide (2.00)
This chapter describes more advanced used of the Input-USB board.
3.1 Analog Sample Rate
The Input-USB board has 8 analog inputs. Default these inputs are converted to digital at a sample rate of 48kHz. By pressing SW604 “Analog Sample Rate” this can be changed to 96kHz.
LED’s will show which sample rate is selected.
Note that after each power up and reset sample rate will always return to default 48kHz.
Connector J301 has pin outs for I2C. This connector is intended for external I2C monitoring.
By removing R469 and R474 this connector can also be used for control of I2C. Removing the resistors will disconnect USB device from I2C bus.
Caution: I2C bus will always be pulled up to onboard 3.3V rail via
CAUTION
3.3 AP PSIA Interface
The Input-USB board provides the possibility to use I2S directly into the PurePath EVM. I2S source could e.g. be an Audio Precision with a Programmable Serial Interface Adaptor, PSIA.
Default jumper setting is shown in Figure 4. In this setting data out will be: Analog 1+2 routed to
Data1, Analog 3+4 to Data2 etc. when analog inputs are selected. When digital input is selected either Coax or Toslink channel A+B is copied into all data outputs.
