Electrostatic Discharge Warning
Many of the components on the TAS3308EVM 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.
Upon opening the TAS3308EVM package, please check to make sure that the following items are
included:
•
TAS3308EVM board using one TAS3308DCP (1 pc.)
•
PurePath CD-ROM containing data sheets, application reports, user guides, Gerber files, and PC
software tools (1 pc.)
If any of these items are missing, please contact the Texas Instruments Product Information Center
nearest you to inquire about a replacement.
The TAS3308EVM is powered via the
±
9 V terminals or the 9 V (center hot) power connectors, PJ1 and
PJ2. The TAS3308 EVM generates a 5-V, –5-V, and 3.3-V internal supplies that are fed to the
TAS3308EVM components.
Set the power supplies to
±
9 V. Then turn off the supplies and them to the EVM.
Once the cables are connected, switch on the power supply. Current consumption should be less than
shown in
Table 2-1 , if higher switch off and double check the cabling.
Table 2-1. Recommended Supply Voltages for EVM Board
Description Voltage Limitations Current Requirement
9 V 8.5 V – 9.5 V 0.3 A
–9 V –8.5 V – 9.4 V 0.1 A
CAUTION
Applying voltages above the limitations given in Table 2-1 may cause
permanent damage to your hardware.
The digital audio inputs can be connected to the board in two ways, either in the SPDIF format optical
TOSLINK input, OPTO1, or in I
2
S format on connector J1. The pin out this and the other connectors is
shown in Chapter 3.
The SPDIF I
2
S IN input supplies signal to the TAS3308 SDIN1. When a valid lock is detected by the
DIR9001 SPDIF receiver a blue SPDIF lock LED is lit.
