TLV320AIC13 TLV320AIC14 TLV320AIC15 This guide refers to the TLV320AIC12 only, since the remaining device feature sets are subsets of the TLV320AIC12. Any important differences are noted. Figure 1−1. EVM The EVM is split into two complementary halves as shown in Figure 1−1. -
Page 11: Digital Interface
Chapter 2 Digital Interface The digital signals required to operate this codec originate from the 40-pin connector—J1. There are two methods to drive the digital interface: Create a custom interface between the codec EVM and the host system. Alternatively, if a TI DSK (DSP starter kit) is the host system, a develop- ment platform is available from TI. -
Page 12: Codec-To-Platform
Codec-to-Platform 2.1 Codec-to-Platform The TLV320AIC12, 13, 14, and 15 mate with the development platform via a 40-pin Samtec connector. The mating connector (Samtec part number, TSM-120-01-T-DV-P) is used on the development platform to provide the electrical connections necessary. Consult Samtec at www.samtec.com... -

Page 14: Jumper Options
Jumper Options 2.3 Jumper Options There are various jumpers on the board that can be configured in various ways, depending upon the user’s requirements. Their functions are briefly presented in Table 2−2: Table 2−2. Jumper Options Jumper Function Selects whether U2 is either a master or a slave codec Used along with W2 for correct polarity for FSD Manages FSD from the master. -

Page 16: Slave/Slave Cascade
System Level Considerations 2.3.4 Slave/Slave Cascade This configuration applies to additional EVMs that may be installed for additional channels. It does not apply to EVM1. Both U1 and U2 are slave codecs to the master codec, which resides on EVM1. Follow the jumper settings detailed in Table 2−6. -
