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 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.

Codec-to-Platform 2.1 Codec-to-Platform The TLV320AIC12K, and 14K 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 1−800−SAMTEC−9 for more information. - Page 13 Codec-to-Platform Table 2−1.

Chapter 3 Analog Interface Table 3−1 indicates the applicable connectors for each codec in the family. In order to enable a wide range of sources and loads to be connected to the codecs, screw terminals have been used wherever possible. Table 3−1. - Page 18 Chapter 4 EVM Operation The EVM is shipped from the factory in master/slave cascade mode. To check if the EVM is working properly, simply install the EVM onto the development platform, and apply power to the DSK. The EVM should begin working immediately.
