    PCM1802EVM and PCM1803AEVM Evaluation Module ABSTRACT This user's guide describes the function and use of the PCM1802EVM and PCM1803AEVM. This document includes the hardware configuration instructions, a quick-start guide, jumper and connector descriptions, schematics, and printed-circuit board (PCB) layout that demonstrate TI's recommended practices for these devices.

  • Page 2: Introduction

    S, right-justified (RJ), and left-justified (LJ) formats. 3 Power Supply The PCM1802EVM and PCM1803AEVM are powered with a single 5-V power supply connected to J17. An onboard low-dropout regulator converts the 5-V supply to the 3.3-V rail used by the ADC. The analog supply, VCC, is fixed at 5 V and the digital supply, VDD, is fixed at 3.3 V.

    32-BCK per frame format. Although BCK and LRCK are no longer derived from SCKI in peripheral mode, a valid SCKI is still required for operation. Table 4-1. PCM1802EVM and PCM1803AEVM Headers and Jumpers Designator Function...
  • Page 4 In addition, the SCKI signal can be sourced from an onboard oscillator or provided externally at J9. J4 selects the SCKI clock source (SCK_OSC) or externally from J9 (SCK_IN) by changing the position of J4 as shown in Table 4-7. Table 4-7.
