  • Page 7: Functional Description

    Philips Semiconductors Low power audio DAC FUNCTIONAL DESCRIPTION System clock The UDA1334BT operates in slave mode only; this means that in all applications the system must provide the system clock and the digital audio interface signals (BCK and WS). The system clock must be locked in frequency to the digital interface signals.

  • Page 19 1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note ” (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect).
