Philips Semiconductors Product specification Low power audio DAC 8 UDA1334BT Table 2 FUNCTIONAL DESCRIPTION 8.1 System clock Example using a 12.228 MHz system clock CLOCK MODE SAMPLING FREQUENCY 128fs 96 kHz 192fs 64 kHz(1) 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.
Philips Semiconductors Product specification Low power audio DAC 8.4 UDA1334BT Filter stream DAC 8.5 The FSDAC is a semi-digital reconstruction filter that converts the 1-bit data stream of the noise shaper to an analog output voltage. The filter coefficients are implemented as current sources and are summed at virtual ground of the output operational amplifier. In this way very high signal-to-noise performance and low clock jitter sensitivity is achieved.
Philips Semiconductors Product specification Low power audio DAC 8.6 UDA1334BT 8.6.4 Feature settings The features of the UDA1334BT can be set by control pins SFOR1, SFOR0, MUTE, DEEM and PCS. 8.6.1 Pin PCS is a 3-level pin and is used to set the mode of the UDA1334BT. The definition is given in Table 7. DIGITAL INTERFACE FORMAT SELECT Table 7 The digital audio interface formats (see Fig.5) can be selected via the pins SFOR1 and SFOR0 as shown in Table 4.
