If the phase difference between left-right and system clocks is greater than 6-bit clocks (BCKIN), the synchronization is performed internally. While the synchro- nization is process

34、ing, the analog output is forced to a DC level at bipolar zero.

Figure 4 shows required timing specification for digital audio data.ResetPCM1716 has both internal power-on reset circuit and the RST pin (pin 22) which accepts an external forced reset by RST = LOW. For internal power on reset, initialize (reset) is done auto

37、matically at power on VDD 2.2V (typ). During internal reset = LOW, the output of the DAC is invalid and the analog outputs are forced to VCC /2. Figure 5 illustrates the timing of the internal power on reset.PCM1716 accepts an external forced reset when RST = L. When RST = L, the output of the DAC i

Figure 6 illustrates the timing of the RST pin.Zero Out (pin 21)If the input data is continuously zero for 65536 cycles of BCK, an internal FET is switched to “ON”. The drain

39、of the internal FET is the zero-pin, it will enable “wired-or” with external circuit. This zero detect function is available in both software mode and hardware mode.SAMPLING RATE FREQUENCY (fS) - LRC384fS512fS768fS32kHz8.192012.288016.384024.576044.1kHz11.289616.934022.579233.8688(1)48kHz12.288018.4

Software mode is a three-wire interface using pin 28 (ML), 27 (MC), and 26 (MD).PCM1716 can also be operated in hardware mode, where static control signals are used on pin 28 (115, pin 27 (DM1), pin 26 (DM0) and pin 23 (IWO).This basic operation mode as software or hardware can be selected by pin 24 (MODE) as shown in Table II.MODE (pin 24) = HSoftware ModeMODE (pin 24) = LHardware ModeTABLE II.
