PCM1690 www.ti.com.............................................................................................................................................. SBAS448A – OCTOBER 2008 – REVISED JANUARY 2009 PRODUCT OVERVIEW The PCM1690 is a high-performance, multi-channel DAC targeted for consumer audio applications such as Blu-ray DVD players and HD DVD players, as well as home multi-channel audio applications (such as home theaters and A/V receivers). The PCM1690 consists of an eight-channel DAC.
PAGE 14
PCM1690 SBAS448A – OCTOBER 2008 – REVISED JANUARY 2009.............................................................................................................................................. www.ti.com SYSTEM CLOCK INPUT The PCM1690 requires an external system clock input applied at the SCKI input for DAC operation. The system clock operates at an integer multiple of the sampling frequency, or fS.
PAGE 15
PCM1690 www.ti.com.............................................................................................................................................. SBAS448A – OCTOBER 2008 – REVISED JANUARY 2009 SAMPLING MODE The PCM1690 supports three sampling modes (single rate, dual rate, and quad rate) in DAC operation. In single rate mode, the DAC operates at an oversampling frequency of x128 (except when SCKI = 128 fS and 192 fS). This mode is supported for sampling frequencies less than 50 kHz.
PAGE 16
PCM1690 SBAS448A – OCTOBER 2008 – REVISED JANUARY 2009.............................................................................................................................................. www.ti.com RESET OPERATION The PCM1690 has both an internal power-on reset circuit and an external reset circuit. The sequences for both reset circuits are illustrated in Figure 20 and Figure 21. Figure 20 describes the timing at the internal power-on reset.

PCM1690 www.ti.com.............................................................................................................................................. SBAS448A – OCTOBER 2008 – REVISED JANUARY 2009 AUDIO SERIAL PORT OPERATION The PCM1690 audio serial port consists of six signals: BCK, LRCK, DIN1, DIN2, DIN3, and DIN4. BCK is a bit clock input. LRCK is a left/right word clock input or frame synchronization clock input. DIN1/2/3/4 are the audio data inputs for VOUT1–8.

PCM1690 www.ti.com.............................................................................................................................................. SBAS448A – OCTOBER 2008 – REVISED JANUARY 2009 SYNCHRONIZATION WITH THE DIGITAL AUDIO SYSTEM The PCM1690 operates under the system clock (SCKI) and the audio sampling rate (LRCK). Therefore, SCKI and LRCK must have a specific relationship.
PAGE 22
PCM1690 SBAS448A – OCTOBER 2008 – REVISED JANUARY 2009.............................................................................................................................................. www.ti.com AMUTE CONTROL The PCM1690 has an AMUTE control input, status output pins, and functionality. AMUTEI is the input control pin of the internal analog mute circuit. An AMUTEI low input causes the DAC output to cut-off from the digital input and forces it to the center level (0.5 VCC1).
