19、(16 to 50 kHz sample rates) Common Clock Frequencies Serial Clock - SCLK Pin 11, Input Function: Clocks individual bits of serial data into the SDATA pin. The required relationship between the Left/Right clock, serial clock and serial data is defi ned by either the Mode Control Byte in Control Port

20、Mode or the M0 - M4 pins in Hardware Mode. The options are detailed in Figures 29-33 Left/Right Clock - LRCK Pin 12, Input Function: The Left/Right clock determines which channel is currently being input on the serial audio data input, SDATA. The frequency of the Left/Right clock must be at the inpu

21、t sample rate. Audio samples in Left/Right sample pairs will be simultaneously output from the digital-to-analog converter whereas Right/Left pairs will exhibit a one sample period difference. The required relationship between the Left/Right clock, serial clock and serial data is defi ned by the Mod

22、e Control Byte and the options are de- tailed in Figures 29-33 Serial Audio Data - SDATA Pin 13, Input Function: Serial audio data is input on this pin. The selection of the Digital Interface Format is determined by set- tings of the Mode select as detailed in Figures 29-33. The data is clocked into

23、 SDATA via the serial clock and the channel is determined by the Left/Right clock. The required relationship between the Left/Right clock, serial clock and serial data is defi ned by the Mode Control Byte and the options are detailed inin Figures 29-33 Soft Mute - MUTE Pin 15, Input Function: The an

24、alog outputs will ramp to a muted state when enabled. The ramp requires 1152 left/right clock cy- cles in Single Speed, 2304 cycles in Double Speed and 4608 cycles in Quad Speed mode. The bias volt- age on the outputs will be retained and MUTEC will go active at the completion of the ramp period. Th

25、e analog outputs will ramp to a normal state when this function transitions from the enabled to disabled state. The ramp requires 1152 left/right clock cycles in Single Speed, 2304 cycles in Double Speed and 4608 cycles in Quad Speed mode. The MUTEC will release immediately on setting MUTE = 1. The

26、converter analog outputs will mute when enabled. The bias voltage on the outputs will be retained and MUTEC will go active during the mute period.

30、wer - VA Pin 22, Input Function: Power for the analog and reference circuits. Typically 5VDC. QD61 : CS4397 1920 Common Mode Voltage - CMOUT Pin 25, Output Function: Filter connection for internal bias voltage, typically 50% of VREF. Capacitors must be connected from CMOUT to analog ground, as shown

31、 in Figure 6. CMOUT has a typical source impedence of 25 k and any current drawn from this pin will alter device performance Reference Ground - FILT- Pin 26, Input Function: Ground reference for the internal sampling circuits. Must be connected to analog ground. Reference Filter - FILT+ Pin 27, Outp

32、ut Function: Positive reference for internal sampling circuits. External capacitors are required from FILT+ to analog ground, as shown in Figure 6. FILT+ is not intended to supply external current. Voltage Reference Input- VREF Pin 28, Input Function: Analog voltage reference. Typically 5VDC. HARDWA

33、RE MODE Mode Select - M0, M1, M2, M3, M4 Pins 2, 3, 4, 5 and 14, Inputs Function: The Mode Select pins determine the operational mode of the device as detailed in Tables 9-14. The op-tions include; Selection of the Digital Interface Format which determines the required relationship between the Left/

34、Right clock, serial clock and serial data as detailed in Figures 29-33 Selection of the standard 15 s/50 s digital de-emphasis fi lter response, Figure 28, which requires re-confi guration of the digital fi lter to maintain the proper fi lter response for 32, 44.1 or 48 kHz sample rates. Selection o

Access to the Direct Stream Digital Mode Access to the 8x Interpolation Input Mode CONTROL PORT MODE Address Bit 0 / Chip Select - AD0 / CS Pin 2, Input Function: In I2C mode, AD0 is a chip address bit. CS is used to enable the control

36、 port interface in SPI mode. The device will enter the SPI mode at anytime a high to low transition is detected on this pin. Once the device has entered the SPI mode, it will remain until either the part is reset or undergoes a power-down cycle. Address Bit 1 / Control Data Input - AD1/CDIN Pin 3, I

37、nput Function: In I2C mode, AD1 is a chip address bit. CDIN is the control data input line for the control port interface in SPI mode. Serial Control Interface Clock - SCL/CCLK Pin 4, Input Function: In I2C mode, SCL clocks the serial control data into or from SDA/CDOUT. In SPI mode, CCLK clocks the

38、 serial data into AD1/CDIN and out of SDA/CDOUT. Serial Control Data I/O - SDA/CDOUT Pin 5, Input/Output Function: In I2C mode, SDA is a data input/output. CDOUT is the control data output for the control port interface in SPI mode. M1 - Mode Select Pin 14, Input Function: This pin is not used in Co
