DX-V88W
IC17 VHiPCM1717E-1: DA Converter (PCM1717E)
Pin Terminal NameFunction
No.
1XT1Oscillator Input (External Clock Input). For an internal clock, tie XTI to one side of the crystal oscillator. For an
external clock, tie XTI to the output of the chosen external clock.
2DGNDDigital Ground.
3VDDDigital Power Supply (+5V).
4LRCINSample Rate Clock Input. Controls the update (fs).
5DINSerial Data Input. MSB first, right justified (Sony format) or I2S (Philips). Contains a frame of 16-or 18-bit data,
6BCKINBit Clock Input. Clocks in the data present on DIN input.
7*ZEROInfinite Zero Detection Flag, open drain output. When the zero detection feature is muting the output, ZERO is
"LOW". When non-zero input data is present, ZERO is in a high impedance state. When the input data is
continuously zero for 65.536 BCKIN cycles, zero will be low.
8D/C_RRight Channel Output Amplifier Common. Bypass to ground with 10 mF capacitor.
9VOUT RRight Channel Analog Output. V OUT max = 0.62 x Vcc.
10AGNDAnalog Ground.
11VccAnalog Power Supply (+3V).
12VOUT LLeft Channel Analog Output. V OUT max = 0.62 x Vcc.
13D/C_LLeft Channel Output Amplifier Common. Bypass to ground with 10 mF capacitor.
14MODEOperation Mode Select. For Software Mode, tie Mode "HIGH". For Hardware Mode, tie Mode "LOW".
15RSTBResets DAC operation with an active "LOW" pulse.
16MD/DM0Mode Control for Data Input or De-emphasis. When "HIGH" MD is selected, and a "LOW" selects DM0.
17MC/DM1Mode Control for BCKIN or De-emphasis. When "HIGH", MC is selected, and a "LOW" selects DM1.
18ML/MUTEMode Control for Strobe Clock or Mute. When "HIGH", ML is selected, and a "LOW" selects mute.
19CLKOBuffered Output of Oscillator. Equivalent to XTI.
20XTOOscillator Output. When using the internal clock, tie to the opposite side (from pin 1) of the crystal oscillator.
When using an external clock, leave XTO open.
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
