DESCRIPTION

The PCM1717 is a complete low cost stereo, audio
digital-to-analog converter, including digital interpo­lation filter, 3rd-order delta-sigma DAC, and analog
output amplifiers. PCM1717 is fabricated on a highly
advanced 0.6µ CMOS process. PCM1717 accepts
16- or 18-bit normal input data format, or 16- or
18-bit I2S data format.

The digital filter performs an 8X interpolation func­tion, as well as special functions such as soft mute,
digital attenuation, and digital de-emphasis. The digi­tal filter features –35dB stop band attenuation and
±0.17dB ripple in the pass band.

PCM1717 is suitable for a wide variety of cost-sensitive
consumer applications where good performance is re­quired. Its low cost, small size, and single +5V power
supply make it ideal for automotive CD players, book­shelf CD players, BS tuners, keyboards, MPEG audio,
MIDI applications, set-top boxes, CD-ROM drives,
CD-Interactive, and CD-Karaoke systems.

PIN CONFIGURATION

PIN NAME FUNCTION
Data Input Interface Pins

4 LRCIN Sample Rate Clock Input. Controls the update rate (fs).
5 DIN Serial Data Input. MSB first, right justified (Sony format)

or I

2

S (Philips). Contains a frame of 16- or 18-bit data.

6 BCKIN Bit Clock Input. Clocks in the data present on DIN input.

Mode Control and Clock Signals

1 XTI Oscillator 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.

14 MODE Operation Mode Select. For Software Mode, tie Mode

“HIGH”. For Hardware Mode, tie Mode “LOW”.

16 MD/DM0 Mode Control for Data Input or De-emphasis. When

“HIGH” MD is selected, and a “LOW” selects DM0.

17 MC/DM1 Mode Control for BCKIN or De-emphasis. When “HIGH”,

MC is selected, and a “LOW” selects DM1.

18 ML/MUTE Mode Control for Strobe Clock or Mute. When “HIGH”,

ML is selected, and a “LOW” selects mute.
19 CLKO Buffered Output of Oscillator. Equivalent to XTI.
20 XTO Oscillator 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.

Operational Controls and Flags

7 ZERO Infinite 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.
15 RSTB Resets DAC operation with an active “LOW” pulse.

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
