digital-to-analog converter, including digital interpo-
lation 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 I
2
S data format.
The digital filter performs an 8X interpolation func-
tion, as well as special functions such as soft mute,
digital attenuation, and digital de-emphasis. The digi-
tal 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 re-
quired. Its low cost, small size, and single +5V power
supply make it ideal for automotive CD players, book-
shelf CD players, BS tuners, keyboards, MPEG audio,
MIDI applications, set-top boxes, CD-ROM drives,
CD-Interactive, and CD-Karaoke systems.

ZERO
Operational Controls and Flags
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.
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.
