DESCRIPTION
The PCM1710 is a complete stereo audio digital-to-
analog converter, including digital interpolation filter,
delta-sigma DAC, and analog voltage output. PCM1710
can accept either 16-bit normal or 20-Bit normal input
data (MSB first, right justified), or 16-bit IIS data
(32-bits per word, continuous clock).
The digital filter performs an 8X interpolation func-
tion, as well as special functions such as soft mute,
digital attenuation, de-emphasis and double-speed
dubbing. Performance of the digital feature is excel-
lent, featuring –62dB stop band attenuation and
±0.008dB ripple in the pass band.
PCM1710 is suitable for a wide variety of 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.
