DESCRIPTION
The PCM1723 is a complete low cost stereo audio
digital-to-analog converter (DAC) with a phase-locked
loop (PLL) circuit included. The PLL derives either
256f
S
or 384f
S
system clock from an external 27MHz
reference frequency. The DAC contains a 3rd-order
Σ
modulator, a digital interpolation filter, and an analog
output amplifier. The PCM1723 can accept 16-, 20-, or
24-bit input data in either normal or I
2
S formats.
The digital filter performs an 8X interpolation func-
tion and includes selectable features such as soft mute,
digital attenuation and digital de-emphasis. The PLL
can be programmed for sampling at standard digital
audio frequencies as well as one-half and double
sampling frequencies.
The PCM1723 is ideal for applications which combine
compressed audio and video data such as DVD, DVD-
ROM, set-top boxes and MPEG sound cards.
