DESCRIPTION
The PCM1727 is a complete low cost stereo audio
digital-to-analog converter (DAC) with a dual phase-
locked loop (PLL) circuit included. PLL-1 derives a
fixed 33.8688MHz (768fS, fS = 44.1kHz) system
clock (SCKO-1), and PLL-2 derives both the 384fS (fS
= 44.1k/48k/96kHz) system clock (SCKO-2), and the
768fS (fS = 44.1k/48kHz)/384fS (fS = 96kHz) system
clock (SCKO-3) from an external 27MHz reference
frequency. The DAC contains a 3rd-order ∆Σ modula-
tor, a digital interpolation filter, and an analog output
amplifier. The PCM1727 can accept 16-, 20-, or 24-bit
input data in either normal or I2S 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 PCM1727 is ideal for applications which combine
compressed audio and video data such as DVD, DVD
Audio with CD-DA compatibility, karaoke DSP.

NOTES: (1) Sysclk transient is the maximum frequency lock time when the PLL frequency is changed. (2) Dynamic performance specs are tested with 20kHz low
pass filter and THD+N specs are tested with 30kHz LPF, 400Hz HPF, Average-Mode. (3) SNR is tested at Infinite Zero Detection off. (4) PLL evaluations tested
with 1ns maximum jitter on the 27MHz input clock.
