Overview: ® 49% PCM1F7P27OE PCM1727 SBAS077 TM Stereo Audio DIGITAL-TO-ANALOG CONVERTER WITH PROGRAMMABLE DUAL.

General Description

The PCM1727 is a complete low cost stereo audio digital-to-analog converter (DAC) with a dual phaselocked 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 modulator, a digital interpolation filter, and an analog output amplifier.
