PCM1721 - DIGITAL-TO-ANALOG CONVERTER
The PCM1721 is a complete low cost stereo audio digital-to-analog converter (DAC) with a phase-locked loop (PLL) circuit included.
The PLL derives either 256fS or 384fS system clock from an external 27MHz reference frequency.
The DAC contains a 3rd-order ∆Σ modulator, a digital interpolation filter,
