Digital-to-analog Converter With Programmable Pll Corporation

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 Modulator a digital interpolation Filter and an Analog output Amplifier The PCM1721 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 PLL CAN be programmed for sampling at standard digital Audio frequencies as well as one-half and double sampling frequencies. The PCM1721 is ideal for applications which combine compressed Audio and Video data such as DVD, DVD- ROM, set-top boxes and MPEG sound cards. By Texas Instruments
