The PCM514x uses the latest generation of TI’s advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. Members of the PCM514x family integrate a fully programmable mini DSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators, and other differentiating features to their products. The PCM514x provides 2.1-VRMS ground centered outputs, allowing designers to eliminate DC-blocking capacitors on the output, as well as external muting circuits traditionally associated with single-supply line drivers. The integrated line driver surpasses all other chargepump-based line drivers by supporting loads down to 1 kΩ, allowing the PCM514x to drive up to 10 products in parallel, such as LCD TV, DVDR, and AV receivers. The integrated PLL on the device removes the requirement for a system clock (monly known as master clock),...
