3 Description
The PCM5242 is a monolithic CMOS integrated
circuit that includes a stereo digital-to-analog converter and additional support circuitry in a small
QFN package. The PCM5242 uses the latest
generation of TI’s advanced segment-DAC
architecture to achieve excellent dynamic performance and improved tolerance to clock jitter.
The PCM5242 integrates a fully programmable
miniDSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators and
other differentiating features to their products.
The PCM5242 provides 4.2VRMS ground-centered
differential 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 PLL on the device removes the
requirement for a system clock (commonly known as
master clock), allowing a 3-wire I2S connection and reducing system EMI.
