3 Description
The PCM514x devices are a family of monolithic
CMOS-integrated circuits that include a stereo digital-
to-analog converter and additional support circuitry in
a small TSSOP package. 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 miniDSP 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 charge-
pump-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 (commonly known as
master clock), allowing a 3-wire I2S connection and
reducing system EMI.
