3 Description

Using Directpath charge-pump technologythe
PCM510xAdevicesprovide2.1-Vmsground
centered outputs,allowing designers to eliminate DC
blocking capacitors on the output. as well as extenal
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 per pin.
The integrated PLL on the device removes the
requirement for a system clock(commonly known as
master clock),allowing a 3-wire i's connection and
reducing system EMI.
Intelligent clock error and PowerSense undervoltage
protection utilizes a two-level mute system for pop-
free performance.
Compared with many conventional switched capacitor
DAC architectures.the PcM510xAfamily offers up to
20 dB lower out-of-band noise.reducing EMland
