DESCRIPTION
The PCM510x 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 PCM510x
uses the latest generation of TI’s advanced segment
DAC architecture to achieve excellent dynamic
performance and improved tolerance to clock jitter.
The PCM510x devices are simpler hardware
controlled 2V_RMS DACs, with filter select, PLL and
auto-mute functions.
The PCM510x provides 2.1V_RMS 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 1kΩ.
By supporting loads down to 1kΩ, the PCM510x can
essentially drive up to 10 products in parallel. (LCD
TV, DVDR, AV Receivers etc).
The integrated PLL on the device removes the
requirement for a system clock (commonly known as
master clock). This allows a 3-wire I²S connection,
along with reduced system EMI.
Intelligent clock error and PowerSense under voltage
protection utilizes a two level mute system for
pop-free performance. Upon clock error or system
power failure, the device digitally attenuates the data
(or last known good data), then mutes the analog
circuit
Compared with existing DAC technology, the
PCM510x family offers up to 20dB lower out-of-band
noise, reducing EMI and aliasing in downstream
amplifiers/ADCs. (from traditional 100kHz OBN
measurements all the way to 3MHz)
The PCM510x accepts industry-standard audio data
formats with 16- to 32-bit data. Sampling rates up to
384kHz are supported.
