PCM2707 USB to SPDIF (and I2S) converter
About:
This PCB hosts a Texas Instruments
PCM2707 USB Audio Codec and features
SPDIF output or I2S output (configurable via a jumper). It uses USB bus power for the power
supply of the chip or optionally an external 5v power supply.
The current variant of the chip is the PCM2707C but it will
work with older variants, too.
One of the design goals was a widely undisturbed groundplane under and around the chip
and the placement of decoupling capacitors as close as possible to the pins of the chip.
All power supply lines to the chip also have ferrite beads in series.
This board was designed in 2008 and recently updated to
use components/3d models from the Target 3001 standard component library. The PCB design file can
be downloaded in the files section.
